Hi, Procedure to change storage domain for Hosted Engine is here: https://access.redhat.com/solutions/6529691 (you can apply for free-of-charge RedHat developer license in order to get access to RedHat KB). You might consider trying it first on test cluster before doing that in production. But I would discourage you from using GlusterFS. Not sure if that is matter, but I saw that GlusterFS has quite serious issues with robustness against failures (it is likely that you won't lose data, but you might need more manual interventions to fix GlusterFS cluster than necessary) Maybe you could consider having redundant (active/passive) NFS server? And a comment about version of ovirt: there is no ovirt 4.6 as of now (actually, it is a question whether ovirt 4.6 will be ever released) Latest version of ovirt is 4.5 and it seems that latest version of Oracle Virtual manager is pretty much ovirt 4.4.

I successfully installed Oracle Linux Virtual Manager that's basically Ovirt 4.6. I have a datacenter, 2 separate cluster, 3 host per cluster (self hosted engine configuration). During the installation process I defined the nfs storage for the hosted engine VM, and now I'm in trouble. I can shut down any host but the one that serve the nfs. I understand lately that I need a distributed storage to obtain HA, then I added the glusterfs support. I can see my gluster volume but I can't add it as storage domain. It's simply doesn't appear in dropdown menu when I try to add it as new storage domain. A part for that: there's a way to move data from hosted_storage domain (the nfs one) to another one? I try to setup another one as main but no joy. If a try to move the disk from there it's say to me I can't. I searched on the web but I found several answers, starting from: "no you can't" to "with engine-backup utility" and I'm quite confused. Reinstall it isn't an option, i have approx 60 vm active. Any help it's appreciated. (forgive eventually mistakes, I'm not a native).
