Hi Guys, (please excuse the noob if this is in the wrong place :rolleyes: )

Just watched Hak5 episode 1820, Great show (as always)... I have a quick question (or two or three).

I have a x16 Node Xen Cluster I am playing around with, I would like to use pooled storage to enable HA (high avialability). My setup has x2 SAS HDD on each node (non RAID), x1 for the Xen hypervisor (72GB) and x1 for storage (120GB) but without adding a SAN\NAS I can't figure out how I can setup HA, I would like to pool the second HDD but can't find a solution. I wondered if I could install a Linux based BLOCK level storage solution (like GlusterFS) on the Xen HDD and then add the second HDDs as storage bricks. Would this work and how would I do it or is there a better solution???

...Any suggestions greatly appreciated
