Re: [Xen-users] small cluster storage configuration?

I just looked at GlusterFS and VastSky - these seems to be aimed at
aggregating storage located across different servers. Correct me if I'm
wrong, but this seems to me the opposite of what you are looking for:
you want HA, so data needs to be replicated to be available via
different servers, right?
I'm running IET. Next project I would try AoE though.
Running anything on top of that in the way of a cluster file system?
IET is running on DRBD - no cluster file system necessary. Pacemaker
sees to it that only one node is using the iSCSI connection actively for
a particular DomU. You could think about using a cluster file system to
offer the Xen config files to all nodes, but I simply fixed this by
syncing these files with csync.
