  • Can't log in after restoring from Time Machine

    - by Jay Conrod
    My friend uses a Macbook Pro with Snow Leopard 10.6.2. She uses both FileVault and Time Machine to preserve her data. Recently, she suffered a hard disk failure. After restoring from Time Machine using the Snow Leopard install disk, she gets the following error when logging in: You are unable to log in to the FileVault user account at this time. Logging into the account failed because an error occurred. When examining the file system through Terminal, I noticed her home directory is not present: there is no /Users/username directory, or the FileVault .sparsebundle file that's supposed to be there. When using Time Machine.app on /Users, it appears as if her home directory as never there. Additionally, I did a search on the backup disk with the following command: sudo find /Volumes/backup -name '*.sparsebundle' No results. She told me that after working with some large data files, Time Machine would come on, and it would sound like it was transferring a lot of data to the hard disk. Time Machine must have been doing something, right? How can we recover her files? Are they still there?

  • How do you monitor SSD wear in Windows when the drives are presented as 'generic' devices?

    - by MikeyB
    Under Linux, we can monitor SSD wear fairly easily with smartmontools whether the drive is presented as a normal block device or a generic device (which happens when the drive has been hardware RAIDed by certain controllers such as the one on the IBM HS22). How can we do the equivalent under Windows? Does anyone actually use smartmontools? Or are there other packages out there? The problem is that SCSI Generic devices just don't show up in Windows. If the drives aren't RAIDed we can see them fine. How I'd do it in Linux: sles11-live:~ # lsscsi -g [1:0:0:0] disk SMART USB-IBM 8989 /dev/sda /dev/sg0 [2:0:0:0] disk ATA MTFDDAK256MAR-1K MA44 - /dev/sg1 [2:0:1:0] disk ATA MTFDDAK256MAR-1K MA44 - /dev/sg2 [2:1:8:0] disk LSILOGIC Logical Volume 3000 /dev/sdb /dev/sg3 sles11-live:~ # smartctl -l ssd /dev/sg1 smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32.49-0.3-default] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Device Statistics (GP Log 0x04) Page Offset Size Value Description 7 ===== = = == Solid State Device Statistics (rev 1) == 7 0x008 1 26~ Percentage Used Endurance Indicator |_ ~ normalized value sles11-live:~ # smartctl -l ssd /dev/sg2 smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32.49-0.3-default] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Device Statistics (GP Log 0x04) Page Offset Size Value Description 7 ===== = = == Solid State Device Statistics (rev 1) == 7 0x008 1 3~ Percentage Used Endurance Indicator |_ ~ normalized value

  • How to bypass resume from hibernate [closed]

    - by Daniel Trebbien
    I am attempting to resume a Windows Vista laptop from hibernate, but the resume process seems to be stuck in an endless loop in which Windows is repeatedly trying to read from the optical drive. When I press the Power On button on the laptop, the screen is black (not even the backlight turns on) and the following occurs in a loop: Five seconds pass and I hear the optical drive being accessed. (There's no disk in the drive, so it sounds like a short buzzing noise.) Two seconds pass and I hear the optical drive being accessed. Two seconds pass and I hear the optical drive being accessed. So it's three short buzzing noises in a row, over and over again. Eventually I have to abruptly power off the machine. I have tried inserting a data CD into the drive as well as a bootable CD (a live Linux distro boot disk). For both, the optical drive spins up for a bit, but stops after Windows decides that the disk is not what it is looking for. I have since lost the Windows Vista recovery DVD, but I don't know if inserting the recovery disk into the optical drive would have a different effect than the bootable CD. I have tried pressing F8 immediately after pressing the Power On button (hoping to enter System Restore), but that did not have an effect. Is there a special key sequence that will cause Windows to bypass resuming from hibernate, effectively ignoring hiberfil.sys?

