with gluster with replication you don't care (well less) if a host fails?

Hi,
I think your problem is the following:
if you put your shared storage on
the same servers where the HA-VMs run
and you lose one of those servers, you
inherently also lose the disk space on
this server.
Gluster can, in theory, circumvent this.
But afaik (read on this very ml) it is
not
I currently have a new setup running ovirt 3.3.3. I have a Gluster storage
domain with roughly 2.5TB of usable space. Gluster is installed on the same
systems as the ovirt hosts. The host break down is as follows
Ovirt DC:
4 hosts in the cluster. Each host has 4 physical disks in a RAID 5.
There was another recent post about this but a sum up was:
You must have power fencing to support VM HA otherwise they'll be an issue
with the engine not knowing whether the VM is still running and not bring
it up on a new host to avoid data corruption. Also make sure you have your
quorum setup

I'm not sure what you mean by NFS each host, but you'll need some way to at
least ensure the data is available. Be that be replicated gluster or a
centralized SAN etc.
