Enable RAID on the boot disk without a reinstall
Authored by: brainiacboy on Oct 19, '04 01:33:32AM

Wished I had known about these two alternatives, I have a mirrored drive setup on a G5 but I did it the hard way, repartition and reinstall. But, does Apple really only support mirroring (or striping) of entire drives? Serious server systems allow making RAID objects at the partition level which allows for a whole lot more flexibility. Is it possible to mirror say only the first partitions of two drives, leaving the other partitions as normal or for use as stripes or whatever?

They may allow for flexibility, but they are anything but serious. One thing RAID (Redundant Array of inexpensive Disks) level 1 (AKA mirroring) likes is to have the read/write heads move in sync between all drives. When you start doing RAIP (Redundant Array of Independent Partitions) you loose the ability to keep the heads in sync, and in turn hamper your performance. A lot.

Then there is "RAID" level 0... there is nothing redundant about striping, therefor it isn't RAID, it only uses multiple disks.

vacuums do not suck. they merely provide an absence that allows other objects to take the place of what becomes absent.