  • VMware vSphere 4.1 and BackupExec 2010

    - by Josh
    I'm sure a common problem with most shops is backups, their size, and the window in which you have to back up the data. What we are working with: VMware vSphere 4.1 Cluster PS4000XV Equallogic Storage Array (1.6TB Volume dedicated for Backup to Disk) Physical Backup Server with a single LTO4 drive. BackupExec 2010 R3 with the following agents, Exchange, SQL, Active Directory, VMware. Dual Gigabit MPIO Connections between all devices (Storage Array, Backup Server, VM Hosts) What we would like to accomplish: I would like to implement an efficient Backup to Disk to Tape solution where all of our VMs are backed up to the Storage Array first, and then once completely backed up to the array are replicated to tape. In the event we needed to recover, we would be able to do so directly from tape. Where we are at currently. Of the several ways I have setup the jobs in Backup Exec 2010 R3 the backup jobs all queue up at the same time, as soon as a job is finished backing up to disk it then starts that same job to tape, but pulling from the original source instead of the designated B2D location. I understand that I could create a job that backs up the "Backup to Disk" folder to tape, but in the event of restoration, I would first need to stage the data in the B2D folder before I could restore the VM. I would really like to hear from individuals in similar situations. Any and all comments and critiques are appreciated.

  • How to set up Zabbix to monitor SQL Server Failover Active-Passive Cluster?

    - by Sebastian Zaklada
    It should be simple, so it is just most likely my approach being totally off and someone will hopefully prod me into the right direction. We have a Zabbix 2.0.3 server instance set up monitoring a bunch of different servers, but now we need to set it up to monitor and notify any alerts in regards to the SQL Server 2008 R2 Failover Active-Passive cluster. Essentially, this is a 2 servers cluster, when only one of its nodes can be "active" at a given time, serving all SQL Server related requests, while the other server just "sleeps" and from the point of anyone logged on on that server - has all of the SQL Server related services in stopped state. We have tried setting up Zabbix agents on both servers, using SQL Server 2005 templates (we could not find any 2008 specific ones and the 2005 ones always seemed to be working just fine for monitoring 2008 R2 instances) and configuring Zabbix server for both of the servers, but we end up having constant alerts for the server being currently the passive one in the cluster. We have been able to look up various methods of actually monitoring the failover, but we have not been able to find any guidance in regards to how to instruct Zabbix, that in this particular case, only one of the servers in the group is expected to be in the online state, while the other can be just discarded and should not raise any alerts. I hope I made myself clear. Thanks for any guidance. I am out of ideas.

  • Gray Progress Bar in Macbook Boot caused by Partition Fault

    - by Konstantin Bodnya
    Here's my problem: When I try to load my macbook it shows the gray progress bar. It takes a while to fill the whole progress and after it macbook just shuts down. I tried to boot from recovery partition and run Disk Utility to repair it. Disk Utility showed my "Macintosh HD" in a gray color and failed to repair it. I thought all my data was lost, but then I tried the following: So I booted into ubunto from live usb and it successfully mounted my macintosh hd hfs+ partition. Parted shows me the following partitions on my disk: Disk /dev/sda: 500GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 20.5kB 210MB 210MB fat32 EFI System Partition boot 2 210MB 499GB 499GB hfs+ Macintosh HD 3 499GB 500GB 650MB hfs+ Recovery HD Seems legit except for FAT32 for EFI System Partition. Since all my data is okay and backed up what should I do to recover the system. I don't really want to reinstall all the system though I believe there's a command to make it allright in linux. Thank you everyone!

  • Bootable GRUB partition

    - by MA1
    I have a customized live fedora 12 USB which is working fine. What i want to do is to make a partition of my hard disk bootable so that my customized fedora can be run from hard disk. To accomplish this i did the following steps: Created a primary partition(/dev/sda2) and format it as ext3 and set it as active. Copy all the files in the live usb to /dev/sda2. Following are the live usb contents(all directories): a. boot b. EFI c. LiveOS d. syslinux Then i installed the GRUB in boot/grub Created the grub.conf in boot/grub Following are the contents of each directory in the USB: syslinux/ boot.cat isolinux.bin splash.jpg vesamenu.c32 initrd0.img ldlinux.sys syslinux.cfg vmlinuz0 LiveOS/ livecd-iso-to-disk osmin.img squashfs.img EFI/ boot/ boot.conf grub.conf boot.efi bootia32.conf bootia32.efi splash.jpg splash.xpm.gz vesamenu.c32 initrd0.img isolinux.bin isolinux.cfg vmlinuz0 boot/grub/ core GRUB files grub.conf olpc.fth Following are contents of grub.conf default=0 splashimage=/EFI/boot/splash.xpm.gz timeout 2 hiddenmenu title funLinux kernel /EFI/boot/vmlinuz0 root=live:LABEL=myFun rootfstype=auto ro liveimg quiet ssb.blacklist=1 selinux=0 vga=normal nomodeset rhgb initrd /EFI/boot/initrd0.img Now when i try to boot from the hard disk it shows the grub menu and fedora starting to load but during loading it said No root device found Boot has failed, sleeping forever So, where is the problem? what i am doing wrong?

