This bug was initially created as a copy of Bug #1973155 I am copying this bug because: Description of problem: Enable autotune for osd_memory_target cephadm brings the support for osd_memory_target with the help of this bug - https://bugzilla.redhat.com/show_bug.cgi?id=1939354 but in RHCS5 we have the autotune feature disabled. This bug will bring the support for autotune of osd_memory_target! Solution: We need to copy the documentation from https://docs.ceph.com/en/latest/cephadm/install/#enabling-osd-memory-autotuning to downstream
