I'd ask in a KVM / or libvirt, ovirt type forum, but the answer would probably be to just use iSCSI targets for each VM image. That may be a good solution if you have a single storage server. But, it gets pretty clunky trying to to setup open-e for failover with 10-15 (or more as we grow) iscsi targets. That would be mean creating the source LV, target LV, with the same size and scsiID, replication task, etc, and adding them to the cluster for each VM.
Is that the way to go? Does my question make sense to anyone? I feel like I'm overlooking something more simple to manage.
Has anyone had luck with open-e active-passive (or active-active) and using gfs or glusterfs?
Thanks