  • How to get multipath working for Ubuntu Server 12.04

    - by mlampi
    I'm working on a project which aims to make use of Ubuntu servers running on enterprise class hardware. In our case that means IBM HS23E blade servers, QLogic 4GB fibre channel extension cards and quite old IBM DS4500 disk array with two controllers. At the moment we have fibre channel as only boot option and Ubuntu Server 12.04 installed just fine and is able to boot without multipath. I'm not a linux professional myself but in our team we have people who will understand the technical stuff. Don't let my post confuse :) The current situation is that we have only one fibre channel connection to a single disk array controller. Real life case would be of course quite different. At minimum we should have two fibre channel ports connected to two different switches and two different controllers. However, we have no idea how to set up multipath tool. Is the DM-MPIO the right software? At minimum we should be able to boot when multiple connections are available and achieve fault tolerance when any of them should be down. Since the disk array is not the latest hardware, I managed to find RDAC driver sources only for 2.6.x kernel. And we have 3.2.x. Another issue is to build a multipath.conf. The said driver sources are from IBM support and the QLogic drivers provided to Ubuntu installer are from Ubuntu site. It seems that RHEL and SLES would have near out of the box support but that is not an option for our project. Actual questions: - What is the recommended software tool for multipath for Ubuntu Server 12.04? - Is there available pre-made configurations or templates? Does it require disk array / controller specific settings or do a more generic config work? - Do you have expriences on similar setup and like to share the knowledge? I'll provide you with any additional information you might require. Thanks in advance.

  • How do I restart a Windows XP upgrade?

    - by Jason
    Is there a registry tweek to tell Windows Setup to start over? It tries to continue where it left off after I reboot. I can get to the Recovery Console. I tried to go from SP2-SP3. It failed, and I couldn't get to Safe Mode. I put in the SP1 disk (I don't have an SP2 boot disk, just the upgrade package.) It ran a couple minutes then gave me the error "the signature for windows xp professional upgrade is invalid" error code 800b0100. I rebooted to Safe Mode. I get to Safe Mode then say "Window XP Setup can't run under Safe Mode" press ok to restart. I put the SP3 disk back in, trying to get the "repair" option I didn't ever see putting in the SP1 disk, and it tried to continue the SP1 install - on the 4th step, and then gave the same signature error above. I need to get it to start over, so I can get to the repair option, to go back to SP2 (or install SP1 then add SP2 to it). Is there a registry tweek to tell Windows Setup to start over?

  • Firewall for internal networks

    - by Cylindric
    I have a virtualised infrastructure here, with separated networks (some physically, some just by VLAN) for iSCSI traffic, VMware management traffic, production traffic, etc. The recommendations are of course to not allow access from the LAN to the iSCSI network for example, for obvious security and performance reasons, and same between DMZ/LAN, etc. The problem I have is that in reality, some services do need access across the networks from time to time: System monitoring server needs to see the ESX hosts and the SAN for SNMP VSphere guest console access needs direct access to the ESX host the VM is running on VMware Converter wants access to the ESX host the VM will be created on The SAN email notification system wants access to our mail server Rather than wildly opening up the entire network, I'd like to place a firewall spanning these networks, so I can allow just the access required For example: SAN SMTP Server for email Management SAN for monitoring via SNMP Management ESX for monitoring via SNMP Target Server ESX for VMConverter Can someone recommend a free firewall that will allow this kind of thing without too much low-level tinkering of config files? I've used products such as IPcop before, and it seems to be possible to achieve this using that product if I re-purpose their ideas of "WAN", "WLAN" (the red/green/orange/blue interfaces), but was wondering if there were any other accepted products for this sort of thing. Thanks.

  • Successful login with iscsiadm on target still doesn't create block device

  • Ubuntu Wubi "drive" failure; mount drive in XP?

