Can anyone answer my question?
I don't think LVM cares what kind of storage it uses, as long as it's a
block device.
So theoretically, you can mix local disc, FC storage, GNBD, and ATOE and
combine them using LVM. You might run into performance issues (GNBD are
slower than FC disks) and startup issues (LVM has to start after cluster
and gnbd-import successfuly start), but it should be possible.
The real question is WHY you want to do that.
AFAIK, if you combine 5 gnbd from 5 gnbd servers into one LVM, and you
are accessing a volume on that volume group, and one of the gnbd server
dies (or hangs), gnbd import will wait forever until that server is back
up. So you'll have five more single-point-of-failures.

Hi,
If I have 5 gnbd servers in the network, each one export 1 block
device, can I import all gnbd devices on each gfs client, and use lvm
to manage them as 1 shared pool, then mkfs_gfs on it?
Thanks,
Michael
