  • X won't start, root filesystem mounted read only

    - by TK Kocheran
    I just experienced a very strange and puzzling problem on my machine that I can't seem to get sorted out. I was running Windows on a second partition, and everything was working great. I then went to restart into Linux, and noticed that X wouldn't start. Everything was displayed in super-low resolution, so I tried reinstalling my NVIDIA driver. I started seeing all of these I/O error problems, so I figured that my SSD was bad. After a bit more playing around, I ran fsck on the drive when mounted from a startup disk as well as badsectors and everything looked great. The SMART drive tests all passed and again, everything was looking good, so I rebooted again and still, no joy. I started then getting some weird USB errors, so I followed someone's advice and unplugged my computer's power supply, then started back up again and my graphics looked a lot better in the BIOS and in the boot logo, but X still wouldn't start. I then found out that my main boot drive was being mounted read-only for some reason. What's going wrong? I've done some pretty extensive tests on the SSD from a startup disk such as writing massive files, reading big files, running filesystem checks on the entire disk, and everything is looking great, until I try to boot. Whenever I try installing the drivers with apt-get, I get a ton of ata error messages looking like this: How can I diagnose what's going wrong and fix it so I can get back to work?

  • WIN7 and Ubuntu lost after Installing ubuntu 12.04 and win7 dual system ,I have no OS on my laptop now

    - by abos
    Here is the procedure: In the morning I installed ubuntu using a USB directly without config any thing to my win7 system. After install complete, ubuntu installation software tell me to reboot.And everything is just find. While rebooting, there is NO UBUNTU system for me to select,and my laptop go straight to log in using WIN7. NO ubuntu shows on WIN7's configuration(Default System). Log in ubuntu using usb(try ubuntu without installation), I can find ubuntu's filesystem was already there. Formatting the disk on WIN7's disk management, rearranging them to other disk.Still having no trouble with WIN7. In the afternoon try a few times of installation and uninstallation of ubuntu. still shows no sign of selecting ubuntu system. In the evening another trial while installing ubuntu with the third option of: installing ubuntu alongside with INW7, erase win7 and install ubuntu. somethingelse --- my check failed with configuartion for what comes out with the 'something else' option,reboot. And I have no system now with some cmd tips say: Reboot and Select proper Boot Device or Insert Boot Media in selected Boot device and press a key. Files those on win7's orginal file system and Ubuntu filesystem can still be found when I 'try ubuntu without installation'. 5.But I just got no OS when I reboot my laptop normally.

  • Partition does not start on physical sector boundary?

    - by jasmines
    I've one HD on my laptop, with two partitions (one ext3 with Ubuntu 12.04 installed and one swap). fdisk is giving me a Partition 1 does not start on physical sector boundary warning.

  • What is the recommended way to empty a SSD?

    - by Lekensteyn
    I've just received my new SSD since the old one died. This Intel 320 SSD supports TRIM. For testing purposes, my dealer put malware, err, Windows on it. I want to get rid of it and install Kubuntu on it. It does not have to be a "secure wipe", I just need the empty the disk in the mosy healthy way. I believe that dd if=/dev/zero of=/dev/sda just fills the blocks with zeroes and thereby taking another write (correct me if I'm wrong). I've seen the answer How to enable TRIM, but it looks like it's suited for clearing empty blocks, not wiping the disk. hdparm seems to be the program to do it, but I'm not sure if it clears the disk OR cleans empty blocks. From its manual page: --trim-sector-ranges For Solid State Drives (SSDs). EXCEPTIONALLY DANGEROUS. DO NOT USE THIS OPTION!! Tells the drive firmware to discard unneeded data sectors, destroying any data that may have been present within them. This makes those sectors available for immediate use by the firmware's garbage collection mechanism, to improve scheduling for wear-leveling of the flash media. This option expects one or more sector range pairs immediately after the option: an LBA starting address, a colon, and a sector count, with no intervening spaces. EXCEPTIONALLY DANGEROUS. DO NOT USE THIS OPTION!! E.g. hdparm --trim-sector-ranges 1000:4 7894:16 /dev/sdz How can I make all blocks appear as empty using TRIM?

