I'm in the process of upgrading another production system from old tools
to new and noticed that you can't do a "raidstop" unless there is a valid
raidtab. It seems to me that with a persistent superblock, this should
not be necessary. The same applies to raidstart. Unless there is some
reason to change the raid configuration -- i.e. remove or deactivate a
piece, the superblock should provide all the necessary information. For
raid to go mainstream, these minor things should be cleaned up. The docs
seem to indicate that once the mkraid is done, the raidtab is really not
needed. That is not true in the case with raidstop, raidstart, initrd
starts and raid over raid (10, 51, etc...). All the info is there, the
raidtab is redundant and will cause errors if not up todate or is missing.
