Is this solution supported by RedHat? If I am correct, it isn't: https://access.redhat.com/kb/docs/DOC-17651
With HA-LVM you will loose the live-migration... And if I am correct, as the redhat cluster suite's resource script do not activate the vgs (or lvs) exclusively (that can be an option when you are using clustered LVM), nothing would prevent the second node to start the vm that is already running on the master node (which would probably kill your filesystems in your vm) in a split brain situation (except a "reliable" fencing). If I am correct, the only supported method is CLVMD+GFS(2) if you want live migration for a VM. Is this true? Regards, Balazs Jeff Sturm schrieb: > GFS2 isn't the only way to get live Xen migration.
