| Funny you bring that up today; I spent the day working on that. I've implemented Gluster FS on my openstack running installation and written a script along that. Here is the implementation
node1- 1 instance running the node 1 crashes (could be anything atm) the script detect the node is gone (to be defined : heartbeat, monitoring, etc...) and relaunch the instance in the specified node.
I've tested it and successfully works. Just need to write the final touches Regards

I'd avoid depending on anything like that altogether. Try to design
your application so that it doesn't depend on any one instance being
up. It'll work out better in the long run.