  • I installed ubuntu, the installer told me to reboot afterwards. I dd, and now linux wont boot

    - by mandy
    Im trying to dual boot between mac 10.6.8 and ubuntu 11.10. I have a macbook pro 8,1. So i installed from a 10.04 disk because the install window makes more sense to me, and it doesnt give me errors or anything. Also, any versions of ubuntu after that dont boot from disk for whatever reason. (i think its having to do with the efi boot thing. i have to get ubuntu 11.10 to boot from a usb with folders bootefiboot.iso) Then my plan after that was after the ubuntu 10.04 install took care of all the swap and stuff for me without being messy, to upgrade to 11.10. So here i have 10.04 booting successfully back and forth from mac osx no problem. I put in my 11.10 usb and the installer gives me the option to "update 10.04 to 11.10" bingo, jackpot, thats what i want. Everything proceeds as normal, as EVERY OTHER install of ubuntu i have ever done, then the installer finishes and says HEY! im finished! Continue testing or reboot now! So i reboot, and what do i get??? A black screen that says the file system isnt found, to enter a boot disk and press any key. WHAT THE HELL????? so i boot the 11.10 installer again from usb, and select "erase 11.10 and install 11.10", installer proceeds normally, and asks me to reboot. I reboot and get the SAME THING. Please, someone, help me get this right here. This is my first time actually dual booting between mac and linux. Usually i just wipe off osx completely and install ubuntu but i actually need to keep my mac partition this time. I have successfully installed 11.10 on this machine before, but that was when i did a clean install. Help?

  • GRUB2 stuck at rescue console, showing "unknown filesystem" for all partitions

    - by AndiDog
    I installed Ubuntu 12.04 on my external USB drive, where I have a 700GB NTFS partition followed by the new 6GB ext4 partition and a swap partition (all primary). The GRUB MBR is also installed to the external hard disk. Since my BIOS puts the external drive as first disk when booting, I removed my internal hard disk before installation in order to avoid ordering problems. Now when I boot from the external drive, GRUB is stuck at the rescue console with the error "unknown filesystem". grub rescue> ls (hd0) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1) ls (hd0,<any of them>)/ gives me "unknown filesystem", thus also "insmod normal" GRUB doesn't seem to be able to read my Linux partition as you can see above?! How can I solve this? Additional info: bootinfoscript says (this is with the internal drive in again, but that does not make a difference): Grub2 (v1.99) is installed in the MBR of /dev/sdb and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos2)/boot/grub on this drive. sdb1: __________________________________________________________________________ File system: ntfs Boot sector type: Windows Vista/7: NTFS Boot sector info: No errors found in the Boot Parameter Block.

  • How to modify partitions after install?

    - by ChocoDeveloper
    I wanted to have Ubuntu with full disk encryption on one big partition, and Windows on a small one. In 12.04, only the Server Edition installer has full disk encryption, so I used that and then installed ubuntu-desktop. When it asked for the size, I reduced it from ~999GB to ~750gb. Now after the install, on both gparted and disk utility I see /dev/sda2 taking ~931GB, and nothing unallocated, so I can't create a partition for windows. I got the size right, because when I right-click inside a folder, then hit 'properties', I see Free space: ~690GB (I don't know why it's not ~750GB, but at least it's not 900). The command df -h shows the same. So what can I do? Normally I would just resize a partition with gparted to create unallocated space, then create the partition. But here I have two problems: gparted does not seem to be showing the correct values, and also it says it does not support LUKS so I'm afraid it will mess things up. Any thoughts?

  • Install Ubuntu side by side with Windows

    - by Igal
    I'm trying to setup both Windows 7 and Ubuntu 14.04 Desktop on the same machine. I've partitioned the disk into 3 parts, so that I can have Windows Ubuntu Shared Partition for Files I've installed Windows 7 on the first partition (which created a small partition of 100MB for boot), so now I have 4 partitions on the disk which is all it can take. Now I am installing Ubuntu, and it's asking me whether I want to: Install Ubuntu inside Windows 7 Replace Windows 7 with Ubuntu (No!) Something else I want the Ubuntu installation to go into the partition that I prepared for it. Should I choose "Something else"? If I do so -- will I be able to choose which OS to load at boot? Can anyone explain how "Ubuntu inside Windows" work? it says that it will allow me to choose which OS to load at boot, which is desired. UPDATE: When choosing "Something else" I see also an option for Device for Boot Loader Installation: /dev/sda -- the ssd disk itself /dev/sda1 -- the Windows 7 loader (100MB partition) /dev/sda4 -- which is one of the other partitions Which one should I choose there? TIA!

