Missing gems after OpenNebula upgrade from 5.10.5 to 6.6.0

Community Support Upgrade

Hello all!

I’ve just upgraded OpenNebula from 5.10.5 CE (CentOS 7.9.2009) to 6.6.0 CE (AlmaLinux 9.2). Everything went smoothly apart from issue related with the messages below in oned.log as well as during each one* command execution as oneadmin:

I’ve tried to install missing rubygem-* from OS repositories as below:

dnf install rubygem-ffi rubygem-curb rubygem-nokogiri rubygem-sqlite3 rubygem-mysql2

and restart OpenNebula services by

systemctl restart opennebula.service

but error messages still persist.

I have the following ruby* packages installed:

rpm -qa|grep -i ruby

I have a symlink in /usr/share/one/gems:

drwxr-xr-x 9 root root 4096 Aug 8 16:18 /usr/share/one/gems-dist

Not sure if one needs to execute

gem pristine --all

as it’s suggested on some forums.

@dclavijo , thank you for prompt reply!

I saw that document before. As far as I understand if after OpenNebula upgrade I would like to use packaged version of ruby gems (i.e. what comes with opennebula-rubygems rpm) I need to have /usr/share/one/gems symlink (and I do). But there is an error appear as I wrote in my initial post in that thread. So the question is how should I properly migrate from system-wide installed ruby gems (i.e. via script install_gems) to packages ones if it’s possible at all.

running install_gems takes care of installing the gems and the build dependencies the require for their extensions to be built. The gem pristine command will rebuild the gem extensions that need compiling.

This being said, you are better off with opennebula-rubygems package as the exact gem versions required by OpenNebula are already provided. This will prevent gem not found problems, extensions not built, version not packaged by the distributions, etc.

For that thread completeness. The solution was to define GEM_HOME and GEM_PATH environment variables defined as /usr/share/one/gems (can be put in the ~oneadmin/.bashrc file).

export GEM_HOME=/usr/share/one/gems
export GEM_PATH=/usr/share/one/gems
