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). [Screenshot from 2021-10-15 04-29-15.png]
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, this operation may lead to data corruption and should be used with care. Please contact support prior to running this command##########################################Are you sure you want to proceed? [y/n]yselect fn_db_unlock_disk('e0f46dc5-7f98-47cf-a586-4645177bd6a2');INSERT 0 1unlock disk e0f46dc5-7f98-47cf-a586-4645177bd6a2 completed successfully.
Any other ideas?

Hi David, Taken from [1], for setting the password for the engine user. su - postgres
psql
postgres=# create role engine with login encrypted password 'password';
You can set the password for the postgres with 'sudo passwd postgres'(Alghout the password should be postgres)
For unlocking the disk, follow the example here [2] $ PGPASSWORD=xxxxxx ./unlock_entity.sh -t disk -q

I am trying to put a host into maintenance mode, and keep getting this error:
Error while executing action: Cannot switch Host cha1-storage.my-domain.com to Maintenance mode. Image transfer is in progress for the following (3) disks:
e0f46dc5-7f98-47cf-a586-4645177bd6a2, 06bd3678-bfab-4793-a839-ec8cad4b96e5, 13cef086-3878-463b-a224-cc42b44d8468
Reviewing documentation online, it seems I need to do this: PGPASSWORD=pass /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t disk e0f46dc5-7f98-47cf-a586-4645177bd6a2 PGPASSWORD=pass /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t disk 06bd3678-bfab-4793-a839-ec8cad4b96e5 PGPASSWORD=pass /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t disk 13cef086-3878-463b-a224-cc42b44d8468 /usr/share/ovirt-engine/setup/dbutils/taskcleaner.sh -R
When I run those commands, it *seems* to run successfully. However, I don't think that I have the correct password, because I cannot get a psql interface:
[root@ovirt-engine1 ovirt-engine]# psql -U admin -h localhost -p 5432 psql: error: FATAL: Ident authentication failed for user "admin" [root@ovirt-engine1 ovirt-engine]# psql -U admin -W -h localhost -p 5432 Password: psql: error: FATAL: Ident authentication failed for user "admin" [root@ovirt-engine1 ovirt-engine]# psql -U engine -h localhost -p 5432 Password for user engine:
Checking https://www.ovirt.org/develop/developer-guide/db-issues/postgresql-changing-..., I tried: [root@ovirt-engine1 ovirt-engine]# read PASSWD /etc/pki/ovirt-engine/encryptpasswd.sh [root@ovirt-engine1 ovirt-engine]# cat /etc/pki/ovirt-engine/encryptpasswd.sh $PASSWD cat: /etc/pki/ovirt-engine/encryptpasswd.sh: No such file or directory cat: /etc/pki/ovirt-engine/encryptpasswd.sh: No such file or directory
I must be doing something wrong here.
1) How can I reset the Postgres password? What user should I be using? 2) Once I have the correct password, will the commands I provided earlier work to unlock the disk?