    - by 618034
    Hi there, I installed the Wubi distribution of Ubuntu on a separate partition (which is silly, since why do I care if Windows can still manage the partition?) a few months back; it was pretty awesome, until Linux hosed. At this point, I can get Ubuntu to boot if I try really hard through grub, but once it does start, the screen is hosed, so no dice. At this point, I'd like to wipe it all and start over, but I need to get some stuff off the "disk". The Wubi install makes this difficult, since the "disk" is a flat file on an NTFS partition. I've done just about everything I can think of — I renamed the virtual disk .iso, mounted it with VirtualCloneDrive, then used whatever magic EXT3 (EXT4?) readers I could dig up on the Internet to parse the mount — but nothing's working. Can you offer any suggestions? The "disk" is currently in D:\ubuntu\disks\root.iso. Many thanks! (I may be high-latency at the moment, apologies if I don't address follow-ups quickly)

  • Trouble cloning a Macbook Pro hard drive

    - by Mirko Froehlich
    I am trying to upgrade the 250GB hard drive in my MacBook Pro (early 2008 model) to a 750GB drive. I have connected the new drive via an external USB enclosure. The drive is recognized fine, I can format it, etc. However, every time I try to clone the drive, I am getting Input/Output errors. Before the clone operation, I have verified both the internal and the external drive using Disk Utility, and they both check out fine. After the clone operation, the external drive shows multiple "Invalid node structure" errors: I have tried two approaches for cloning the drive: Using Disk Utility, by starting from the OSX install DVD Using Carbon Copy Cloner The outcome is the same in both cases. The Carbon Copy Cloner logs show a handful of the following types of errors: rsync: mkstemp "<... an external filename ...>" failed: Input/output error (5) rsync: stat "<... an external filename ...>" failed: Input/output error (5) The actual files affected seem to be different across different runs of the application. Before the last run, I used Disk Utility to (once more) reformat the external drive and explicitly overwrite it with zeros, but this made no difference. I also tried running a surface scan in Tech Tool Pro overnight. It got about 2/3 of the way through before I had to disconnect the drive (had to take my MacBook Pro to work), but so far it didn't report any bad blocks. Assuming it scans the drive in the same order in which blocks would be allocated during actual use, it seems like if bad blocks were to blame for the clone failures, they should have been found already (given that the source drive is only 250GB). As a last attempt, I may try SuperDuper as well, although my understanding is that it uses the same underlying rsync approach as Carbon Copy Cloner, so it's unlikely to perform any better. Are there any other things I should try before I send the drive in for a replacement? Could these problems be caused by my internal drive, even though it works fine and checks out fine in Disk Utility?

  • Degraded RAID-5 array with lvm2 lost superblock and partition table

  • SSD seems dead after wakeup from Windows Sleep, BIOS stalls but doesn't find it anymore

    - by Abel
    The morning, the following scary scenario happened: I woke up my Windows system Typed in my username and got an error (something like "could not load security xxx", but unsure of exact wording) System auto-restarted after cliking OK It didn't boot up anymore to the SSD with Windows 7 OS (I have another disk I can boot to, but that doesn't see the disk either). Obviously, this happened right after I instantiated a backup procedure, which hasn't succeeded either. The BIOS can't find the drive when I connect to SATA. And it can't find the drive when I connect it to SAS. I have a Dell Workstation T7400, most recent BIOS (version A06), version of SAS Host Bus Adapter BIOS (HBA) is MPTBIOS 6.14.10.00 (2007.09.29) from LSI Logic Corp. Other findings: When connecting to SATA, the DELL Logo screen stays really long (5 minutes) and then at the end of POST it says that a drive is not found When connecting to SAS, the SAS HBA initializing phase takes long (2 minutes, against normally 15 seconds) When running Dell Diagnostics, it doesn't finish and gives the error Exception occurred in module MPCACHE.MDM file "IOAPICSP.ASM" line 1645. I contacted Dell. On their advice I tried different slots and different cables to no avail. I use an APIC battery power, spikes in the power are thus unlikely. My conclusion so far: the disk is dead. I need this disk very badly because it contains the last few days of important development of which not all code was checked in the moment this happened. Are there any ways to recover dead SSD drives? The drive is a new X25-M G2 160GB model SSDSA2M160G2GC 2.5" in an extension bay and has been running without issues for 3 months on SAS.

  • Can I format a Veritas cluster shared volume from windows?

