Don't use ata-raid yet in production server. I make some test, I try to
use ataraid mirror, compiled 2.4.13 (vanilla) kernel, copy kernel in
debian bootdisk, boot, mknod device nodes, make pertitions, install,
modify fstab, lilo. First thing where broblem comes is that lilo can't
handle ataraid device, no broblem make bootdisk, rdev correct root, boot
and up runnig. (there are also working lilo somewhere?)
But when power down one disk (simulate failure), machine die.
That and lilo broblem is good enough...
I switch software raid (btw. ata-raid is not hardware raid). Lilo work
great, you are able power down one disk, and machine still runnig,
hot-spare & hot-reconstruction working. It might be posible to hotswap
broken disk and reconstruct..?
btw promise don't boot if arrays are not defined. If you define array it
use two last sector. So don't use two last cylinder in partitions.
ps. last mail, msi-k7t broblem was kernel misconfiguration, I config
ata-disk module, but it can't be module with ata-raid.. (idea: ramdisk
root, ide module, hotswap disk, reload module...)
