You shouldn't mix raidtab and mdadm raidtab is obsolete with newer md. Uninstall it. using mdadm the above would be: mdadm --create /dev/md0 --chunk=32 --level=raid0 --raid-devices=2 /dev/hda1 /dev/hdc1 I suggest reading man mdadm (and why are you setting chunk to 32?) If you decide to go raid5 then you *must* use mdadm -F (otherwise you may well miss a disk failure - it's easy to do). Of course if you use raid0 this isn't important since you'll spot a drive failure as soon as the system crashes ;) David _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
