raid 1

[Aaron Hatfield]

My raidtab looks like this:

raiddev /dev/md0
        raid-level      1
        nr-raid-disks   2
        nr-spare-disks  0
        chunk-size     4
        persistent-superblock 1
        device          /dev/hda7
        raid-disk       0
        device          /dev/hdd8
        raid-disk       1

This is only mirroring one partition
How can I mirror more than one partition?
