• Dual booting windows 8/ubuntu 12.04. Grub doesn't appear and machine never boot in ubuntu

  - by black sensei

  i got a new ACER predator AG3620-UR308 which came with windows 8, so i wanted to run ubuntu 12.04.2 on it as a dual booting. To be honest, i've been doing dual booting for a while now so, i did the right thing. the box came with 2TB HDD. so i made 4 partitions with a raw partition just after the windows installation partition I always do manual installation so even if ubuntu didn't detect windows 8, it was ok for me. So i created swap area and finished the installation etc....Grub was install on the only drive there which is sda. After reboot, grub doesn't even come up.So it always boot in windows 8. I did repeat the installation process twice and yield same result. which is weird because this method always works for me so far.Even the laptop am using to write this post is a dual booting windows 7/ mint nadia installed the same way. Is there anything new in windows 8 that i didn't make provision for? Before starting the installation, all i read about was that , windows 8 should be installed first and ubuntu after. I went ahead and disable secure boot from the BIOS and enabled CSM (don't even know what it means) according to Acer custhelp site . I boot from USB and did fdisk -l bellow is the result: ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

• Weird Ubuntu Desktop Boot Partition On External Hard Drive

  - by Magnitus

  I have a Thinkpad with Windows 7. Last time I installed an Ubuntu/Windows dual boot, Windows was never same after and regularly got corrupted so this time, I installed Ubuntu on a separate external hard drive. I took a 500 GB external hard drive and used Windows to shrink the partition on it to 400 GB, freeing 100 GB to install Ubuntu. Then I modified the booting priority of my computer to boot from the external hard drive if present. Then, I installed Ubuntu desktop on the external hard drive using a DVD, picked the most simplistic partitioning scheme I could get away with (didn't go auto as it didn't include the external hard drive as a choice) and voilà. Fast forward some time and I'm trying to refresh my understanding of Linux partitions to install a bunch of servers, so I'm looking at the current partitioning scheme on my external hard drive and find the boot partition puzzling... sda is my integrated hard drive with Windows 7. sdb is my Ubuntu desktop external hard drive. Running parted on sdb, I get this: (parted) print Model: WD My Passport 0740 (scsi) Disk /dev/sdb: 500GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 393GB 393GB primary ntfs boot 2 393GB 500GB 107GB extended 5 393GB 425GB 32.8GB logical linux-swap(v1) 6 425GB 500GB 74.6GB logical ext4 At this point, I'm wondering why the ntfs partition is flagged as "boot" and not my ext4 partition which is the partition that contains / (and by extension, /boot since it's not on its own separate partition). Looking at mtab only confirms what I already know: eric@eric-ThinkPad-W530:~$ sudo cat /etc/mtab /dev/sdb6 / ext4 rw,errors=remount-ro 0 0 proc /proc proc rw,noexec,nosuid,nodev 0 0 sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0 none /sys/fs/cgroup tmpfs rw 0 0 none /sys/fs/fuse/connections fusectl rw 0 0 none /sys/kernel/debug debugfs rw 0 0 none /sys/kernel/security securityfs rw 0 0 udev /dev devtmpfs rw,mode=0755 0 0 devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=0620 0 0 tmpfs /run tmpfs rw,noexec,nosuid,size=10%,mode=0755 0 0 none /run/lock tmpfs rw,noexec,nosuid,nodev,size=5242880 0 0 none /run/shm tmpfs rw,nosuid,nodev 0 0 none /run/user tmpfs rw,noexec,nosuid,nodev,size=104857600,mode=0755 0 0 none /sys/fs/pstore pstore rw 0 0 systemd /sys/fs/cgroup/systemd cgroup rw,noexec,nosuid,nodev,none,name=systemd 0 0 gvfsd-fuse /run/user/1000/gvfs fuse.gvfsd-fuse rw,nosuid,nodev,user=eric 0 0 /dev/sdb1 /media/eric/My\040Passport fuseblk rw,nosuid,nodev,allow_other,default_permissions,blksize=4096 0 0 My lack of understanding concerning this is not vital to anything (this is only my development desktop partition), but somehow annoys me. Any insight that could shed some light on this would be welcome.

