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,
