So that sounds like the host isn't able to communicate properly with the HEVM.  The cluster is still in global maintenance, but the HEVM still thinks that it isn't because the database says it isn't in global maintenance.

Yup, ovirttest1 ran out of disk space on Friday, we recovered it and everything seemed completely normal.

the postgres service is down on the HEVM, but that is because it's on our postgresql cluster, has been for weeks.  I can connect to it's database from within the HEVM using the credentials stored at /etc/ovirt-engine/engine.conf.d/10-setup-database.conf  I can tail the logs on the postgres master and ovirt can and does connect to it.

However, trying from ovirttest1 I cannot connect to the engine database using those same credentails, should I be able to?  It'd make sense to be able to connect to it....

It could depend on how you configured your pg_hba.conf for your DBMS instance.

Only the engine and dwh have to connect to the engine VM, a direct DB connection from the hosts is not required.

Looking at our logs, it appears that on Friday one of your hosts ran out of
disk space in its logs or temp directory. At which point connectivity started
to be spotty. I see a bunch of attempts to migrate VMs away from that host
(ovirttest1). All of them fail. That repeats a ton of times, I forwarded to
Saturday where it appears you had a bunch of stale locks which also repeates a
bunch of time until the engine VM gets restarted.

Then I see nothing but restarts of the engine and no apparent errors in the
engine log.

The server log does however reveal this:

Is your postgresql service running? That is the most likely source of the
engine not coming up.
