Upgrade to 3.14.0 messed up raid0 array (btrfs cleaner crashes in fs/btrfs/extent-tree.c:5748 and fs/btrfs/free-space-cache.c:1183 )
Soon after upgrading my server from 3.14rc5 to 3.14.0, my server went
into a crash loop.
Unfortunately because I used btrfs on my root filesystem, the problem
didn't get logged because btrfs failing on a separate array prevented
another thread to use btrfs to write on a healthy /var filesystem.
So I found my system in a reboot loop, and after commenting out the
devices in /etc/crypttab, prevented btrfs from mounting dm-5, which has
restored my system to sanity for now, but with a missing filesystem.
dm-5 was a 2 device raid0.
I'm afraid of mounting it, because I think it'll crash my system again,
but I'm happy to run commands against it.
Question #1:
Will mounting with read-only stop the cleaner process?
Question #2:
Is mounting with recovery,ro and copying the data out if I can the best
way to recover?
(and destroying, recreating the filesystem after that)
Question #3:
Any idea what happened and what bug I hit?
Thanks,
Marc
