Hi,
we have a raid5 with persistent superblock and need to replace one of the
harddisks.
Currently 3 of 4 md-devices (each built from 5 partition of 5 disks) work fine
and have full raid5 support, but for md0 only 4 partitions are active.
What happens if we shutdown the server and replace the faulty disk by a new
unpartitioned one ? I'm a bit worried that due to the autostart due to the
persistent superblock something could become destroyed.
Actually I would prever an kernel parameter to disable raid autostart and
first partition the harddisk, but so far I havn't found something like this.
Thanks,
Bernd

It should work fine.