  • Grub menu not waiting despite of GRUB_TIMEOUT=10

    - by Optimus
    I have Ubuntu 12.04 installed along side of windows 7. The grub menu doesn't seem obey GRUB_TIMEOUT=10, I see the grub menu there for a split second and it immediately defaults to the first option. Grub menu worked fine when I first installed ubuntu. I am not able to pinpoint what exactly broke it(maybe some update?). I did resize my ubuntu partition using gparted but am not sure if that is what caused it. here are my settings from etc/default/grub GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 #GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" How do I fix this? Edit: As suggested by 'kamil' this is what I have tried so far with no luck - 1) hold the shift key while booting 2) sudo gedit /etc/default/grub edit GRUB_TIMEOUT to `GRUB_TIMEOUT=10` sudo update-grub 3) sudo gedit /etc/default/grub edit GRUB_TIMEOUT to `GRUB_TIMEOUT=10` sudo update-grub2 4) at the end of your /etc/grub.d/00_header file, comment out the if condition except for the regular set timeout line like this: #if [ \${recordfail} = 1 ]; then # set timeout=-1 #else set timeout=${GRUB_TIMEOUT} #fi then sudo update-grub and sudo update-grub2 5) install boot repair sudo add-apt-repository ppa:yannubuntu/boot-repair sudo apt-get update sudo apt-get install -y boot-repair boot-repair boot-repair output - Boot successfully repaired. ... The boot files of [The OS now in use - Ubuntu 12.04.1 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, 200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition) http://paste.ubuntu.com/1220468/ - here is the full boot-repair data Could grub files not being at the start of the disk create such issues?

  • Can't start system due to mdadm failing

    - by user101212
    I used to have a 5-disk RAID5 partition, all working very well. I have then decided to add 3 more disks on it, totaling 8 equal disks. I've opened Webmin and just asked to add the disks. Then I've realized the three disks had NTFS partitions, wich mdadm didn't complain, so I tried to stop the growing to remove the Windows partitions. I've tried to remove a disk using the same Webmin, but (as you might guess and call me fool...), the system became unstable. By restarting the system, I've started receiving these messages: "udev[126]: timeout: killing '/sbin/mdadm --incremental /dev/sdh1' [311]" "udev[124]: timeout: killing '/sbin/mdadm --detail --export /dev/md0' [316]" I've formated the system disk, hoping to get a system up and running. I did that with all RAID disks disconected, so everything was fine. I then reconnected the disks, wich was also ok. And finally installed mdadm using apt-get. By reboot, the system has found the mdadm intention of growing the system, so the same messages appear again. I other words: I can't even reach a command prompt to do something. Any ideas of what to do? I believe I could turn off the system, disconnect the disks and look for the mdadm.conf file. Would that be a good idead? I'm no Linux expert, so I'm really lost here.

  • How do I add a boot from cd option to yaboot?

