Ubuntu Installation :: Desperate: Upgrade From 10.4 64-bit To 10.10 - Won't Boot From Raid

Dec 2, 2010

I upgraded my Dell T3500 from lucid64 to maverick64. The system cannot boot the current image becuase it gives up waiting for root device. it gives something like:

Code: ---udevd-work[175]: '/sbin/modprobe -bv pci: v00008086d00002822sv00001028s00000293bc01sc04i00' unexpected exit with status 0x0009 ALRT! /dev/mapper/isw_bbfcjjefaj_ARRAY01 does not exist. dropping to a shell! at which point it drops to busybox at the (initramfs) prompt. I cannot boot this kernel in either normal or recovery mode (ubuntu 10.10, Kernel 2.6.35-23-generic)

however, if I select the previous kernel in grub, (2.6.32-26) it will boot fine. This is my main production machine and it hosts my Project Management software for my team.

Fedora Installation :: F12 Won't Boot On LVM/RAID System After Upgrade

Dec 9, 2009

I upgraded from F10 to F12 using preupgrade. The upgrade itself completed with no errors, but I'm unable to boot afterward.

Symptoms:...Grub starts, the initramfs loads, and the system begins to boot. After a few seconds I get error messages for buffer i/o errors on blocks 0-3 on certain dm devices (usually dm0 and dm2, but I can't get a shell to figure out what those are). An error appears from device-mapper that it couldn't read an LVM snapshot's metadata. I get the message to press "I" for interactive startup. UDEV loads and the system tries to mount all filesystems. Errors appear stating that it couldn't mount various LVM partitions. Startup fails due to the mount failure, the system reboots, and the steps repeat.

Troubleshooting done:...I have tried to run preupgrade again (the entry is still in my grub.conf file). The upgrade environment boots, but it fails to find the LVM devices and gives me a question to name my machine just like for a fresh install. I also tried booting from the full install DVD, but I get the same effect. Suspecting that the XFS drivers weren't being included, I have run dracut to create a new initramfs, making sure the XFS module was included. I have loaded the preupgrade environment and stopped at the initial GUI splash screen to get to a shell prompt. From there I can successfully assemble the raid arrays, activate the volume group, and mount all volumes -- all my data is still intact (yay!). I've run lvdisplay to check the LVM volumes, and most (all?) appear to have different UUIDs than what was in /etc/fstab before the upgrade -- not sure if preupgrade or a new LVM package somehow changed the UUIDs. I have modified my root partition's /etc/fstab to try calling the LVM volumes by name instead of UUID, but the problem persists (I also make sure to update the initramfs as well). From the device-mapper and I/O errors above, I suspect that either RAID or LVM aren't starting up properly, especially since prior OS upgrades had problems recognizing RAID/LVM combinations (it happened so regularly that I wrote a script so I could do a mkinitrd with the proper options running under SystemRescueCD with each upgrade).

I have tried booting with combinations of the rootfstype, rdinfo, rdshell, and rdinitdebug parameters, but the error happens so early in the startup process that the messages quickly scroll by and I just end up rebooting.

System details:4 1-TB drives set up in two RAID 1 pairs. FAT32 /boot partition RAIDed on the first drive pair. Two LVM partitions -- one RAIDed on the second drive pair and one on the remainder of the first drive pair. Root and other filesystems are in LVM; most (including /) are formatted in XFS.

I've made some progress in diagnosing the issue. The failure is happening because the third RAID array (md2) isn't being assembled at startup. That array contains the second physical volume in the LVM volume group, so if it doesn't start then several mount points can't be found.

The RAID array is listed in my /etc/mdadm.conf file and identified by its UUID but the Fedora 12 installer won't detect it by default. Booting the DVD in rescue mode does allow the filesystems to be detected and mounted, but the RAID device is set to be /dev/md127 instead of /dev/md2.

The arrays are on an MSI P35 motherboard (Intel ICH9R SATA chipset) but I'm using LInux software RAID. The motherboard is configured for AHCI only. This all worked correctly in Fedora 10.

Ubuntu Installation :: Upgrade To 9.10 Failed; Can't Boot And Have Encrypted RAID Disk?

Feb 23, 2010

I was running Ubuntu 9.04 Desktop on a headless Pentium 4 machine which is our file, mail, web & fax server. The two x 250GB SATA hard disks were in a RAID 1 array with full disk encryption. Ran the 9.10 upgrade via WEBMIN and it failed. I should have known then to copy over everything to a backup disk, but instead I rebooted.

