Hi everyone,
I am attempting to reinstall as a clean system, and the install is failing
silently.
At the point where I should be able to run engine-setup, the engine setup
utility is absent.
Installation medium: iso downloaded from
https://resources.ovirt.org/pub/ovirt-4.4/iso/ovirt-node-ng-installer/4.4...
As I attempt to install the missing dependencies, I keep getting deeper
into missing rpm land.
If this iso is no longer any good, even though it is only 4 months old, it
should probably be documented as bad or art least superceded by a fixed iso.
2:55 p.m.
Installing on a pristine Centos 8, I had to manually install the correct
version of ansible and postgres 12, then change the service name from
postgresql-12 to postgresql.
There are scripts looking for init.d/postgresql. Since Centos 8 implements
SystemCtl , there should be no init.d's (and there are none)

Progress ... there's something weird going on with the centos postgres
package(s). After a bunch of removes and installs of postgres the engine
install succeeded and the engine configuration succeeded.
Now it looks like not all of the postgresql libraries were loaded.

Update:
I scanned the centos libraries, and the lowest version of postgres that had
consistent package versions was 13. There was no libpq at the version 12
level in the centos RPM library.
I performed the manual installation process for the postgresql database at
the *Initializing the PostgreSQL Database* at
https://www.ovirt.org/documentation/installing_ovirt_as_a_standalone_mana...
, using version 13 instead of version 12.

New subject: Install Ovirt 4.4.10 to standalone system from iso fails
This came in just as the engine came up.
The final pieces of the puzzle were:
The database@server notation expressed in the logs is cool, but is not how
it is expressed to actually connect. That threw up a red herring.
I had to create all of the postgres users
Postgres ident authentication requires an ident server such as oidentd. It
used to be installed by default, but must be installed after the fact by
the system admin now.
Your guess about a not-clean system is not too far off. Just before this
email came in I hit a snag with the CA and key generation. I ran
engine-cleanup, then ran engine-setup again, and now the non-UI functions
of the engine are (apparently) back up.
Now the engine is running, but the web gui is throwing 500 errors. Internet
cut out so I'll get back to it in the morning.

It looks like a permanent fix was put in place in 4.5.
Should I consider just bumping up to 4.5 instead of trying to reinstall
4.4? Will I be able to recover my cluster from the engine backup?

Looks like this is not a clean system. You should disable any 3rd party
repos including EPEL and run 'dnf distro-sync --nobest' before intsalling.
They are likely the source of all of your dependency and missing package
issues. oVirt has a lot of dependencies from a lot of repos, and 3rd
party repos can mess up their delicate balance.

Not sure about recovering your cluster on a 4.5 install with a 4.4 backup.
I would also like to know if that is possible.
As a separate note, if you really need to install 4.4 instead of 4.5; I
managed to install a 4.4.10 hosted engine recently by
- extracting the ova from the ovirt-appliance rpm
- mount the image with guestmount
- do : echo "exclude=postgresql-jdbc" >> /etc/dnf/dnf.conf in the image
- rebuild the ova and point the installer to it when asked for a custom ova
path
This stopped the installation playbook from upgrading to the unsupported
postgresql-jdbc

New subject: Install Ovirt 4.4.10 to standalone system from iso fails
The last thing I need is the complication of having the engine hosted on
the cluster. It's way too easy to shoot yourself in the foot that way.

It's definitely possible. I had an issue with my 4.4->4.5 upgrade (always
make a backup first) and wanted to switch my engine from CentOS Stream to
Rocky anyway, so I built a new host and installed 4.5 using my backup from
4.4.10.
With 4.3->4.4 this was the only way to upgrade due to the OS version
change. 4.3 requires el7, 4.4 requires el8, and there is no in-place
el7->el8 upgrade (except maybe for very specific versions of RHEL). So
you had to make a backup on 4.3, reinstall your engine host with el8, then
restore the backup on 4.4. Plus a few extra steps if using
the self-hosted engine...
