I believe the partitions are being set right. The first partition (Linux
native) is being used on each disk. The only other partition is a third
partition (whole disk) which is required by Sun (as I understand it).
If I don't create the RAID (with mkraid), then the disks each maintain
their partition tables on reboot. If I do make the RAID, then everything
appears fine, but on reboot the partitions are hosed.
Here is the raidtab file:
raiddev /dev/md0
raid-level 5
nr-raid-disks 7
nr-spare-disks 1
persistent-superblock 1
parity-algorithm left-symmetric
chunk-size 32
device /dev/sde1
raid-disk 0
device /dev/sdf1
raid-disk 1
device /dev/sdg1
raid-disk 2
device /dev/sdh1
raid-disk 3
device /dev/sdi1
raid-disk 4
device /dev/sdj1
raid-disk 5
device /dev/sdk1
raid-disk 6
device /dev/sdl1
spare-disk 0
