First off, if this is covered in a FAQ somewhere that I haven't located,
please let me know.
What I have is 8 9GB scsi drives on 1 Adaptec 7890 controller. I'm
trying to set up a 7 disk raid5 device with 1 spare disk. However,
'mkraid /dev/md0' returns:
handling MD device /dev/md0

disk 0: /dev/sdb1, 8883913kB, raid superblock at 8883840kB

I found an earlier post in the archives that recommended removing all of
my partitions, rebooting, creating my partitions again and immediately
running mkraid --force /dev/md0 without a reboot, but this returns the
same error. /var/log/messages doesn't show me any errors either, so I'm
stuck. Any ideas?
Redhat 6.0/Kernel 2.2.10/mkraid 0.90.0
Oh, and no, this is not any part of my 'regular' filesystem, it's going
to be mounted under /www if I ever get it working ( have a couple
hundred sites that need to be served :P ).
Thanks,