    - by Sergiu
    So I'm dual-booting Ubuntu 12.04.1 on my iMac G5 powepc alongside Mac OS X and I want to add a boot cd option to yaboot because I'm trying to boot a scratched Mac OS X installation DVD that takes a while to read and the frst bootstrap moves on too fast. How do I edit the timeout for the first bootstrap anyways? So, my main question is, how do I add a cd booting option to yaboot and then, how doI boot it? The devalias from OpenFrmware tells me that 1 have 2 cd-rom instaled, on is /ht/pci@3/ata-6/disk@0 and the other on ends with a 1 instead of a zero. These are the contents of my yaboot.conf file: yaboot.conf generated by the Ubuntu installer run: "man yaboot.conf" for details. Do not make changes until you have!! see also: /usr/share/doc/yaboot/examples for example configurations. For a dual-boot menu, add one or more of: bsd=/dev/hdaX, macos=/dev/hdaY, macosx=/dev/hdaZ boot="/dev/disk/by-id/scsi-SATA_ST3160023AS_5MT1GCWA-part2" device=/ht@0,f2000000/pci@3/k2-sata-root@c/@0/@0 partition=4 root="UUID=798a048f-ee48-49e0-bba3-111aed8dee04" timeout=12000 install=/usr/lib/yaboot/yaboot magicboot=/usr/lib/yaboot/ofboot enablecdboot macosx="/dev/disk/by-id/scsi-SATA_ST3160023AS_5MT1GCWA-part3" image=/boot/vmlinux label=Linux read-only initrd=/boot/initrd.img append="quiet splash" What do I add here so that yaboot will boot from my cd in like 3 minutes after startup? Thanks!

  • Will Ubuntu Live CD move MFT to resize NTFS volumes?

    - by irwazr
    I have a feeling some will consider this a duplicate, but please hear me out. I've been reading tons of questions and threads around this but have never really found an answer for this specifically. I want to shrink my NTFS partition to make room for a Ubuntu install, so I can dual boot them. However when shrinking the NTFS volume in Windows disk management, it will only go so far as the MFT is sitting near the end of the volume. I've read plenty of posts about why it does this, and how difficult/dangerous it is to move the MFT etc. I've also read that Perfect Disk can apparently do it under it's trial period, but I remain cautious to try this method. I was wondering however if the disk partitioning utility included in the Ubuntu install wizard handles the moving of the MFT when dragging the partition boundaries. It all seems too simple that you simply tell it the new size you want it to be. Would it tell me if it couldn't resize by the amount you requested if the MFT was an issue, or move it for you if it were able. I'm concerned it might corrupt the MFT and the volume, even though I doubt the install wizard would be so daft. So what exactly is the deal with the partition resizing tool in the Ubuntu install wizard? Will it safely resize my NTFS volume despite the location of my MFT? Thanks in advance.

  • Ubuntu cannot see Windows 7 partitions on install

    - by Nash0
    I've been trying to install Ubuntu 10.10 as a dual boot with Windows 7 on my Dell latitude e6510. It is currently running Windows 7 and I have used the MS disk tools to shrink the Win 7 NTFS partition to make room for Linux. The issue I'm having is that when I run Ubuntus installer by booting from CD it sees the entire hard drive as unallocated space. I have also tried Kbuntu 10.10, Fedora 14, booting a Gparted 0.8.0 usb drive, and Ubuntu "install in Windows" with wubi they all have problems. EDIT: When I run the "try Ubuntu" option on booting from cd it can mount my Windows partition and I can view the files. The output of sudo parted -l when running in try Ubuntu mode: Warning: /dev/sda contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? Yes/No? yes Model: ATA ST9500420AS (scsi) Disk /dev/sda: 500GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.

  • Thunderbird: "Could not initialize the application's security component" [closed]

    - by user unknown
    In Thunderbird, on startup, I get the error message: "Could not initialize the application's security component" The message continues to check permissions of the profile, and free disk space. df -h shows, that I have 19G free disk space. find . -not -perm -644 -not -perm -600 -ls shows: No file without rw-permissions for me. Before the error occured, thunderbird worked well. But I changed my main mail-account. I had two, let's call them A and B, and used mainly A, but now I wanted to deaktivate it, and receive and send automatically via the second. I Had problems moving the filters from inbox A to inbox B (missing copy-functionality). In the web, I found (mollazine) hints, to move key3.db, cert8.db and secmode.db out of the way, but it didn't work for me. Another hint was to uninstall Quickcam(?. sic!), but I don't have Quickcam. A third to recreate the profile, but I have subdirectories, filters, addressbook, groups - mails back to the year 2003. I don't want to risk the loss of data. The whole errormessage is: Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features. When I open the error-console, it is empty.

  • How do I get my internal HDD to mount at startup?

