Setting up Software RAID

1. Make sure the kernel is compiled with RAID support:
   
   raidbox# cat /proc/mdstat
   Personalities :
2. Create partitions on disks to be combined in the RAID. Partition type should be "FD" (for RAID autodetect).
3. Create /etc/raidtab:
   
   raiddev /dev/md0
   

   raid-level linear
   nr-raid-disks 2
   chunk-size 32 # Not used for linear
   persistent-superblock 1
   device /dev/sda1
   raid-disk 0
   device /dev/sdb1
   raid-disk 1
4. Initialize RAID:
   
   raidbox# mkraid /dev/md0
5. Verify that the RAID is running:
   
   raidbox# cat /proc/mdstat
   Personalities : [linear]
   read_ahead 1024 sectors
   md0 : active linear sdb1[1] sda1[0]
