Hi!
I'm on duty today and were able to check osinfo following your advise. Not sure how
exactly we've managed to interfere with osinfo but reinstallation of
"redhat-release" package helped. Glad it was this easy to fix.
Do you know what might be the cause of the former problem? We probably won't be doing
any more cluster compatibility upgrades soon but it might be a sympthom of something else.
So I feel a bit uneasy about this.
Thank you!