    - by spaghettidba
    We have a Microsoft Failover Cluster with dynamic disks managed by Veritas Storage Foundation. Today the sysadmins added a new disk for SQL Server but the cluster size on the volume was wrong, so I issued a quick format to change it. The disk volume failed, the SQL Server group failed as well and the cluster became unresponsive. After some minutes I managed to fail over to a passive node. The SAN admins say it's my fault because I shouldn't have formatted the disk from the Windows format applet, but I should have used Veritas Enterprise Administrator instead. Can a format operation bring offline a whole cluster group this way? Relevant error messages: From the eventlog: The cluster resource host subsystem (RHS) stopped unexpectedly. An attempt will be made to restart it. This is usually due to a problem in a resource DLL. Please determine which resource DLL is causing the issue and report the problem to the resource vendor. From the cluster.log ERR [RCM] rcm::RcmResControl::DoResourceControl: ERROR_RESOURCE_CALL_TIMED_OUT(5910)' because of 'Control(STORAGE_GET_DISK_INFO_EX) to resource 'NameOfTheDiskGroup' timed out.' Veritas Documentation: Excerpt from Symantec's documentation: Note: Before manually creating the resource, you must format the cluster-shared volume with NTFS using the VEA GUI and mount it on the node where you are trying to create the resource. Does this mean the disk cannot be formatted from Windows? I don't read it that way. For the record, I formatted many disks using the Windows applet in the past and nothing bad happened.

  • What to do with a broken OS X install disc?

    - by slhck
    First things first: I don't appreciate software piracy and I really want to spend money on software that I use and that I work and make money with. I don't want this question closed just because I consider downloading software, I only want honest opinions and alternatives. Here we go: So I have my OS X Snow Leopard Upgrade DVD, but it's horribly scratched and won't boot anymore. It endlessly loads and at some point I have to force pull it out of the disc slot. How can I reset my Mac then? Can I take my original disk to an Apple Store and ask them for a replacement? Will they believe me, even if I don't have the receipt anymore? Would owning the original disk make it okay for me to look somewhere on the internet and download it? I don't even know if that will work without hassles. Could I try to read the disk to an image with some error correction methods? Maybe during boot it can't read some files, but some other program can? Is there any other way of resetting the Mac? Mine's now over 3 years old an I seem to have misplaced my original discs that had 10.4 on it. Or should I just buy a new 10.6 upgrade disk? (Which is not really what I want to do) Answers and opinions would be much appreciated.

  • RAID6 mdraid -> LVM -> EXT4 root with GRUB2?

    - by Rotonen
    2012-03-31 Debian Wheezy daily build in VirtualBox 4.1.2, 6 disk devices. My steps to reproduce so far: Setup one partition, using the entire disk, as a physical volume for RAID, per disk Setup a single RAID6 mdraid array out of all of those Use the resulting md0 as the only physical volume for the volume group Setup your logical volumes, filesystems and mount points as you wish Install your system Both / and /boot will be in this stack. I've chosen EXT4 as my filesystem for this setup. I can get as far as GRUB2 rescue console, which can see the mdraid, the volume group and the LVM logical volumes (all named appropriately on all levels) on it, but I cannot ls the filesystem contents of any of those and I cannot boot from them. As far as I can see from the documentation the version of GRUB2 shipped there should handle all of this gracefully. http://packages.debian.org/wheezy/grub-pc (1.99-17 at the time of writing.) It is loading the ext2, raid, raid6rec, dosmbr (this one is in the list of modules once per disk) and lvm modules according to the generated grub.cfg file. Also it is defining the list of modules to be loaded twice in the generated grub.cfg file and according to quick Googling around this seems to be the norm and OK for GRUB2. How to get further by getting GRUB2 to actually be able to read the content of the filesystems and boot the system? What am I wrong about in my assumptions of functionality here? EDIT (2012-04-01) My generated grub.cfg: http://pastie.org/3708436 It seems it first makes my /usr logical volume the root and that might be source of the failure? A grub-mkconfig bug? Or is it supposed to get access to stuff from /usr before / and /boot? /boot is on / for me - no separate boot logical volume.