On restart the machine accepted my encryption passphrase but promptly hung with a mountall symbol lookup error - code 127. So I can't start the machine to get at the disks, and using a Live CD is useless as it has no way to open the RAID array to get at the encrypted partitions. Although we have data backed up (as at last night) I'd hoped not to have to rebuild the entire server from scratch. But its looking bad.I have taken one drive out and plugged it into another machine (Hercules), and the partitions show up as /dev/sdb1 /dev/sdb2 /dev/sdb3.

If it weren't for RAID, I could open /dev/sdb2 the main partition) in Disk Utility and enter my encryption passphrase to get access. But RAID adds a layer of obstruction that I have not yet overcome. I used mdadm to scan the above partitions and created the /etc/mdadm.conf file, which I edited to show the 2nd drive as missing (rather than risk corrupting both drives). I activated the RAID array with mdadm, and cat shows:

Code:
root@HERCULES# cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sdb3[0]
1815232 blocks [2/1] [U_]

[Code]...

I've been searching the web for hours but have yet to find someone with a solution to this situation. If anyone has a thought on how to access this disk I'd be pleased to hear from you. In the meantime I will start building a new (9.10) machine from scratch, without RAID, 'cos that's probably going to be necessary.

Ubuntu Installation :: Dual Boot - Win 7 And 10.10 On Raid 0 - No Raid Detect

Nov 26, 2010

I have installed Ubuntu on my m1530 since 8.04 and currently dual boot Win7 and 10.10. I would like to dual boot on my PC, but I have run into a problem. I am not a pro at Ubuntu, but this problem I can not solve by reading forums like I have in the past.

I realize this is a common problem, but I have noticed people having success.

I have a M4A87TD EVO MB with two Seagate drives in Raid 0. (The raid controller is a SB850 on that MB) I use the raid utility to create the raid drive that Windows7x64 uses. I have 2 partitions and 1 unused space. Partition 1 is Windows, partition 2 is for media, and the remaining unused space is for Ubuntu.

I am running ubuntu-10.10-desktop-amd64 off a Cruzer 16GB flash drive that was installed via Universal-USB-Installer-1.8.1.4.

My problem like so many others is that when I load into Ubuntu, gparted detects two separate hard drives instead of the raid. I read that this is because kpartx is not installed on 10.10. I then went in LiveCD mode and downloaded kpartx from Synaptic Manager. Gparted still reported two drives. I opened terminal and run a few commands with kpartx. I received an error. (Forgive me I didn't write it down, but I believe it said something about a communication error. I will try again later and see.)

Currently I am reflashing the Cruzer with a persistence of 4GB. I am not familiar with this process, but I understand that my LiveCD boot will save information I download to it. I decided to try this method because I was going to install kpartx and reboot to see if this made a difference.

I am looking for any suggestions on a different method or perhaps someone to tell me that the raid controller or some hardware isn't supported. I did install ubuntu-10.10-alternate-amd64 on my flash drive, but fail to get past detecting my CD-ROM drive since it's not plugged in. If this method is viable, I will plug it in. I also watched the ..... video were a guy creates Raid 0 with the alternated CD, but it wasn't a dual boot and didn't use a raid controller from a MB.

Ubuntu Installation :: Dual Boot SSD Non Raid - 1 Terabyte Raid 1 Storage "No Block Device Found"?

Sep 15, 2010

It's been a real battle, but I am getting close.I won't go into all the details of the fight that I have had, but I've almost made it to the finish line. Here is the set up. ASUS Z8PE-D18 mother board 2 CPU, 8 Gig Ram. I recently added an OCZ Agility SSD, defined a raid 1 virtual disk on the 1 terabyte WD HDD drives, which will holds all of my user data, the SSD is for executables.The bios is set to AHCI. Windows 7 installed fine, recognizes the raid VD just fine.

