I'd personally first try to fix the engine<->vdsm comm issue.
I fully agree. I might then take exports of all VMs and do a fresh start
over. I'm not sure the upgrade instructions work, as the upgrade for 3.6->4.0 already activates much newer content. For example the quoted --upgrade-appliance options does not even exist, probably because a later package removed it. One would have to manually versionlock the 4.0 hypervisior packages.
How did you upgrade the host? yum update? Is is ovirt-node?
Currently the state is as follows: engine is running on the 3.6 branch,
all updates applied [1]. The hosting RHEL host is on the RHV4 branch with all updats in, but the gnutls mentioned [2].
I managed to flag the host as in maintenance mode, so I could ask it to
re-enroll the certs.
Did you? Please do.
I can see from the hosts logs, that the ssh connection works, and the certs have been updated. But now I see in the host's vdsm log that the SSL connection is being dropped.
This can also be because a 3.6 engine defaults xmlrpc and a new 4.3 host talks only jsonrpc. Not sure, perhaps you can change the host (on engine side) to use json rpc and it would work, although a 4.3 host is definitely not supposed to support a 3.6 engine. If all you want is to export the VMs, I'd downgrade the host to 3.6.
If you are ok debugging/fixing yourself and only need the occasional tip, fine. Otherwise, please provide more details - exact versions of engine/vdsm, last version that worked, whether you can reinstall the host or need anything on it, etc.
I'm infinitely grateful for any assistance! I didn't want to spam the
list with my first mail. I hope I provided some better information now. Thanks!
In the long run I will decommission this host. I need the VMs on it to
migrate to a fresh 4.3 3 host hyperconverged setup which is yet to be built. Actually I am abusing one of the three nodes at the moment as a backup system for this failed upgrade, so I'm blocked with going forward with that setup as well. ... :(
Another option you might attempt is to import the data domain directly from the new engine. Obviously, do this first on a test copy...
Re [2]: I'll use this opportunity to clarify something which is not obvious, since you use RHV and not oVirt.
There is a significant difference between oVirt and RHV regarding repos/channels. In oVirt, each minor version has its own repos, and users can choose freely which one they want. In RHV, this the same for the engine channels, but not for hosts. For hosts, there is only a single channel per each major version. So if you use RHV 4 host channel, you get latest. Older versions are still available there, but you have to play with yum to choose them, and in RHV this is considered not supported, other than using RHVH (RHV downstream of oVirt node) which can be used for specific cases (perhaps like yours, but not sure it would help).
Yes, for this specific case the best option is to use latest RHV-H from 4.2 time.
This has the advantage, for RHV customers, of not having to add a new repo to get updates, and the disadvantage of not being able to stay on a specific minor version when upgrading.
Good luck and best regards,
