Hi Casey, Thank you for your answer.>if you aren't ready for an OS upgrade, using Ceph in containers may help in the meantime
Then maybe you can put my mind to ease since we are running our cluster containerised since the Pacific release on the advised platform at the time, RHEL 8 (well OK, Alma 8).
We have since, as per recommendation, upgraded to Reef.However, as I understand the issue as outlined in the release notes and the call, the problem is that the new containers are performing a syscall that is not properly supported by the kernel of our host systems.
If that would be the case and had I not read the release notes, I can only hope that our testing procedure would have caught this issue before going into production. Would the issue be of the kind that produces subtle misbehaviour, there would therefore be a decent chance that this would affect our production environment.
Again, this is a minor release. Is it strange to expect minor upgrades not to brake compatibility with the kernel/cgroup versions that were current when going into production?
(If yes, I would like to call "foul" and ask for a VAR-decision (apologies for the football reference) :-) ).
With kind regards, Jeroen -- _________________________________________________ Jeroen Roodhart University of Amsterdam Strategic IT Consultant Science faculty j.r.roodhart@xxxxxx Researcher's IT support Tel. +31 20 525 7203 feiog-tech-science@xxxxxx -- See http://www.uva.nl/profile/j.r.roodhart for openPGP public key
