Installation through DNF only include basics dependencies, you need to install RAID python lib on your system in order to make the Glances plugin works (see optional dependencies list here: https://github.com/nicolargo/glances#readme) .

My advice, if it is possible, uninstall Glances with DNF and use the following procedure to install Glances with all the deps you want: https://github.com/nicolargo/glances#pypi-the-standard-way, example:

pip install --user 'glances[web,smart,raid]'

or full faiture:

pip install --user 'glances[all]'

I had the RAID python lib installed. Anyways, thanks for the tip. Removed via DNF and installed it with pip. It works now, thanks!