• How to manage and capture database changes across several developers?

  - by Matt Greer

  We have three developers and one tester all working against the same database. We change the schema of the database quite often, and every time we do it tends to have a ripple effect of headaches for everyone else. Are there good practices in place for .NET oriented development against MS SQL Server 2008 for managing this? I am thinking something similar to Rails Migrations and each dev and tester has their own local database. Or is that overkill? It'd at least be nice to have separate test and dev databases, but currently manually keeping two databases in sync is probably worse than our current predicament. LiquiBase seems promising, has anyone successfully used it in a similar environment? Or are there better approaches? We are using SQL Server 2008, VS 2008 and .NET 3.5 if that matters at all.

• Terminal Colors Not Working

  - by Matt Fordham

  I am accessing an Ubuntu 10.04.2 LTS server via SSH from OSX. Recently the colors stopped working. I think it happened while I was installing/troubleshooting RVM, but I am not positive.

• How do I stop and repair a RAID 5 array that has failed and has I/O pending?

  - by Ben Hymers

  The short version: I have a failed RAID 5 array which has a bunch of processes hung waiting on I/O operations on it; how can I recover from this? The long version: Yesterday I noticed Samba access was being very sporadic; accessing the server's shares from Windows would randomly lock up explorer completely after clicking on one or two directories. I assumed it was Windows being a pain and left it. Today the problem is the same, so I did a little digging; the first thing I noticed was that running ps aux | grep smbd gives a lot of lines like this: ben 969 0.0 0.2 96088 4128 ? D 18:21 0:00 smbd -F root 1708 0.0 0.2 93468 4748 ? Ss 18:44 0:00 smbd -F root 1711 0.0 0.0 93468 1364 ? S 18:44 0:00 smbd -F ben 3148 0.0 0.2 96052 4160 ? D Mar07 0:00 smbd -F ... There are a lot of processes stuck in the "D" state. Running ps aux | grep " D" shows up some other processes including my nightly backup script, all of which need to access the volume mounted on my RAID array at some point. After some googling, I found that it might be down to the RAID array failing, so I checked /proc/mdstat, which shows this: ben@jack:~$ cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid5 sdb1[3](F) sdc1[1] sdd1[2] 2930271872 blocks level 5, 64k chunk, algorithm 2 [3/2] [_UU] unused devices: <none> And running mdadm --detail /dev/md0 gives this: ben@jack:~$ sudo mdadm --detail /dev/md0 /dev/md0: Version : 00.90 Creation Time : Sat Oct 31 20:53:10 2009 Raid Level : raid5 Array Size : 2930271872 (2794.53 GiB 3000.60 GB) Used Dev Size : 1465135936 (1397.26 GiB 1500.30 GB) Raid Devices : 3 Total Devices : 3 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Mon Mar 7 03:06:35 2011 State : active, degraded Active Devices : 2 Working Devices : 2 Failed Devices : 1 Spare Devices : 0 Layout : left-symmetric Chunk Size : 64K UUID : f114711a:c770de54:c8276759:b34deaa0 Events : 0.208245 Number Major Minor RaidDevice State 3 8 17 0 faulty spare rebuilding /dev/sdb1 1 8 33 1 active sync /dev/sdc1 2 8 49 2 active sync /dev/sdd1 I believe this says that sdb1 has failed, and so the array is running with two drives out of three 'up'. Some advice I found said to check /var/log/messages for notices of failures, and sure enough there are plenty: ben@jack:~$ grep sdb /var/log/messages ...

