Hi,
Yesterday, after update to 4.14.13 from 4.14.12 I got a corruptions of
btrfs. Each time transaction was aborted with error about something
being already present. Unfortunatly as logs were on btrfs partition as
well the only recovered part is:
Jan 11 20:52:30 babylon5 kernel: BTRFS: Transaction aborted (error -17)
Jan 11 20:52:30 babylon5 kernel: ------------[ cut here ]------------
Jan 11 20:52:30 babylon5 kernel: WARNING: CPU: 3 PID: 312 at
fs/btrfs/extent-tree.c:3089 btrfs_run_delayed_refs+0x249/0x260 [btrfs]
(after reboot)
Jan 11 21:01:02 babylon5 kernel: BTRFS warning (device dm-1): block
group 13971226624 has wrong amount of free space
Jan 11 21:01:02 babylon5 kernel: BTRFS warning (device dm-1): failed
to load free space cache for block group 13971226624, rebuilding it
now
First time it corrupted perf.js file in Firefox profile making seeming
zeroing it's entry (owner root:root, wrong file type, permissions
0000, timestamp on start of Unix epoch etc.). I could not find any
corruptions second time. After each time scrub finished without
problems.
