Thanks a lot for the information. Btw, I can mount mit GlusterFS 3.4.2 NFS share now without specifying -o mountproto=tcp. Is upd now possible or is the protocol determined automatically now? I didn't test if hosted-engine-setup is able to mount GlusterFS NFS shares now without hacks, too - only discovered this new behavior on my hosts.

Slightly off-topic question: The storage options are stored in /etc/ovirt-hosted-engine/hosted-engine.conf, right? If I want to change the ip address of my storage I simply put engine into global maintenance mode, change IP in hosted-engine.conf and re-enable hsoted-engine vm again? Or are there more steps required?
