Hello,

I've got RH9 servers running in a few locations, with some 'valuable' data
in a mirrored RAID partitions.

One such site recently had a disk crash in the mirror and we removed the
disk from the system. However, a replacement was not readily available and
the data was needed day-to-day. 

When we booted the machine it autodetected the single raiddisk, but the boot
stopped because the second disk was 'moved' (i.e. the system had several
other disks, which moved in system-ID because of the crashed disk's
removal).

All non-raid partitions could work with this just fine (because of the use of
labels, thereby abstracting the disks from their system-id's [sda, sdb,
etc]), but if the boot still hangs on the raid-detect, such 'fail-safe'
measures become a bit academical.

Is there another way (other than ensure there is only one raid-device and
it's physical disks are the last in the system-id's; something which is
unpractical when using three scsi-controllers and multiple disk-arrays) to
ensure a system comes back up alright, even with a malfunctioning array? 

I guess hoping the raidtab can use disklabels anytime soon would be asking
for too much... ;)

Kind regards,
- Joop Carels.