    - by el_gallo_azul
    It's either not intuitive or not working in Ubuntu 14.04. I want to mount my internal HDD at at startup (I boot from an SSD). I attempt to set this, following this procedure: Open Disks utility Select the disk Below the disk's Volumes, click on the More actions button Select Edit Mount Options... Select Automatic Mount Options "Off" Under Mount Options, ensure that Mount at startup is selected Click OK Enter password into Authenticate dialog box Restart but this procedure doesn't work. Upon rebooting, and after Grub attempts to start Ubuntu, I receive the error message "An error occurred while mounting /mnt/4f721fc0-8072-453f-b48f-ca686bd89549. Press S to skip mounting or M for manual recovery". That identifier "4f721fc0-8072-453f-b48f-ca686bd89549" was automatically assigned by Ubuntu. I press S and the boot process continues OK. If I try to mount the disk immediately after booting, I receive the error message "Unable to access "Storage"" (I named the volume Storage). So then I start the Disks utility and set it to Automatic Mount Options "On" and reboot. To me, it seems like this should work, but it doesn't. Here are a number of photos of the process (Alt+PrtScn doesn't work after selecting More actions).

  • Need help with PHP web app bootstrapping error potentially related to Zend [migrated]

    - by Matt Shepherd
    I am trying to get a program called OpenFISMA running on an Ubuntu AMI in AWS. The app is not really coded on the Ubuntu platform, but I am in my comfort zone there, and have tried both CentOS and OpenSUSE (both are sort of "native" for the app) for getting it working with the same or worse results. So, why not just get it working on Ubuntu? Anyway, the app is found here: www.openfisma.org and an install guide is found here: https://openfisma.atlassian.net/wiki/display/030100/Installation+Guide The install guide kind of sucks. It doesn't list dependencies in any coherent way or provide much of any detail (does not even mention Zend once on the entire page) so I've done a lot of work to divine the information I do have. This page provided some dependency inf (though again, Zend is not mentioned once): https://openfisma.atlassian.net/wiki/display/PUBLIC/RPM+Management#RPMManagement-BasicOverviewofRPMPackages Anyway, I got all the way through the install (so far as I could reconstruct it). I am going to the login page for the first time, and there should be some sort of bootstrapping occurring when I load the page. (I am not a programmer so I have no idea what it is doing there.) Anyway, I get a message on the web page that says: "An exception occurred while bootstrapping the application." So, then I go look in /var/www/data/logs/php.log and find this message: [22-Oct-2013 17:29:18 UTC] PHP Fatal error: Uncaught exception 'Zend_Exception' with message 'No entry is registered for key 'Zend_Log'' in /var/www/library/Zend/Registry.php:147 Stack trace: #0 /var/www/public/index.php(188): Zend_Registry::get('Zend_Log') #1 {main} thrown in /var/www/library/Zend/Registry.php on line 147 This occurs every time I load the page. I gather there is an issue related to registering the Zend_Log variable in the Zend registry, but other than that I really have no idea what to do about it. Am I missing a package that it needs, or is this app not coded to register the variables properly? I have no clue. Any help is greatly appreciated.

