SW/RAID with 2 SCSI-HDS

[scoozme]

Hi,

Before I go ahead and attempt to make an array out of my drives, does the default knoppix kernel support SW/RAID ? I have 3.1 installed on a box with 2 SCSI disks that are identical. One is unused so, now i want to try SW/RAID.

Look into " md " it's been quite a while since I played with it, so I can't help you any more than that. The md stuff is in raidtools (apt-get install raidtools)

Yes as a module, but if you wan't to boot from it, you'll have to compile it into the kernel


I find that mdadm is the best tool for administrating softwareraid - of which I know.

Well, you can create an initrd which loads the necessary MD RAID modules on startup. This is what I did in order to get a system up to the point where I could build a fresh kernel with MD support built in (after copying the relevant modules into the initrd's /modules/)...
