for some time now our storage machine using XFS stops the file
system due to some reason I don't seem to have found so far. In this
process the file system gets corrupted and the attached trace log is
shown. After xfs_repair is run it's running again for an always
changing amount of time. In general it fails within a few hours or
days. There are no relevant log messages before the entries shown
below and no immediate actions that lead to this condition. So far
my experiments (Ubuntu upgrade from 10.04 to 14.04, different kernel
versions, changes to the hypervisor) didn't show any lasting effects
(positive or negative). If any one could shed some light on what XFS
is trying to tell me it would be highly appreciated.

I've found the mention of 'xfs_dir3_data_reada_verify' in the
mailing list but didn't find a solution that was applicable.

Thanks in advance
