I just setup raid level 0 across 2 drives, disk 0 is a part of sda, sda3,
and disk 1 is the entire sdb, sdb1.
Everything went fine with setup, and creation of the raid partition, etc,
but after I did a reboot just to make sure things would mount properly,
etc, I had a problem.
Oct 17 18:02:53 www kernel: (read) sda3's sb offset: 1991936
Oct 17 18:02:53 www kernel: md: invalid raid superblock magic on sda3
Oct 17 18:02:53 www kernel: md: sda3 has invalid sb, marking faulty!
Oct 17 18:02:53 www kernel: can not autostart based on faulty sda3!
Oct 17 18:02:53 www kernel: export_rdev(sda3)
Oct 17 18:02:53 www kernel: autostart sda3 failed!
I did a mkraid --force-resync -f /dev/md0 and it's back to normal, but I
fear I will get the same error if I try again. Is there something I'm
not doing properly? I question the fact that sda3 is on a drive with
other non raid partitions, but this shouldn't be a problem, should it?
Thanks
