Description

Maybe we should play safe here and just remove that from ceph unit-file. The TasksMax is not even in fedora 23, so it is a really fresh feature. The ceph-common contains client packages, only (no daemons, no unit files). Also, we already have a downstream RHCEPH bz1335586 for the warning about TasksMax missing in RHEL. This was just a plain RFE for some future RHEL release (7.4 or 7.5, maybe?) to introduce these options for us -> moving back. Ok so lets postpone it for now. Let me rephrase my previous comment: We are quite happy the way it is, now. Let's use this bz as a remainder to inform us (RHCEPH) when (or if) there will be any behaviour change in this area in RHEL. Lukáš, it sounds like this will probably never be backported to RHEL 7? If we will backport this to rhel then with infinity as a default settings, so you should be fine in either case. Thanks Lukáš! Note that functionality realized by TasksMax is actually enabled by kernel's "pids" cgroup controller. This controller is not part of RHEL kernel because it was introduced quite recently. In order for us to backport this to systemd we first need pids controller backported to kernel. IIRC, patch introducing pids contoller wasn't very big so it should be easy to backport. pids cgroup controller is in kernel 3.10.0-372 or later. https://bugzilla.redhat.com/show_bug.cgi?id=1265339 I've already backported necessary patches.
