Hi guys

I have 3 node on proxmox 4.3. There are in cluster.
2 of them have glusterfs server 3.5 (official on proxmox).
Cluster works perfectly, glusterfs works good ,ha works fine and online migration works fine.
In HA i have one group and all vm's add to this group.
Everything works well except auto online migration.
When one node is fail, vm's on this server migrate on the next server and start this vm's. I wan't migrate online vm's when node break; (not start vm)
How to do it on proxmox 4.3 on glusterfs ? If you want more information please write on this topic.

On another cluster i have drdb8 with cluster and HA. Auto online migrate online works fine when one node fail. I want this solution on glusterfs and proxmox 4.3. This is possible to do it?

this is not possible (yet) with PVE/qemu. like I said, when the node dies, the RAM content is gone, so online migration is not possible. you would need some kind of hot-standby with mirrored RAM
