I can't tell you if it is the best solution or not, but I have the above working. I am running gfs2 ontop of lvm2-cluster on drbd in primary / primary mode, HA is done with cman and IPMI fencing. P.S. I am using 10 gig infiniband for DRBD to keep all that traffic off the ethernet interfaces. If you look on ebay you can buy it for next to nothing, I paid about $45 for the 10 gig cards, $35 for cables and $400 for a switch. ><> Nathan Stratton CTO, BlinkMind, Inc. nathan at robotics.net nathan at blinkmind.com http://www.robotics.net http://www.blinkmind.com
