Hi folks,

I just had a disk failure of one of the members of my RAID-0 boot disk. Fortunately for me it turned out to be the non-boot disk (ie I had hda and hdc mirrored, and hdc was the one that died), however it does raise a question:

If the disk that failed turned out to be the boot disk, how would I boot off of the survivor? ie if hda had died, how do I boot of hdc once I'd replaced the dead one?

I suspect the answer is "get a rescue CD", but if there are better answers I'd like to hear them.

You say RAID-0, but your description implies RAID-1. Which is it? If you lost a drive in a RAID-0 set you have nothing. If you lost a drive in a RAID-1 set, just change the boot drive in your PC BIOS to point to the remaining member.

Yeah, it was a long week last week. It's a RAID-1 survivor. A RAID-0 survivor is only good for use as reformatable disk space.

Why don't I clean this up and repost it.
