As this relates to an old version of ubuntu, I have now posted the question to serverfault.

I work on a server where the operating system is installed on an SSD but data storage is on internal harddrives set up in a RAID system. Recently I have been unable to mount the raid system when booting, while the operating system loads fine. I suspect technicians hit the server while it was running, due to scratches on the case but I am not sure.

When I boot the computer I get the error message The drive for /home is not ready or present (the same message for /Data and /Backup. I entered the recovery shell and ran fsck -A as suggested in the post here, but I get the message that / was busy.

I then booted into recovery mode and ran fsck -A, but I get the message that

fsck.ext4: Unable to resolve 'UUID=334eef34-16c4-45ec-9cc9-5f40e9f8207d'
fsck.ext4: Unable to resolve 'UUID=19bf1002-fa4b-4462-9ea6-807d5b0f312b'
fsck.ext4: Unable to resolve 'UUID=0f556fa7-b061-4c22-b84b-97e2e3f1b545'

At ubuntuforums I found the suggestion to edit /etc/fstab but I am out of my depth here as I do not really understand what I am messing with.

running blkid returns

/dev/sda1: UUID="7c05724f-61bd-4d70-b908-f6c83c4365b8" TYPE="ext4"

and running cat /etc/fstab prints

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

I noticed that the missing UUIDs are the same as the ones in /etc/fstab/ but does not match the ones in blkid. Is there some way to figure out which UUIDs goes where and restore the file system?

The vast majority is backed up so the damage is not great, but there are a few things that would be nice to restore.

I work on a server with Ubuntu 14.04.5 LTS, if that makes a difference.

  • For whatever reason your workstation cannot contact the raid array on the server. Can you reboot the server? Can you ping the server to check its not a network problem? – PonJar Oct 02 '19 at 08:43
  • I have rebooted the server, the operating systems loads fine. I can also ssh into the server. All output I have shown is from the server. – Lars Oct 02 '19 at 08:48
  • Sadly v14.04 is EOL and so off topic here now. You might get more information about your issue from: https://meta.serverfault.com/questions/4111/what-is-a-professional-capacity – graham Oct 02 '19 at 09:34

    Fair enough, although I doubt this question is in any way related to the version of Ubuntu I am running. I will post the question on serverfault. – Lars Oct 02 '19 at 09:47
