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:

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-db-pass.html, 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?
