Our assigned Red Hat engineer was on-site today and pointed out the blindingly obvious solution. Can't believe I didn't think of it: Run NFS as a clustered service and have the VMs mount that.

I should forfeit my RHCE. :-P On Mar 3, 2010, at 12:28 AM, Xavier Montagutelli wrote: > On Tuesday 02 March 2010 23:50:26 Jeff Karpinski wrote: >> I've got a 4 node cluster back-ended with iSCSI storage that's happily >> running 20 or so VMs. I now have a request to present some shared >> storage across several of the VMs and am wondering what's the best way >> to accomplish this.
