New LVM question
I was under the impression that RAID functionality was part of LVM and I should be able to setup mirrors to other disks using it.

But then various web reading leaves me to believe I might have to deal with the md driver at the same time.

I'm a bit confused.

Can someone point me to instructions on adding a mirror to an already created root partition, or tell me it can't be done so I can stop wasting my time.

New Lesson of the day
Don't:
#1 - Create an LVM root paritition on a single disk
#2 - Create a 3 disk md RAID5 set.
#3 - Add that set to the volume group.
#4 - attempt to remove the original disk holding the root partition, hoping for a clean migration.

Hard hang.
On reboot, drops be to busybox shell with LVM error messages.

Oh well.

New dont put root partition in any LVM
if the disk scheme fails so does root. If root fails you pop in a cd or netboot and restore.
thanx,
