[ovirt-devel] engine-setup fail with: ValueError: invalid literal for int() with base 10: '8MB'

I tried to install engine from rpms on my development host. This host was running engine development setup (using make install-dev) for a couple of months. Building the rpms was successful, but engine-setup failed: 2021-06-03 23:37:41,370+0300 DEBUG otopi.context context._executeMethod:145 method exception Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/otopi/context.py", line 132, in _executeMethod method['method']() File "/usr/share/ovirt-engine/setup/bin/../plugins/ovirt-engine-setup/ovirt-engine/provisioning/postgres.py", line 192, in _ misc self._provisioning.provision() File "/usr/share/ovirt-engine/setup/ovirt_engine_setup/engine_common/postgres.py", line 541, in provision transaction=localtransaction, File "/usr/share/ovirt-engine/setup/ovirt_engine_setup/engine_common/postgres.py", line 276, in _updatePostgresConf needUpdate, content = dbovirtutils.getUpdatedPGConf(content) File "/usr/share/ovirt-engine/setup/ovirt_engine_setup/engine_common/database.py", line 1163, in getUpdatedPGConf expected=item['expected'] File "/usr/share/ovirt-engine/setup/bin/../plugins/ovirt-engine-setup/ovirt-engine/db/configuration.py", line 136, in <lambd a> int(current) >= int(expected) ValueError: invalid literal for int() with base 10: '8MB' 2021-06-03 23:37:41,372+0300 ERROR otopi.context context._executeMethod:154 Failed to execute stage 'Misc configuration': invalid literal for int() with base 10: '8MB' 8MB sounds familiar - this value was recommended in README.adoc: work_mem = 8MB So I configured postgresql.conf like this. I edited /var/lib/pgsql/data/postgresql.conf and change the value to: work_mem = 8388608 After that engine-setup succeeded. Looks like a bug, our verification does not support the valid configuration that we recommend. Nir
