The question is:
Can you use LVM to do mirroring and striping at the same time, or do you
need to use
software raid1 below LVM for that?
I havent tried this recently.
When having multiple chassis, the risk is that a chassis goes down and
that part of a striped
LVM can affect the whole filesystem, going offline and if the drives
became corrupted for some
reason, it can have corrupted all of your data. If you used mirroring
between two physical volumes
on two enclosures and then stripe across those mirrors, you could
mitigate that.
I believe thats what I said. Make stripes across RAID1 mirrors. AKA
RAID10. My apologies if I was unclear.
