Really? You mean, in your raidtab file, you can have a "raid-level" set to 1 with a "nr-raid-disks" greater than 2? That's neat. Or do you just mean mirroring two already-mirrored "md" devices (which occured to me after I sent my original message)? > I know the kernel also needs "autodetection" enabled, however I can't > seem to find that option in the kernel config.

Looking at the 2.4.18-3 sources that shipped on my RHL 7.3 box, it appears that RAID autodetect is always on, unless explicitly turned off (with the "raid=noautodetect" kernel option). Check out the drivers/md/md.c file, and search for the string "autodet". -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do not | | necessarily represent the views or policy of any other person, entity or | | organization.
