Re: [ovirt-users] 4.2 upgrade question

The CentOS 7 engine build pulls that in and uses it, for both client (always) and server (if configured to). This is the only combination that's tested and known to work. To use this on your remote PG machine, add there SCL repos and use them. You will need to upgrade your database to the new version, similarly to what engine-setup does if it's a local db. I do not think we have docs for this, see e.g. [2]. If you want to use some other (non-SCL) build of PG also on the client, I think it should not be too hard to make everything work, as this is what we do in the fedora build, but I didn't try this myself, nor know about anyone that did. It's probably enough to remove the file: /etc/ovirt-engine-setup.env.d/10-setup-scl-postgres-95.env If you go this way, note that you'll have to repeat removing it per each upgrade. Alternatively, you can add your own file there, with a later number, clearing the variables set in this file, e.g.: # cat << __EOF__ > /etc/ovirt-engine-setup.env.d/99-unset-postgresql.env unset RHPOSTGRESQL95BASE unset RHPOSTGRESQL95DATA unset sclenv unset POSTGRESQLENV __EOF__ And also install the postgresql client/libraries/etc matching what you have on your server.
