Can anyone explain how affinity labels work in 4.4?
I created a label containing a host and a VM. I had assumed that would require
the VM to run on that host, but the VM continues to run on any host in the
cluster.
I then checked the 4.4 documentation and it says that I need the filters
What exactly are you trying to achieve? LVM is just an implementation detail of
oVirt so you shouldn't be interacting with on it on a normal basis.
If you want to share block devices between VMs then you can create a shareable
disk.

Depends what you mean by "sync" and "swap".
If you can keep the same NFS endpoint, but swap-in your upgraded storage under
the hood then I think you can do as you propose. Stop all VMs, put the storage
domain in maintenance, make you changes and bring the domain out of maintenance.
Sorry, I missed the fact that you also have HE in the same domain.
I think the previous statement still stands. But you'd be advised to stop the
ovirt-ha-agent and ovirt-ha-broker on all hosts as well.

You might find affinity labels are a better fit in this use case. It would
allow you to add/remove/move hosts in the future much more quickly than hard
coding affinity. But that still leaves the bulk configuration tasks.
The only way to do this quickly is with the REST API or one of the SDKs
The "long-winded" way is the only way I know of doing it.

You can definitely build a bare metal Engine and do a DB restore onto it. I've
done this before when I had problems. Obviously you will need a sane backup
from your hosted engine.
I'm surprised the NFS build didn't work though. You probably need to remove the
stale iSCSI hosted_storage
as allocated memory and it is a bug.
I am working on a fix right now.
