Title:
Ubuntu Eoan 10.10 fails to boot after updating from 19.04 disco with
btrfs
Status in linux package in Ubuntu:
Confirmed
Bug description:
Current eoan v5.3.0 kernel has a much more strict tree checker for
btrfs and may fail to mount the file system in case there are bad
inode generations after an upgrade. This may be the case on file
systems created before 2014.
A a result of failing to mount the user will land in the initramfs
busybox. Manually trying to mount will display the failing inodes.
Unfortunately the built-in (in initramfs) btrfs checker from btrfs-
progs 5.2.1 can not repair this problem.
That is related to this patch for btrfs-progs 5.3-rc1:
https://lore.kernel.org/linux-
btrfs/[email protected]/T/#mfa319e441efe5a3b66955891ed61ed47e33bf543
As a work around after the upgrade the user should boot the old
(disco) kernel and should be made aware not to remove this. As a more
permanent resolution then linux-oem can be installed.
In principle a script can be devised to save the failing inodes with new, or
when available btrfs-progs could be updated to 5.3 to repair the file system.
In any case it should be considered that the failing inodes might be present on
multiple snapshots of the fs.
