Title:
XFS Oopsing 4.2.0-35-generic Kernel - Block out of range
Status in linux package in Ubuntu:
Confirmed
Bug description:
After updating the Kernel on two of our Trusty Ceph servers from
3.19.0-33-generic (vivid) to 4.2.0-35-generic (wily), both servers
have now Oopsed multiple times accessing some of their XFS
filesystems.
Once this error occurs, the XFS filesystem becomes permanently
inaccessible. Even after a reboot, any attempt to access the
filesystem in question either by mounting it, or attempting an
xfs_repair will trigger the same Oops again.
These filesystems did not immediately fail until several hours after
the upgrade. I suspect that this is related to some housekeeping being
triggered within the filesystem.
This is the call trace from the moment a filesystem first failed:

I notice that xfs_da_grow_inode. Am I right in thinking that this was
a new feature add in the 4.2 kernel?
I expect that the history of these filesystems is important. These
would more have been formatted on a 3.16 kernel. Although I can't
inspect these failed filesystems, I can give information about the
other filesystems on the same servers, which I an 99% sure are
identical:

root@ceph-store5:~#
Thanks to the magic of Ceph, I've so far managed to avoid data-loss
and serious downtime, but I suspect there's a timebomb here waiting
for anyone who upgrades from an older kernel to 4.2.0+.
Please let me know is there's any further information I might be able to provide to track this down.
