Dear Users,
I have to upgrade our hyperconverged ovirt system from 4.3 to 4.4, but meanwhile I would like to change the storage backend under the engine. At this moment it is a gluster based clustered fs, but I don't really like it.... I would like to change to a hardver based iscsi storage. I just wondering, when I do the engine reinstall, I will install it to an other storage. Is it possible somehow?
The "canonical" way is: 1. On current engine machine: engine-backup --file=f1 2. (Re)Install a new host (with 4.4?), copy there f1, and: hosted-engine --deploy --restore-from-file=f1 This only handles your engine VM, not others. The new engine (with its hosted_storage on the new iscsi storage) will need access to the existing gluster storage holding the other VMs, if you plan to somehow import/migrate/whatever them. If unsure how to continue, perhaps clarify your plan with more details. Good luck, -- Didi
