This happens when things go really really bad:
Jan 10 15:19:38 localhost kernel: Starting XFS recovery on filesystem: cciss/c0d0p1 (logdev: internal)
Jan 10 15:19:38 localhost kernel: Ending XFS recovery on filesystem: cciss/c0d0p1 (logdev: internal)
Jan 10 15:19:38 localhost kernel: Filesystem "cciss/c0d0p1": Disabling barriers, not supported by the underlying device
Remedy ? … Will see. Will edit the post later after i'll fix it ( if it's possible )
Later edit: Things went very bad. The whole filesystem was a mess. So the hammer solution was used. cfdisk / mkfs / restore the data.
