Re: [dm-devel] [BUG] pvmove corrupting XFS filesystems (was Re: [BUG] Internal error xfs_dir2_data_reada_verify)



(Quick pointers that might be relevant)

EAGAIN, I'm not aware of dm itself returning that on the i/o path.

For 3.8 issues, read dm-devel around https://www.redhat.com/archives/dm-devel/2013-February/msg00086.html
(I queued the dm-side fixes for linux-next earlier today)

For pvmove, check exactly which version and whether discards are enabled: there
was a userspace bug for a short period some time ago when discards were enabled.
