Linux 3.14.1 is affected by serious Btrfs regression(s) that were fixed
in
later releases.
Unfortunately even latest Linux can crash and corrupt Btrfs file system
if
OSDs are using snapshots (which is the default). Due to kernel bugs
related to
Btrfs snapshots I also lost some OSDs until I found that snapshotting
can be
disabled with "filestore btrfs snap = false".
I am wondering if this can be the problem.
Very interesting... I think I was just hit with that over night. :)
Yes, I would definitely recommend turning off snapshots. I'm going to
do that myself now.
Have you tested the memory in your server lately? Memtest86+ on the
ram, and badblocks on the SSD swap partition?