  • iMac 20inch (Mid 2007) SL DVD Boot Prohibitory Sign

    - by Caitlann Lloyd
    iMac 20inch (Mid 2007 Build) with Ubuntu 12.0.4 How I got in this situation I had a perfectly healthy Intel iMac running Snow Leopard several months ago. Then I got the dreaded spinning gear and several kernel panics. After getting a little frustrated (failing to find a solution online), I found an old macbook installation disk and used it to access Disk Utility. From here, I erased my entire hard drive leaving me with no OS. I then created a Ubuntu DVD and installed Ubuntu onto the system. Now, on Ubuntu, I wine installed Transmac and burned a Single layer copy (with languages, etc. removed to save space) of Snow Leopard onto a 4.7GB DVD. I tried to boot from it and was met with first the grey apple screen and a spinning cog before the grey apple shortly turned into the infamous prohibitory sign. Note: I met this problem previously when using Disk Utility to create a bootable USB of Snow Leopard, hence I severely doubt it has anything to do with the DVD created. Resources at my disposal 1 x iMac running Ubuntu 6 x 4.7GB DVDs 1 x USB Stick 12GB 1 x Windows 7 Laptop Resources I do not have Firewire cables Access to a prebuilt retail disk (Misplaced) Access to another Mac Apple Warranty I would be hugely grateful if someone was able to tell me how to install Snow Leopard again.

  • Update a bootable OS X drive clone with rsync?

    - by Joe
    The question: is it possible to keep a boot-able backup drive clone of OS X updated with rsync? If rsync is not a viable option are there alternatives? The Setup: My situation is as shown above. One internal Samsung 840 SSD [120g] in use as my OS X 10.8 boot disk on a recent model Mac Mini. I have successfully cloned that drive with disk utility to a 125g partition of another HDD in an external USB 3 enclosure and at that point I am able to boot to it. The Goal: As my last system went out in a fiery blaze taking much valuable data with it, I have a new respect for a proper backup solution and really want to do this right. My goal is to achieve an automated differential backup/update from Disk A to Disk B while most importantly maintaining boot-ability on the external drive. And I would prefer to do this differentially to minimize stress on the drives. Hence rsync was the first thing to come to mind. What I have tried: following along with Jamie Zawinski's differential mac bootable backup solution running this manually initially worked - i tested it with only very miniscule file change and everything was fine / external booted and all. now after subsequent passes rsync fails throwing errors particularly relating to updating 'boot.efi' (not at the machine currently I will update the precise log message once I return home) is this a drive partition size issue? does rsync require more space? if it cant be done, are there any alternatives? i've heard whispers of dd

  • How do I find my missing songs from last.fm?

    - by duality_
    My disk failed with all my music with it, lots of them. But luckily, I scrobbled every song to last.fm. I am looking for a way to scan my disk for my songs and check last.fm and tell me which songs are missing from my disk that are present on last.fm. So to recap: I would need to log into my last.fm account and compile a list of all the songs I have scrobbled and then scan my computer for missing songs. Is there a program or script that does this? I don't mind it being a shell script even. Edit: I know this is possible because I came close to this a little time ago. I created a PHP script (web page) that got all my songs through Last.fm API and then went through my files on disk and read their id3 tag. I got very close: the program showed missing songs, but there were many small issues (id3 reading was buggy, tags had different data, etc.) that required more programming time that I didn't have.

  • Ubuntu 12.04/12.10 can't detect windows or any other partitions(Asus z77 UEFI BIOS)

    - by user971155
    I've recently completed tinkering my new pc(motherboard ASUS z77 with UEFI BIOS) and unfortunately not everything works quite well. After installing windows 7 ultimate on a single primary partition(SATA drive) I decided to allocate one more logical partition for additional needs. When I tried doing it with the manager - it said that it couldn't allocate requested size even though I certainly asked for much less than it was available. I thought that it might have been a windows issue and proceded to installing Ubuntu 12.10 x64. When the graphical interface loaded it showed me a message stating that it can't find any other operating system on the drive. When I used custom partioning option it showed me none of my current partions(including that with windows). However, when I boot with "Try Ubuntu" feature it does find them ! I find it weird though. Here's what the console present me with: ubuntu@ubuntu:~$ sudo os-prober /dev/sda1:Windows 7 (loader):Windows:chain ubuntu@ubuntu:~$ sudo fdisk -l Disk /dev/sda: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders, total 1250263728 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00072b98 Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 206848 100020223 49906688 7 HPFS/NTFS/exFAT /dev/sda3 100022270 1250263039 575120385 5 Extended /dev/sda4 566669312 1250263039 341796864 83 Linux I also tried creating partitions from disk utility which results in error: , Error creating partition: helper exited with exit code 1: In part_add_partition: device_file=/dev/sda, start=51211402240, size=1923000000, type=0x83 Entering MS-DOS parser (offset=0, size=640135028736) MSDOS_MAGIC found looking at part 0 (offset 1048576, size 104857600, type 0x07) new part entry looking at part 1 (offset 105906176, size 51104448512, type 0x07) new part entry looking at part 2 (offset 51211402240, size 588923274240, type 0x05) Entering MS-DOS extended parser (offset=51211402240, size=588923274240) readfrom = 51211402240 MSDOS_MAGIC found Exiting MS-DOS extended parser looking at part 3 (offset 290134687744, size 349999988736, type 0x83) new part entry Exiting MS-DOS parser MSDOS partition table detected containing partition table scheme = 1 got it Error: Can't have overlapping partitions. ped_disk_new() failed Here's what I get when I try to install the system i.stack.imgur.com/pjlb9.png, i.stack.imgur.com/g1lXN.png P.S. It's strange that I even can't create any more partitions neither with disk-utility nor with windows 7 native tools