I cannot hot-swap a replacement drive in, and don't want to leave the array running in a degraded state. I believe I am supposed to unmount the filesystem before stopping the array, but that is failing, and that is where I'm stuck now: ben@jack:~$ sudo umount /storage umount: /storage: device is busy. (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1)) It is indeed busy; there are some 30 or 40 processes waiting on I/O. What should I do? Should I kill all these processes and try again? Is that a wise move when they are 'uninterruptable'? What would happen if I tried to reboot? Please let me know what you think I should do. And please ask if you need any extra information to diagnose the problem or to help!

• Vista Power Management GPO

  - by Matt

  Hi, I've created a loopback GPO that has several settings (both computer and user) including a Custom User Interface (Access 2007 Application) and Power Management (has the computer sleep after being idle for 2 min). I'm also filtering so that this policy does not apply to "Admins" - only to "Users". The problem I'm having is when the "Users" login the Power Management settings don’t work, but they do for "Admins". For testing I'm allowing the "Users" to launch Task Manager and use the Run line, so I'll run Explorer and look at Power Management and it shows the settings from my GPO. So I created a test OU with copies of the aforementioned GPO, but removed the Custom User Interface and found the Power Management settings do work for both the "Users" and "Admins". When I add the Custom UI the Power Management settings break for the "User" but continue to work for "Admins". Do the Power Management options need to have User Interface be "Explorer.exe"? Is this a bug or am I doing this the wrong way? BTW the tablets are using Vista SP2. Any insight or advice would be greatly appreciated. Thanks, Matt

• Heartbeat won't successfully start up resources from a cold boot when a failed node is present

  - by Matthew

  I currently have two ubuntu servers running Heartbeat and DRBD. The servers are directory connected with a 1000Mbps crossover cable on eth1 and have access to an IP camera LAN on eth0. Now, let's say that one node is down and the remaining functional node is booting after having been shut down. The node that is still functioning won't start up heartbeat and provide access to the drbd resource from a cold boot. I have to manually restart heartbeat by sudo service heartbeat restart to get everything up and running. How can I get it to start fine from a cold start, when only one server is present?

  This is a followup question to Cannot mount /dev/sdc1 on Debian 5.0, special device /dev/sdc1 doesn't exist Basically, I have 6 SATA hard drives in a machine and I'm trying to create a RAID6 array with them. When I try to run the mdadm command to create (with the verbose option) a raid array, I see messages like "mdadm: super1.x cannot open /dev/sdf1: No such device or address" which are resolved by doing partprobe /dev/sdf and then re-running the mdadm command. The problem is that I have to run partprobe after each reboot, and from experience I don't think this is normal behaviour -- on no other linux machine do I have to partprobe the device before I can use it. Something must be going wrong, but how do I troubleshoot this to find out what? Could this be caused by a hardware problem? Edit: Additional note - before I seemed to only have this problem with one drive, but now I'm having it with 3 drives.

• Linux partitioning problem

  - by Claudiu

  I am using cfdisk to repartition my hdd as from OS install I only got 1 big partition a swap. I wanted to resize the big partition to 1 GB /boot and use the rest of the space for an extended partition. After I do cfdisk, I recheck the partitions with fdisk -l and I get these: Disk /dev/sda: 320 GB, 320070320640 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda3 1 38455 308881755 f Extended LBA Warning: Partition 3 does not end on cylinder boundary. /dev/sda2 38455 38698 1951897 82 Linux swap /dev/sda1 * 38699 38913 311349654 83 Linux My problem is the Warning message, I think I know the cause, I think its because of sda1 Blocks size. How could that be soo big if Start and End interval is small?

