Hi,

We're trying to upgrade from 4.1.9 to 4.2.x and we're bumping into
an error we don't know how to solve. As per [1] we run the
'engine-setup' command and it fails with:

[ INFO  ] Rolling back to the previous PostgreSQL instance
(postgresql).
[ ERROR ] Failed to execute stage 'Misc configuration': Command
'/opt/rh/rh-postgresql95/root/usr/bin/postgresql-setup' failed to

As of the

/var/log/ovirt-engine/setup/ovirt-engine-setup-20180205133116-sm2xd1.log

file I could see this:

 * upgrading from 'postgresql.service' to
'rh-postgresql95-postgresql.se [2]rvice'
 * Upgrading database.
ERROR: pg_upgrade tool failed
ERROR: Upgrade failed.
 * See /var/lib/pgsql/upgrade_rh-postgresql95-postgresql.log for
details.

And this file contains this information:

  Your installation references loadable libraries that are missing
from the
  new installation.  You can add these libraries to the new
installation,
  or remove the functions using them from the old installation. 
A list of
  problem libraries is in the file:
  loadable_libraries.txt

  Failure, exiting

I'm attaching full logs FWIW. Also, I'd like to mention that we
created two custom triggers on the engine's 'users' table, but as I
understand from the error this is not the issue (We upgraded several
times within the same minor and we had no issues with that).

Could someone shed some light on this error and how to debug it?

Hi,
can you please attach also loadable_libraries.txt ?
 

Could not load library "$libdir/plpython2"
ERROR:  could not access file "$libdir/plpython2": No such file or directory

Well, definitely it has to do with the triggers... The trigger uses plpython2u to replicate some entries in a different database. Is there a way I can get rid of this error other than disabling plpython2 before upgrading and re-enabling it after the upgrade?

Thanks.

Thanks.