  • Using Oracle Enterprise Manager Ops Center to Update Solaris via Live Upgrade

    - by LeonShaner
    Introduction: This Oracle Enterprise Manager Ops Center blog entry provides tips for using Ops Center to update Solaris using Live Upgrade on Solaris 10 and Boot Environments on Solaris 11. Why use Live Upgrade? Live Upgrade (LU) can significantly reduce downtime associated with patching Live Upgrade avoids dropping to single-user mode for long periods of time during patching Live Upgrade relies on an Alternate Boot Environment (ABE)/(BE), which is patched while in multi-user mode; thereby allowing normal system operations to continue with the active BE, while the alternate BE is being patched Activating an newly patched (A)BE is essentially a reboot; therefore the downtime is ~= reboot Admins can easily revert to the prior Boot Environment (BE) as a safeguard / fallback. Why use Ops Center to patch via Live Upgrade, Alternate Boot Environments, and Solaris 11 equivalents? All the benefits of Ops Center's extensive patch and package knowledge base can be leveraged on top of Live Upgrade Ops Center can orchestrate patching based on Live Upgrade and Solaris 11 features, which all works together to minimize downtime Ops Centers advanced inventory and reporting features assurance that each OS is updated to a verifiable, consistent standard, rather than relying on ad-hoc (error prone) procedures and scripts Ops Center gives admins control over the boot environment specifications or they can let Ops Center decide when a BE is necessary, thereby reducing complexity and lowering the opportunity for user error Preparing to use Live Upgrade-like features in Solaris 11 Requirements and information you should know: Global Zone Root file-systems must be separate from Solaris Container / Zone filesystems Solaris 11 has features which are similar in concept to Live Upgrade on Solaris 10, but differ greatly in implementationImportant distinctions: Solaris 11 assumes ZFS root Solaris 11 adds Boot Environments (BE's) as an integrated feature (see beadm) Solaris 11 BE's avoid single-user patching (vs. Solaris 10 w/ ZFS snapshot=ABE). Solaris 11 Image Packaging System (IPS) has hooks for BE creation, as needed Solaris 11 allows pkgs to be installed + upgraded in alternate BE (e.g. instead of the live system) but it is controlled on a per-pkg basis Boot Environments are activated across a reboot; instead of spending long periods installing + upgrading packages in single user mode. Fallback to a prior BE is a function of the BE infrastructure (a la beadm). (Generally) Reboot + BE activation can be much much faster on Solaris 11 Preparing to use Live Upgrade on Solaris 10 Requirements and information you should know: Global Zone Root file-systems must be separate from Solaris Container / Zone filesystems Live Upgrade Pre-requisite patches must be applied before the first Live Upgrade Alternate Boot Environments are created (see "Pre-requisite Patches" section, below...) Solaris 10 Update 6 or newer on ZFS root is the practical starting point for Live Upgrade Live Upgrade with ZFS root is far more straight-forward than any scheme based on Alternative Boot Environments in slices or temporarily breaking mirrors Use Solaris best practices to upgrade the OS to at least Solaris 10 Update 4 (outside of Ops Center) UFS root can (technically) be used, but it is significantly more involved (e.g. discouraged) -- there are many reasons to move to ZFS while going through the process to update to Solaris 10 Update 6 or newer (out side of Ops Center) Recommendation: Start with Solaris 10 Update 6 or newer on ZFS root Recommendation: Start with Ops Center 12c or newer Ops Center 12c can automatically create your ABE's for you, without the need for custom scripts Ops Center 12c Update 2 avoids kernel panic on unpatched Solaris 10 update 9 (and older) -- unrelated to Live Upgrade, but more on the issue, below. NOTE: There is no magic!  If you have systems running Solaris 10 Update 5 or older on UFS root, and you don't know how to get them updated to Solaris 10 on ZFS root, then there are services available from Oracle Advanced Customer Support (ACS), which specialize in this area. Live Upgrade Pre-requisite Patches (Solaris 10) Certain Live Upgrade related patches must be present before the first Live Upgrade ABE's are created on Solaris 10.Use the following MOS Search String to find the “living document” that outlines the required patch minimums, which are necessary before using any Live Upgrade features: Solaris Live Upgrade Software Patch Requirements(Click above – the link is valid as of this writing, but search in MOS for the same "Solaris Live Upgrade Software Patch Requirements" string if necessary) It is a very good idea to check the document periodically and adapt to its contents, accordingly.IMPORTANT:  In case it wasn't clear in the above document, some direct patching of the active OS, including a reboot, may be required before Live Upgrade can be successfully used the first time.HINT: You can use Ops Center to determine what to expect for a given system, and to schedule the “pre-patching” during a maintenance window if necessary. Preparing to use Ops Center Discover + Manage (Install + Configure the Ops Center agent in) each Global Zone Recommendation:  Begin by using OCDoctor --agent-prereq to determine whether OS meets OC prerequisites (resolve any issues) See prior requirements and recommendations w.r.t. starting with Solaris 10 Update 6 or newer on ZFS (or at least Solaris 10 Update 4 on UFS, with caveats) WARNING: Systems running unpatched Solaris 10 update 9 (or older) should run the Ops Center 12c Update 2 agent to avoid a potential kernel panic The 12c Update 2 agent will check patch minimums and disable certain process accounting features if the kernel is not sufficiently patched to avoid the panic SPARC: 142900-05 Obsoleted by: 142900-06 SunOS 5.10: kernel patch 10 Oracle Solaris on