• Ubuntu NBR karmic boot freezes at fsck from util-linux-ng 2.16

  - by BlueBill

  Hi all, I have a netbook (emachine e250 - equivalent to an acer aspire one) and I have Ubunutu NBR 9.10 installed on it. Every other cold boot freezes at the following error message: "fsck from util-linux-ng 2.16" There is no disk activity, no activity what so ever. I have left the machine sit for over an hour and nothing. It takes a couple of hard resets to be able to boot properly. Once it boots everything works great (wireless, suspend/resume, etc.)! I have spent the last couple of weeks researching the problem and the only thing that seems to work is setting nolapic in the boot string in grub - it boots every time. Unfortunately, nolapic disables the second core and causes problems with suspend resume. At first I thought it was an fsck problem with the first partition on the hard disk as it is a hidden ntfs partition containing the windows xp recover information. So in /etc/fstab I set the partition so that it would be ignored by fsck. This didn't seem to do anything. I have these partitions: /dev/sda1 - an ntfs recovery partition /dev/sda2 - /boot /dev/sda3 - swap /dev/sda5 - / /dev/sda6 - /home I am running kernel version 2.6.31-19-generic and have all the patches (as indicated by update manager). I also have no splash screen so I can see the boot progress. I have only been using NBR since January, I have been using Ubuntu on my desktop since last June (2009-06). What logs should I be looking at? Is there a log for failed boots? Thanks, Troy

• AWS Large Instance: /mnt does not show all the space that should be available

  - by Emile Baizel

  I just created a Large (m1.large) 64 bit instance which comes with 850 GB instance storage. Look at the Large Instance http://aws.amazon.com/ec2/instance-types/ A 'df -h' from the root folder gives me the output below. The /mnt is where I'm thinking the instance storage is but here it is only showing me 414G. I have set up two servers and both are showing the same numbers. root@ip-11-11-11-11:/# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.9G 1.1G 6.5G 14% / none 3.7G 112K 3.7G 1% /dev none 3.7G 0 3.7G 0% /dev/shm none 3.7G 48K 3.7G 1% /var/run none 3.7G 0 3.7G 0% /var/lock /dev/sdb 414G 199M 393G 1% /mnt

• How to reinstall Mac OS X on OS X/Linux dual-boot system?

  - by strangeronyourtrain

  My setup: I have a MacBook Pro 5,5 with a Mac OS X Snow Leopard partition and a Linux partition. I use rEFIt to boot into Linux. I didn't use Boot Camp when I originally installed Linux; instead, I manually created the partition (with either Disk Utility in OS X or Gparted on a Linux live CD--I don't recall which one) and then installed Linux on it from a live CD. The problem: My OS X partition is corrupt, and I need to reinstall Snow Leopard. Since I installed rEFIt from within OS X, I'm concerned that wiping the OS X partition will prevent me from booting into my Linux partition. How can I do this without losing access to my Linux partition? Is it possible to install Snow Leopard on the partition I reserved for it, or will it automatically overwrite the entire drive? And if I do the fresh OS X install and then install rEFIt again, will it automatically recognize my Linux partition? Thanks for any tips! Specs: MacBook Pro 5,5 (Mid-2009); Snow Leopard 10.6.7/64-bit Sabayon Linux, 2.6.36 kernel EDIT/UPDATE: Thanks, but the situation has taken a more complicated turn: I tried to reinstall Snow Leopard from the DVD, but it refused to install onto my Mac partition, claiming: "The disk cannot be used to start up your computer." Disk Utility wouldn't let me resize the partition or create a new one, and it doesn't see my Linux partition. It only displays the two partitions "Macintosh HD" and Linux Swap. I can, however, see all the partitions from Linux. This is the partition table as shown in Gparted: And the output of "fdisk -l" is: WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders, total 488397168 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: 0x00000000 Device Boot Start End Blocks Id System /dev/sda1 1 409639 204819+ ee GPT /dev/sda2 409640 349590464 174590412+ af HFS / HFS+ /dev/sda3 483122745 488392064 2634660 82 Linux swap / Solaris /dev/sda4 * 349590465 483122744 66766140 83 Linux Partition table entries are not in disk order I wonder if this is because I originally partitioned my disk with Gparted instead of OS X's Disk Utility (at this point, I don't recall whether I used Gparted or Disk Utility). In any case, it doesn't seem safe to do any reformatting with Disk Utility now, as I'm afraid it will wipe sda2 ("Macintosh HD") as well as sda4 (my Linux partition). So... I'm hoping to find a solution that doesn't involve wiping my entire hard disk. Would it be safe/possible to use Gparted to erase sda2 ("Macintosh HD") and then use the Snow Leopard DVD to install OS X onto [I]just[/I] sda2 without touching the other partitions? Thanks for any insight!