  • Accidentally dd'ed an image to wrong drive / overwrote partition table + NTFS partition start

    - by Kento Locatelli
    I screwed up and set the wrong output for dd when trying to copy a freenas iso, overwriting the wrong external hard drive. Ironically, I was trying to setup a freenas server for data backup... External drive is only used for data storage, system is entirely intact Drive had a single NTFS partition filing the entire device (2TB WD elements) Drive originally had an MBR partition table. Drive now shows as having a GPT, presumably from the freenas image. Drive was mounted at the time, with maybe a couple kB of data written/read after running dd Drive is just a few months old and healthy (regular SMART / fs checks) I have not reboot the OS (crunchbang) /proc/partition still holds the correct information (and has been stored) Have dd's output (records in / out / bytes) testdrive did not find any partitions on quick or deep search running photorec to recover the more important data (a couple recent plaintext files that hadn't been backed up yet). Vast majority of disk content ( 80%) is unnecessary media files. My current plan is to let photorec do it's thing, then recreate the mbr with gparted and use cfdisk to create another NTFS partition using the sector information from /sys/block/.../. Is that a good course of action (that is, a chance of success)? Or anything else I should try first?

  • Should an HA failover occur in this scenario?

    - by joeqwerty
    I'm running vSphere 5 in an HA cluster across two hosts (vsphereA and vsphereB). I have the HA cluster configured for host monitoring and datastore heartbeat monitoring with admission control disabled (hopefully I rightfully understand that datastore heartbeat monitoring prevents inadvertent and unwanted HA failovers due to management network isolation). Each host has a single connection to a dedicated iSCSI network and iSCSI target (no MPIO). All vmdk's for all VM's exist on the iSCSI datastore. As a test of HA I disconnected the iSCSI connection on vsphereB and was surprised to see that the running VM's on vsphereB continued to run on vsphereB. The powered off VM's were showing as inaccessible (which I expected due to the fact that they weren't running and the connection from vsphereB to the iSCSI target was severed) but the running VM's continued to run and continued to be "owned" by vsphereB. I expected to see an HA failover occur for those VM's and expected to see them "owned" by vsphereA after the HA failover (which didn't occur). I'm at a loss to understand why an HA failover didn't occur for those VM's. Am I misunderstanding in which cases an HA failover should occur?

  • why does the partition start on sector 2048 instead of 63

    - by gcb
    I had two drives partitioned the same and running 2 raid partitions on each. One died and I replaced it under warranty for the same model. While trying to partition it, the first partition can only start on sector 2048, instead of 63 that was before. Driver have different geometry as previous and remaining ones. (Fewer heads/more cylinders) old drive: $ sudo fdisk -c -u -l /dev/sdb Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000aa189 Device Boot Start End Blocks Id System /dev/sdb1 * 63 174080339 87040138+ 83 Linux /dev/sdb2 174080340 182482334 4200997+ 82 Linux swap / Solaris /dev/sdb3 182482335 3907024064 1862270865 fd Linux raid autodetect remanufactured drive received from warranty: $ sudo fdisk -c -u -l /dev/sda Disk /dev/sda: 2000.4 GB, 2000398934016 bytes 81 heads, 63 sectors/track, 765633 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000d0b5d Device Boot Start End Blocks Id System /dev/sda1 2048 ... why is that?
