This is still an issue.
As part of my troubleshooting process, I manually migrated all of the VMs off of this
host. When I still couldn't put it into maintenance mode, I manually ran "yum
update" from the command line, and then rebooted it.
The oVirt UI detected that it was down, and marked it as "Unavailable" for a
while, but once the host came back up, everything was marked green again, and the host is
a useful part of the cluster.
Unfortunately, I still cannot put it into maintenance mode because oVirt still thinks
these disks are locked.

Thank you very much.
I was able to (re)set the `engine` user's password in Postgres.
Unfortunately, I'm still having trouble unlocking the disks.
The following command produces no output underneath "Locked
disks" when I run this command on the hosted engine VM:
[root@ovirt-engine1 dwhite]# PGPASSWORD=snip
/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t disk -qLocked disks
However, in the oVirt UI, when I try to put the host into maintenance
mode I continue to get the message that there are (3) locked disks (screenshot below).

I've tried the following multiple times:
PGPASSWORD=snip
/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t disk
e0f46dc5-7f98-47cf-a586-4645177bd6a2##########################################CAUTION,

Any other ideas?
