This is my raidtab file:
raiddev /dev/md0
raid-level 0 # it's not obvious but this *must* be # right after raiddev
persistent-superblock 1 # set this to 1 if you want autostart, # BUT SETTING TO 1 WILL DESTROY PREVIOUS # CONTENTS if this is a RAID0 array created # by older raidtools (0.40-0.51) or mdtools!
chunk-size 32
nr-raid-disks 2 nr-spare-disks 0
device /dev/hda3 raid-disk 0
device /dev/hdc3 raid-disk 1
The partition table:
Disk /dev/hda: 16 heads, 63 sectors, 59556 cylinders Units = cylinders of 1008 * 512 bytes
Device Boot Start End Blocks Id System /dev/hda1 * 1 21 10552+ 83 Linux /dev/hda2 22 542 262584 82 Linux swap /dev/hda3 543 59556 29743056 fd Linux raid autodetect
My board is a Gigabyte 6BXDS BX-Chipset 2 Celerons@533 MHz