I installed Ubuntu 10.04 by first booting into try and mode, then opening a terminal and issuing a "sudo dmraid -ay" command. Then performing the install. I told it to install the raid components, and told it to let me specify the partitions manually. When setting up the partitions, I told it to use the free space I set aside on the SSD from the Windows 7 install as ext4 and to mount root there. Ubuntu installed just fine, grub2 comes up just fine, and Windows 7 boots with out a hitch, recognizing the mirrored partition as I indicated previously. When I tell grub to boot linux however, it pauses and I get the "no block devices found" message. It will then boot, but it does not recognize the raid array. After Ubuntu starts up I can run "dmraid -ay" and it recognizes the raid array, but shows the two component disks of the raid array as well. It will not allow the component disks to be mounted, but they show up which is annoying. (I can live with that if I have to)

I have fixed a similar problem before by setting up a dmraid script in /etc/initramfs-tools/scripts/local-top ... following the instructions found at the bottom of this blog:[URL].. To recap: My problem is that after grub2 fires up Ubuntu 10.04.1 LTS (Lucid Lynx), it pauses, and I get "no block devices found" It then boots but does not recognize the raid array untill I manually run "dmraid -ay". I've hunted around for what to do but I have not found anything. It may be some timing issue or something, but I am so tired of beating my head against this wall.

Ubuntu Installation :: Raid Array Not Available After Upgrade?

Jul 11, 2010

After upgrading my ubuntu install my raid array is gone. The drives appear in blkid as "Linux raid member" and both have the same uuid. If I try to mount the drive via fstab I get a message that the drive is not ready or present. If I try to mount each of the two drives, one mounts successfully the other reports serious errors. Issuing a cat /proc/mdstat shows md_d0 as inactive.How can I re-establish my raid array? I have the data backed up so if I have to wipe out the disks to start over that's an option.

Ubuntu Installation :: Kernel Upgrade To 2.6.32-23-generic Broke My LVM - RAID And GRUB

Jul 4, 2010

I recently updated the kernel to the newest version(2.6.32-23-generic) using the update manager and now I am unable to boot in to my Lucid installation.

My setup is LVM on top of a RAID 0 array. My computer had been running in this configuration since Lucid was released.

The Error Code I get on Boot is to the effect of: /dev/mapper/ubuntu-os is not available.. and then I get kicked in to Busy Box.

Once in Busy Box if I try to use mdadm to mount the RAID array I get this error:

If I boot in to the live CD I can mount all of the partitions and LVM volumes, so it does not appear to be a failed drive or volume.

I have looked in the mdadm.conf, lvm config and grub config files and searched the "Google" for an answer with no-avail...

Ultimately I would like to find a solution which doesn't involve a re-installation.

Ubuntu Installation :: Upgrade From Another Distro To Server - Migrating Existing LVM - No Encryption And No Software Raid

Mar 28, 2010

I want to upgrade from another distro to ubuntu server for a few reasons. The only problem is I have a lot of data that needs to survive. here is how my computer is setup. I've 5 drives on the computer,

A- 10gb drive for OS and swap only, no data

B,C,D,E - 4x 500 GB drives in a LVM. they make up one large drive with xfs and this volume has about 1.2 TB of data. there is nothing fancy on it, no encryption and no software raid of course the little 10gb drive can be formatted no problem, but the LVM needs to be migrated over intact.

Ubuntu Installation :: 9.10 64, GRUB Can't Boot XP In RAID-1

Jan 12, 2010

I'm a long time windows user and it-tech but I have long felt that my geek-levels were too low so I installed Ubuntu last week (9.10 x64). Hopefully I can make it my primary OS. I have two 80GB drives in RAID-1 from my nforce raid controller, nforce 570 chipset. Then a 320 GB drive where I placed ubuntu and it's also where grub placed itself. And also a 1TB drive.

When grub tries to boot XP I get the error message: "error: invalid signature" I checked the forum as much as I could and tried a few things, but no change.

Drives sdc and sdd are the two drives in raid, they are matched exactly, but detected as different here. I really think they should be seen as one drive.

how I can make grub work as it should?

Also, if/when I need to make changes to grub, do I really have to use the live CD?

Code:
============================= Boot Info Summary: ==============================
=> Grub 1.97 is installed in the MBR of /dev/sda and looks on the same drive
in partition #1 for /boot/grub.
=> Windows is installed in the MBR of /dev/sdb
=> Windows is installed in the MBR of /dev/sdc

Ubuntu Installation :: RAID Array Will Not Boot (x64)?

Sep 15, 2010

I am using the 10.04.1 x64 Kubuntu live CD to install Kubuntu on my FakeRAID 0 array, I tell it not to install grub as i know it is still currently broken. the install goes flawlessly. However on first boot using my live grub CD unless i tell my computer to point to the CD it will hang (which it is told to boot from CD first so i'm not sure why it does.) When i tell it to boot to Linux, it will not boot saying the kernel is missing files (to much to sadly list, all i do not understand) then offers me a terminal to input "help" into for a list of Linux commands. Windows 7 pro x64 works just fine CD was downloaded VIA P2P if it matters

Ubuntu Installation :: 11.04 On Sata Raid Won't Boot?