SPARC (32-bit) X64: 142901-05 Obsoleted by: 142901-06 SunOS 5.10_x86: kernel patch 10 Oracle Solaris on x86 (32-bit) OR SPARC: 142909-17 SunOS 5.10: kernel patch 10 Oracle Solaris on SPARC (32-bit) X64: 142910-17 SunOS 5.10_x86: kernel patch 10 Oracle Solaris on x86 (32-bit) Ops Center 12c (initial release) and 12c Update 1 agent can also be safely used with a workaround (to be performed BEFORE installing the agent): # mkdir -p /etc/opt/sun/oc # echo "zstat_exacct_allowed=false" > /etc/opt/sun/oc/zstat.conf # chmod 755 /etc/opt/sun /etc/opt/sun/oc # chmod 644 /etc/opt/sun/oc/zstat.conf # chown -Rh root:sys /etc/opt/sun/oc NOTE: Remove the above after patching the OS sufficiently, or after upgrading to the 12c Update 2 agent Using Ops Center to apply Live Upgrade-related Pre-Patches (Solaris 10)Overview: Create an OS Update Profile containing the minimum LU-related pre-patches, based on the Solaris Live Upgrade Software Patch Requirements, previously mentioned. SIMULATE the deployment of the LU-related pre-patches Observe whether any of the LU-related pre-patches will require a reboot The job details for each Global Zone will advise whether a reboot step will be required ACTUALLY deploy the LU-related pre-patches, according to your change control process (e.g. if no reboot, maybe okay to do now; vs. must do later because of the reboot). You can schedule the job to occur later, during a maintenance window Check the job status for each node, resolving any issues found Once the LU-related pre-patches are applied, you can Ops Center to patch using Live Upgrade on Solaris 10 Using Ops Center to patch Solaris 10 with LU/ABE's -- the GOODS!(this is the heart of the tip): Create an OS Update Profile containing the patches that make up your standard build Use Solaris Baselines when possible Add other individual patches as needed ACTUALLY deploy the OS Update Profile Specify the appropriate Live Upgrade options, e.g. Synchronize the active BE to the alternate BE before patching Do not activate the BE after patching Check the job status for each node, resolving any issues found Activate the newly patched BE according to your change control process Activate = Reboot to the ABE, making the ABE the new active BE Ops Center does not separate LU activate from reboot, so expect a reboot! Check the job status for each node, resolving any issues found Examples (w/Screenshots) Solaris 10 and Live Upgrade: Auto-Create the Alternate Boot Environment (ZFS root only) ABE to be created on ZFS with name S10_12_07REC (Example) Uses built in feature to call “lucreate -n S10_12_07REC” behind scenes if not already present NOTE: Leave “lucreate” params blank (if you do specify options, the will be appended after -n $ABEName) Solaris 10 and Live Upgrade: Alternate Boot Environment Creation via Operational Profile (script) The Alternate Boot Environment is to be created via custom, user-supplied script, which does whatever is needed for the system where Live Upgrade will be used. Operational Profile, which provides the script to create an ABE: Very similar to the automatic case, but with a Script (Operational Profile), which is used to create the ABE Relies on user-supplied script in the form of an Operational Profile Could be used to prepare an ABE based on a UFS root in a slice, or on a separate device (e.g. by breaking a mirror first) – it is up to the script author to do the right thing! EXAMPLE: Same result as the ZFS case, but illustrating the Operational Profile (e.g. script) approach to call: # lucreate -n S10_1207REC NOTE: OC special variable is $ABEName Boot Environment Profile, which references the Operational Profile Script = Operational Profile on this screen Refers to Operational Profile shown in the previous section The user-supplied S10_Create_BE Operational Profile will be run The Operational Profile must send a non-zero exit code if there is a problem (so that the OS Update job will not proceed) Solaris 10 OS Update Profile (to provide the actual patch specifications) Solaris 10 Baseline “Recommended” chosen for “Install” Solaris 10 OS Update Plan (two-steps in this case) “Create a Boot Environment” + “Update OS” are chosen. Using Ops Center to patch Solaris 11 with Boot Environments (as needed) Create a Solaris 11 OS Update Profile containing the packages that make up your standard build ACTUALLY deploy the Solaris 11 OS Update Profile BE will be created if needed (or you can stipulate no BE) BE name will be auto-generated (if needed), or you may specify a BE name Check the job status for each node, resolving any issues found Check if a BE was created; if so, activate the new BE Activate = Reboot to the BE, making the new BE the active BE Ops Center does not separate BE activate from reboot NOTE: Not every Solaris 11 OS Update will require a new BE, so a reboot may not be necessary. Solaris 11: Auto BE Create (as Needed -- let Ops Center decide) BE to be created as needed BE to be named automatically Reboot (if necessary) deferred to separate step Solaris 11: OS Profile Solaris 11 “entire” chosen for a particular SRU Solaris 11: OS Update Plan (w/BE)  “Create a Boot Environment” + “Update OS” are chosen. Summary: Solaris 10 Live Upgrade, Alternate Boot Environments, and their equivalents on Solaris 11 can be very powerful tools to help minimize the downtime associated with updating your servers.  For very old Solaris, there are some important prerequisites to adhere to, but once the initial preparation is complete, Live Upgrade can be used going forward.  For Solaris 11, the built-in Boot Environment handling is leveraged directly by the Image Packaging System, and the result is a much more straight forward way to patch, and far fewer prerequisites to satisfy in getting there.  Ops Center simplifies using either approach, and helps you improve consistency from system to system, which ultimately helps you improve the overall up-time across all the Solaris systems in your environment.

