Hi of-team,
I've found some problems when creating raid1 devices.
1) the second raid1 device can't be created because no device exists.
2) If we add HD's which used to part of an old raid, it is not possible to
create a raid1 device with them.
mdadm: /dev/sda1 appears to be part of a raid array:
level=raid1 devices=2 ctime=Tue Nov 7 12:13:19 2006
mdadm: /dev/sdb1 appears to be part of a raid array:
level=raid1 devices=2 ctime=Tue Nov 7 12:13:19 2006
Continue creating array? mdadm: create aborted.
/dev/md0: Size must exceed minimum of 1024 sectors.
Failed to setup physical volume "/dev/md0"
sh: 1: Permission denied
I've written down a patch.

Sweet. Many thanks. Applied.