Aug 20, 2011

I have a Asus P5Q-E with SATA Raid (fake Raid ?) with 2 250Gb disks on Raid 0 and have Windows 7 installed. Freed some space and want to install Ubuntu 11.04 alongside Win7. Install choosing the "alongside" option. Installed...reboot...grub rescue (error no such device). Win7 disk recovery and got access to Win7 again. Where is Ubuntu ? Nowhere... the free space continues free (not partitioned) and found no evidence of ubuntu install. Ok...second try with "something else" option, created /boot /swap and / partitions and installed grub on /boot partition (this time I want to use windows boot to choose...and if it fails the instalation again, at least I got Windows). Installed...reboot...grub rescue.

Again, the free space wasn't partitioned and the installer spend some time doing something but there is no evidence of ubuntu install. Also grub seems to be installed on first disk (even when I choose /boot as device bootloader installation) - I've used EasyBCD to create an entry on win bootloader and when I choose that got grub> (not grub rescue>).

Can Ubuntu be installed on such conditions ?

Ubuntu Installation :: Grub Multi Boot With Raid 0

Mar 20, 2011

There have been many postings on doing Raid 0 setups, and it seems the best way looks like softRaid, but there were some arguments for fakeRaid in dual boot situations. I've seen some posts on dual boot windows/linux in Raid 0, but I was hoping to do a multi-boot using a grub partition, with several Linux distros and Windows 7. There will also be a storage disk for data, but not in the array. From what I gather, I'll need a grub partition which can only reside on one of the two disks, one swap partition on each disk, then the rest I can stripe.

I've got two 73GB WD raptor drives to use for the OS's and programs. I'm just getting my feet wet with the terminal in linux (Ubuntu makes it way too easy to stay in GUI), and the inner workings of the OS, so I have several questions:

Is this going to be worth the effort? Obviously I'm trying to boost performance in boot and run times, but with Grub on a single drive, will I see much gain?

Does this sound like the right methodology (softRAID)? I only have two spare PCI slot's, which don't seem like they would be condusive to hardware raid, but someone who knows more could convince me otherwise.

Ubuntu Installation :: 10.04->11.04:often Get Degraded Raid Error At Boot?

Sep 1, 2011

I recently upgraded from 10.04 to 11.04 and I now often get boot messages about a degraded raid.

I'm fairly experienced, but I'm confused which raid it is talking about. I have a raid5 array, but I don't boot of that, and it seems fine when I finally get it to boot. Previously, I didn't have any other raid arrays[1], but now I seem to have two others called md126 and md127, they both seem to be degraded. Where did they come from?

[1] I *do* have two 80GB drives that I was booting from in RAID1, but that was a looong time ago, and I have since only booted from one of them. The partition table indeed shows partitions 1 and 5 are raid autodetect and /proc/mdstat shows they are degraded ([U_]). Could it be that this is causing the problem? If so, why has this only started to happen since the upgrade from 10.04 to 11.04?Anyway, perhaps it is a good idea to add in that second disk to the raid1 array. If so, how to do that? Note that, I've also noticed that when I boot and get to the screen when I select from the different kernel versions, I now get a couple of really old ones too - my thought is that these are from the raid1 disk that I stopped using. If I add it to the array, how can I be sure it will mirror in the correct direction?

It could be that I have fairly recently plugged in that second RAID1 disk, after a long time of not having enough spare sata sockets (I switched my RAID5 array from 8 disks to only 3 disks, so suddenly had a lot more spare sockets).

Ubuntu Installation :: Lucid Server - Won't Boot From Software RAID

May 6, 2010

I'm trying to install Lucid server (64 bit) and I'm having trouble getting it to boot from software RAID. The hardware is an old Gateway E-4610D (1.86GHz Core2 Duo, 2GB RAM, 2 500GB HDs).

If I install on a single HD, it works fine, but if I set up RAID1 as described here, the install completes fine, but on reboot this is what I get:

Code:
mount: mounting /dev/disk/by-uuid/***uuid snipped*** on /root failed: Invalid argument
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory

[Code].....