• smartctl not actually running self tests?

  - by canzar

  I want to run the smartctl self tests to check the health of the drives in my RAID array (PERC 5/i). The array is on sda and comprises six drives. I can check the status using sudo smartctl /dev/sda -d megaraid,0 -a And I see that SMART is available and enabled on all the drives. I have tried to run self tests using sudo smartctl /dev/sda -d megaraid,0 -t short and sudo smartctl /dev/sda -d megaraid,0 -t long I have also tried it on all of the drives 0-5. No matter what I try, when I run: sudo smartctl /dev/sda -d megaraid,0 -l selftest I always get the same result, which seems to always report that I have never run a self test. /dev/sda [megaraid_disk_00] [SAT]: Device open changed type from 'megaraid' to 'sat' ===START OF READ SMART DATA SECTION === SMART Self-test log structure revision number 1 No self-tests have been logged. [To run self-tests, use: smartctl -t] From what I read, I should have no problem running the short and long self tests on the array while it is mounted. Does anyone else have experience running these tests on a PERC 5/i raid array who could lend some insight into what is causing the problem?

• How to create a Windows 7 installation usb media from linux ? (to install Windows 7) - Help need to know better method

  - by Abel Coto

  I have been reading some web pages and posts here and in other forums about how to create a Windows 7 installation Usb media (to install windows 7 using a usb) from linux. I asked in technet about this , and they give me general ideas about how to do it I personally am not very familiar with linux, but basicaly all that you need to do... in whatever way you do it is the following: Format a usb flash drive, either fat32 or ntfs create a partition that is large enough to host the windows installation (give or take 3GB for 64bit, aroudn 2.5gb for 32bit) and mark that partition as active/bootable. Since this can be done with windows, but just as well with a tool like gparted, you should be able to do the same in debian. Once you have created that partition, mount the iso that you download, and copy all files starting from the root, into the root of the usb flash drive. That's all there's to it. There is a method that i found in various places,that is almost the same that the man of technet has said. But,there is a step,that in that method is done,that i don't know if it is really necessary,or not. Not allways dd works.Basically, the missing step was to write a proper boot sector to the usb stick, which can be done from linux with ms-sys. This works with the Win7 retail version. Here is the complete rundown again: Install ms-sys Check what device your usb media is asigned - here we will assume it is /dev/sdb. Delete all partitions, create a new one taking up all the space, set type to NTFS, and set it bootable: *# cfdisk /dev/sdb* Create NTFS filesystem: *# mkfs.ntfs -f /dev/sdb1* Mount iso and usb media: *# mount -o loop win7.iso /mnt/iso # mount /dev/sdb1 /mnt/usb* Copy over all files: *# cp -r /mnt/iso/* /mnt/usb/* Write Windows 7 MBR on usb stick: *# ms-sys -7 /dev/sdb* ...and you're done. Shouldn't the usb work without doing the last step "# ms-sys -7 /dev/sdb" or to make the usb bootable , is a must , not only to mark the partition as bootable ? Would be better use rsync instead of cp -r ? All this steps should be done as root, i suppose , or if not , chmod to 664 and chown the directories where are mounted the usb and the iso, no ? But i suppose that the easier thing is to copy the data as root , and that this will not affect to the data. Has anyone tried this method or some similar like copying the iso with dd ?