    Hi, i have a windows application and i need to change it into a windows service, How can i check whether the windows service is running or not without using any external service to keep a check on the main service. Is there any way to check it within the main service as i have tried work on it but if the windows service is stopped then there is no way i can check on it. Do i have to implement the thread(keep alive thread) for this, if so then how to do it. Please help. Thanks in adv.

  • Test to identify your development environment?

    - by lance
    The code has a runtime dependency which is not available in our development environment (and is available in test and prod). It's expensive to actually test for the dependency, and I want to test for the environment instead. if (isDevEnvironment) { // fake it } else { // actually do it } Without using appSettings, what code/technique/test would you use to set isDevEnvironment? Example answers: check machine name (partial or full) check for running instance of Visual Studio check for environment variable I'm hoping for a test I hadn't considered.

  • Validating a class using DataAnotations

    - by runxc1 Bret Ferrier
    I have a class that I am using to model my data in MVC. I have added some DataAnotations to mark fields that are required and I am using regular expressions to check valid Email Addresses. Everything works fine if the object is posted back to MVC and I have the ModelState property that I can check to confirm that the class is valid but how do I check to see if the class is valid outside of MVC using the same class and Data Anotations that I have already set up?

  • error C2784: Could not deduce template argument

    - by atch
    Hi guys, Still fighting with templates. In this example, despite the fact that is copied straight from a book I'm getting the following error message: Error 2 error C2784: 'IsClassT<T>::One IsClassT<T>::test(int C::* )' : could not deduce template argument for 'int C::* ' from 'int'. This is an example from a book Templates - The Complete Guide. (I work with Visual Studio 2010 RC). template<typename T> class IsClassT { private: typedef char One; typedef struct { char a[2]; } Two; template<typename C> static One test(int C::*); template<typename C> static Two test(…); public: enum { Yes = sizeof(IsClassT<T>::test<T>(0)) == 1 }; enum { No = !Yes }; }; class MyClass { }; struct MyStruct { }; union MyUnion { }; void myfunc() { } enum E {e1} e; // check by passing type as template argument template <typename T> void check() { if (IsClassT<T>::Yes) { std::cout << " IsClassT " << std::endl; } else { std::cout << " !IsClassT " << std::endl; } } // check by passing type as function call argument template <typename T> void checkT (T) { check<T>(); } int main() { /*std::cout << "int: "; check<int>(); */ std::cout << "MyClass: "; check<MyClass>(); } And although I know roughly what's going on in this example I cannot fix this error. Thanks for help.
