Isn't RAID supposed to be redundant disks, not redundant partitions? If that hda disk goes bad, the raid and redundancy is nowhere to be found along with your data. Right?
Software is more flexible than that. It works with partitions.
Of course, for redundancy purposes, you want to mirror partitions on separate physical drives. But you don't have to mirror all the partitions on all your drives.
For example, you don't raid swap partitions.
We do that. The thinking is that if a drive goes your swap is still accessible through the md device. Ultimately we are trying to avoid VM issues because we lost one drive.