• Why do I get xfs_freeze "Operation not supported" error with ec2-consistent-snapshot? Debian Squeeze w/ext4 filesystem

  - by Michael Endsley

  I'm running the following command: [root@somehost ~]# ec2-consistent-snapshot --aws-credentials-file '/some/dir/file' --mysql --mysql-socket '/var/run/mysqld/mysql.sock' --mysql-username 'backup' --mysql-password 'password' --freeze-filesystem '/dev/xvda1' vol-xxxxxx It returns this error: xfs_freeze: cannot freeze filesystem at /dev/xvda1: Operation not supported ec2-consistent-snapshot: ERROR: xfs_freeze -f /dev/xvda1: failed(256) snap-eeb66393 xfs_freeze: cannot unfreeze filesystem mounted at /dev/xvda1: Invalid argument ec2-consistent-snapshot: ERROR: xfs_freeze -u /dev/xvda1: failed(256) This is being run on Debian Squeeze with the ext4 Linux filesystem. Can anyone explain this error to me, or what might be its cause? When googling, I found information about it needing to be executed with sudo, but I'm performing the entire operation as root. I also found some posts about trying to run it after a CentOS upgrade using yum, but the situation appeared dissimilar. It's difficult to find things referring to this situation exactly. xfs_freeze is available for use on the filesystem. Is it possible that the filesystem, despite being ext4, somehow doesn't support freezing? Sorry if I've missed some bit of StackExchange etiquette with this post -- it's my first venture here!

• How do I usb tether my Cyanogen modded G1's internet connection to my Toshiba Tecra 8000 running Xub

  - by atticus

  I have usb-tethering enabled in my phone. It works fine with Vista. When I plug my phone into my Tecra 8000 laptop running Xubuntu, dmesg shows: "usb 1-1: new full speed USB device using uhci_hcd and address 8". I see that the OS has detected it as a storage device, but I can't get it to function correctly as a network device. /dev/us* shows no usb0, but it does show /dev/usbdev1.1_ep00 /dev/usbdev1.1_ep81 /dev/usbdev1.8_ep00 ... usbdev1.8_ep83. I could just use the wireless tether app for android, but I can't get my Netgear wg511 v2 (made in China) wireless card to work in this laptop either. But that's another post for later.

• Can't manage iPod from linux anymore

  - by kemp

  I used to be able to see and manage my iPod with different softwares: Amarok, Rhythmbox, GTKPod. The device is a nano 1st generation 4gb. Currently it mounts regularly and can be accessed from the file system, but I get this in dmesg: [ 1547.617891] scsi 11:0:0:0: Direct-Access Apple iPod 1.62 PQ: 0 ANSI: 0 [ 1547.619103] sd 11:0:0:0: Attached scsi generic sg2 type 0 [ 1547.620478] sd 11:0:0:0: [sdb] Adjusting the sector count from its reported value: 7999488 [ 1547.620494] sd 11:0:0:0: [sdb] 7999487 512-byte hardware sectors: (4.09 GB/3.81 GiB) [ 1547.621718] sd 11:0:0:0: [sdb] Write Protect is off [ 1547.621726] sd 11:0:0:0: [sdb] Mode Sense: 68 00 00 08 [ 1547.621732] sd 11:0:0:0: [sdb] Assuming drive cache: write through [ 1547.623591] sd 11:0:0:0: [sdb] Adjusting the sector count from its reported value: 7999488 [ 1547.624993] sd 11:0:0:0: [sdb] Assuming drive cache: write through [ 1547.625003] sdb: sdb1 sdb2 [ 1547.629686] sd 11:0:0:0: [sdb] Attached SCSI removable disk [ 1548.084026] FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

[ 1610.092886] usb 2-6: USB disconnect, address 9 The only application that can access it (partially) is Rhythmbox. I say partially because I can transfer files to the iPod but can't remove or modify them. Also one transfer didn't finish and only 9 out of 16 songs were delivered to the device. All other softwares I tried (GTKPod, Amarok, Songbird) don't even detect it. What can I do to troubleshoot this?

Haven't been using my iPod for a while so I can't say when exactly it stopped working. I'm sure Amarok was still at version 1.X but can't remember when it was. My current system is debian testing fully updated. NOTE: just noticed that if I mount the device manually instead of letting nautilus automount it, I can see it again on GTKPod but still not on Banshee AND it's vanished from Rhythmbox...
