Hi all,
Ok, I need to get my head round RAID and LVM as I want to upgrade my
home server. At the moment, my disks are configured as per the top
part of this picture:-

I hope that makes sense. :-)
md0 is used for / and md1 for /home
As can be seen, if hdc dies, it should still work. If hda dies, it
will not boot.
What I want, from how I understand things, is represented by the
bottom part of that image. So all of hda and hdc become part of a
single RAID, and then LVM works on the resulting md0. Then I can
create partitions as required in the resulting vg. Does this sound
right?
I need to do this in a way that keeps my data. So I was going to
remove hdc from the original array, set that up as hda in the new
machine in a degraded array, with LVM etc. Once that is working, I was
going to then move the old hda to be the new hdc in the new machine,
boot with a rescue CD, and mount it as is so I can copy the data
across. Then I create the single partition, and add it to the array.
If I have gone way off track here, please let me know :-)
Thanks.
