A few people on the xen mailing have been talking about:
http://www.asplund.nu/xencluster/xen-cluster-howto.html
It talks about running DRBD on top of LVM. Is the above method faster
then running LVM on top of DRBD? The biggest downside of the above howto I
can see is that you must configure DRBD for every DomU. So what is best
out of the three?
Disk > Partition > DRBD > LVM > xen phy:{lvm lv}
Disk > Partition > LVM > DRBD > xen drbd:{drbd disk}
Of since I don't think you can resize if you put DRBD on LVM, just:
Disk > Partition > DRBD > xen drbd:{drbd disk}
I know they all must be faster then what I am doing now:
Disk > Partition > DRBD > LVM > gfs > xen tap:aio{file}
