Software-RAID and partitioning

[Christian Pernegger <pernegger@chello.at>]

I have 3 18GB SCSI disks I want to use in a "new-style" Soft-RAID-5
configuration. At the moment I have

1. partition	sd.4	swap
2. partition	sd.3	ext2		(for squid)
3. partition	sd.1	raid-auto

This of course means I have to have the whole md device under one
mountpoint (the directories under which are the targets of symlinks under / .)

I'd rather be able to have a real seperate partition on the array for at least
/home.

Is it feasible to split the raid partitions (sd.1) on the disks and create an
md0 and an md1, or does this hamper performance?

Thanks

Christian
