If the inconsistency is due to the log having updates for an off-line volume, the filer
asks whether to discard them.

,QFRQVLVWHQF\'XHWR2WKHU5HDVRQV

If there are many inconsistencies that cannot be repaired, the filer discards the incon-
sistent contents and creates a core dump file. The file requests received during the
last few seconds before the filer shuts down are lost. This does not cause the file sys-
tem to become inconsistent, but files written during the last 10 seconds before
shutdown might contain old or incorrect data. Also, because the parity of some
recently written stripes might be incorrect, the filer must do a parity check on the
entire RAID array. The parity check, and any correction, is performed on-line; that is,
the filer conducts the test in the background while continuing otherwise normal
operation.
This kind of data error can happen only when you boot a system after a failure or after
you turn off a filer without using the halt command.

If mounts fail and clients see stale file handles, it might be because you renamed a
volume and it is not exported anymore. This is because the new volume name was
not in the /etc/exports file on the root volume.

To fix the problem, edit the /etc/exports file on the filer default volume to change the
old volume name to the new volume name.
Results: The problem is resolved.
