But either the AFS fsck should check the logging data on the partition
or at least tell you logging is not supported on a vice partition. If
fsck can't support it the file server should not allow it to be used as
a vice partition either, as the last thing you want to have is a corrupted
partition full of data and no fsck that can recover.
