I'd like to second this question. The other day I tried a CentOS 4.2
install on two IDE drives. My goal was to mirror them (software raid
1) and put them in an LVM so that I might, in future, add two more
drives and add them to the existing mirror.
1) Is this possible?
2) If so, how? I could not figure it out despite trying what seemed
like every combination of options in disk druid.
I succeeded in getting a RAID 1, but not in putting a RAID inside a
logical volume.
Thanks,
Matt
