raidhotadd and RAID1
Anyone familiar with software RAID?
I've inherited a system on which they want RAID1.
There are 2 identical IBM 18G SCSI drives, sda and sdb.
There was already a system installed on sda, so I followed
the instruction in the RAID howto on setting up a RAID with
this disk initially 'failed', copying the system to the initially
good disk in the RAID . This all went well and the system boots
from the RAID.
I wiped the original installation and partitioned/formatted this disk
just like the other one (same sizes and start/stop).
But when I try to raidhotadd it (after removing the 'failed' directive
from the raid config file) I get "disk to small". I tried to repartition
the drive so that the partition that's actually part of the RAID would
be bigger than the existing one but that made no difference...
Anyone with any ideas as to what might be going on?
