On the fleet's EL9 blk-mq kernels (AlmaLinux 9, kernel 5.14) the equivalent of noop is none. - add profiles::ceph::osd_scheduler, which renders a udev rule from the ceph_osd_devices fact pinning queue/scheduler to none on each OSD disk - reload udev and trigger the matched block devices so the change applies immediately, while the rule keeps it set across reboots and device re-add - no-op when the fact is absent/empty so VMs and non-OSD hosts are untouched - include the class from profiles::ceph::osd so it lands only on OSD hosts Claude-Session: https://claude.ai/code/session_01JUoARVdmhxKQHyyyp1pxeT	2026-08-02 21:40:27 +10:00