When I set up the RAID using the ubuntu installer, I created identical main and swap partitions on each of the two drives (all four are set as primary), made sure the bootable flag was on on the two main partitions, then created a RAID1 out of the two main partitions, and another RAID1 out of the two swap partitions.

Ubuntu Installation :: Boot Disk Image For Install On AMD RAID PC?

Sep 3, 2010

I tried installing Ubuntu 10.04 WS on my PC but it did not see any disks to install on. I believe this is because my drives are all configured as RAID. My mobo is an Asus M3A78-EMH HDMI AM2+ socket with an Athlon 2X 5000+ CPU. The chipset is AMD 780G. I have the BIOS configured for RAID drives and I already run Win XP x32 and Win 7 x64 on it. My boot drive is configured as 'RAID READY' and I have 2 RAID 1 disks consisting of pairs of SATA drives.

From what I have researched it seems that with some tuning it should be possible to install Ubuntu 10.04 but I have little Linux experience and don't want to mess up my existing drives. I have installed Linux before a few times and run it but never with RAID. Is anyone aware of an existing disk image that I will be able to install from on my system or would it be possible for someone to create one for me to use?

Ubuntu Installation :: Dual Boot 10.10 With WinXP - RAID Got Corrupted

Oct 21, 2010

I originally wanted to dual install 10.10 64 Ubuntu with Windows 7 64 RAID 1 HP PC, but RAID got corrupted and I could find no fix online except using fakeraid unsupported software. The whole thing blew my muind. I gave up after 4 or so reinstalls of windows 7 to fix RAID. So I decided to install a dual boot 10.10 Ubuntu i86 with my old WinXP i86. I kept getting these errors at boot up: unknown filesystem, file not found, out of disk, no such partion and so on. I tried just about every grub reinstall I could find, including article here: "Recovering Ubuntu after Installing Windows."

After a number of tries my friend installed Ubuntu successfully, but then when I installed windows xp I am stuck here, again. I did do the Reload grub tutorials again as well. I may just give up on WinXP and have my friend reinstall Ubuntu for me.

Ubuntu Installation :: Blank Screen On Boot - GRUB With RAID

Mar 19, 2011

I am trying to install Ubuntu Server 10.10 on a computer with 5x 1.5 TB HDDs. I went through the process of partitioning the five hard drives into three partitions each:

sd*0 is a 300MB partition for /boot, RAID1, 2 active, 3 spare
sd*1 is a 500MB partition for swap, RAID1, 2 active, 3 spare
sd*2 is a 1.5TB partition for /, RAID5+LVM, 5 active, 0 spare.
md0 is the raid1 on sd*0
md1 is the raid1 on sd*1
md2 is the raid2 on sd*2

During the install, everything seemed to work fine with the formatter, but the installation ended in error. I booted into rescue mode and found that though all the drives were U (in /proc/mdstat), it was resyncing. I let this run (overnight) and the next day, jumped back in and installed the OS successfully.

However, after installing GRUB, when the installation process asked me to reboot, the system came back up with a blank screen (blank, save for a blinking cursor) and didn't move from there. I am thinking that the problem is GRUB, since I can boot into the main LVM partition via the rescue option on the install cd. Here's what bugs me:

Ubuntu Installation :: Wish To Install As Dual Boot On A Nvidia RAID

Ubuntu Installation :: RAID 0 And Win7 Dual Boot - Grub Cannot Install

Sep 13, 2010

I'm having serious troubles to install ubuntu-10.04.1. My raid is an hardware raid with intel chipset. Note that win7 is already installed and working with my raid. I made some space from windows, to install Ubuntu (40gb). First, I run the installer, everything seems to be fine. I choose to install Ubuntu were there is the most space free (sorry, I'm not sure about the real terms used there).

Then my partition with the vista loader appears. So the installer can see my raid, and should work fine (everything is detected correctly). But once I'm in the end of the installation (around 95%), a pop-up appears, and tells me that Grub can't install in /dev/sda and it's a fatal error. I can choose an another destination, but it doesn't seems to work.

Ubuntu Installation :: 9.10 Wont Boot After Fresh Install - Raid Grub Missing ?

Mar 12, 2010

I had ubu 904 and vista installed on an 80gb drive, i had a spare 80gb drive also. I setup a raid0 config in my bios, then installed ubu9.10 onto it. All was fine until the very end, and then it said grub failed to install.

So i rebooted, and im left with a blinking cursor. How do i install grub? Ive installed ubu a few times now and never had an issue so now im lost.
