Hello,
I upgraded my cluster of 8 hosts with gluster storage and hosted-engine-ha. They were already Centos 7.3 and using Ovirt 4.0.6 and gluster 3.7.x packages from storage-sig testing.
I'm missing the storage listed under storage tab but this is already filed by a bug. Increasing Cluster and Storage Compability level and also "reset emulated machine" after having upgraded one host after another without the need to shutdown vm's works well. (VM's get sign that there will be changes after reboot).
Important: you also have to issue a yum update on the host for upgrading additional components like i.e. gluster to 3.8.x. I was frightened of this step but It worked well except a configuration issue I was responsible for in gluster.vol (I had "transport socket, rdma")
Bugs/Quirks so far:
1. After restarting a single VM that used RNG-Device I got an error (it was german) but like "RNG Device not supported by cluster". I hat to disable RNG Device save the settings. Again settings and enable RNG Device. Then machine boots up. I think there is a migration step missing from /dev/random to /dev/urandom for exisiting VM's.
Hi! Sorry about this trouble. Please file a bug about this, we will likely need some Vdsm + Engine fixes. Bests, -- Francesco Romani Red Hat Engineering Virtualization R & D IRC: fromani
