trying to repair a btrfs file system.

btrsfck --repair /dev/sda2

results in "out-of-memory" error

top seems to indicate that not more than 2gb-3gb was used.

It is a virtual machine, and so I added 30gb of RAM to it, and still "Out-of-memory".

enter image description here

dmesg

qgroup generation mismatch, marked as inconsistant.

Is there an alternate way of fixing this problem and/or how do I work around this one?

After disabling the quotas I get this the below. However, the disk check still wants to run, and after 11 hours did not complete.

  • How large is the drive, and is the VM 32- or 64-bit? The btrfs wiki's "Gotchas" section indicates that out-of-memory failures can occur if you have a large partition (>8TiB) and a 32-bit system. – ErikF Mar 15 '18 at 0:40
  • @ErikF It is 64 bit OS the drive is 20gb 30gb at the most I will have double check. – cybernard Mar 15 '18 at 1:05
  • Focusing on the qgroup generation mismatch, marked as inconsistant error message, are you using actually quotas? have you tried rescanning the qgroups with btrfs quota recan <path>? or disabling quotas entirely with btrfs quota disable <path>? BTW, see the "Stability Status" note in man btrfs-quota. See also btrfs.wiki.kernel.org/index.php/Quota_support. btrfs quota support is not what I would consider to be reliable enough to use. – cas Mar 15 '18 at 5:20
  • if you're not using quotas, then disable them. quota support in btrfs is not production-ready, stable code. it is known to have a performance impact. That stability status note in the man page I mentioned says STABILITY STATUS The qgroup implementation has turned out to be quite difficult as it affects the core of the filesystem operation. The users have hit various corner cases over time, eg. wrong accounting or system instability. The situation is gradually improving but currently (4.7) there are still issues found and fixed.. – cas Mar 15 '18 at 11:50
  • @cas Quotas may be enabled, but I am not using the functionality to limit anything.Had to boot from external media and the disable function says its not btrfs. Yet it is, and btrfs check does not give said errors. – cybernard Mar 15 '18 at 11:51

Something terrible happened

After doing a screen recording I noticed the boot volume had a different UUID for no good reason.

  1. boot from live CD
  2. edit search and replace /boot/grub2/grub.cfg

    old uuid -> new uuid

    System partially boots, but no kernel modules load....hmmm

After searching config files, I thought I would load the modules manually to see what the problem is.

Go to /lib/modules/4.15.8-1-default

!!SCREAM LOUDLY!!!

the subfolder kernel doesn't exist any more.

All the kernel modules were deleted!!!

Yikes!!!!

Back to a live DVD ISO

  1. mount the drive.
  2. active ssh service

Goto alternative computer

scp -rp /lib/modules/4.15.8-1-default/* root@1.1.1.1:/lib/modules/4.15.8-1-default

Reboot

The system boots normall????

Time to build a new VM a migrated the important files over.
