Neil,
thank you very much for your help ..
> mdadm -C /dev/md0 -l 5 -n 3 /dev/hda3 missing /dev/hdc3
Did that, once with 'missing' in each place. All I get:
cdimage root # mdadm --create /dev/md0 --raid-devices=3 --level=5
--spare-devices=0 --chunk=64 missing /dev/hdb3 /dev/hdc3
mdadm: /dev/hdb3 appears to be part of a raid array:
level=5 devices=3 ctime=Tue Jan 20 10:35:45 2004
mdadm: /dev/hdc3 appears to be part of a raid array:
level=5 devices=3 ctime=Tue Jan 20 10:09:43 2004
Continue creating array? y
mdadm: array /dev/md0 started.
cdimage root # mount -r -t reiserfs /dev/md0 /mnt/gentoo/raid/
mount: Not a directory
cdimage root # cat /proc/mdstat
