Description Vikhyat Umrao 2021-06-17 10:48:38 UTC 
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!
Comment 2 Vikhyat Umrao 2021-09-22 15:14:43 UTC 
Moving to 5.0.z2 because of this bug https://bugzilla.redhat.com/show_bug.cgi?id=2003776

Bug 2003776 is verified now in 5.0.z1 and `autotune` works perfectly fine in 5.0.z1.
Comment 6 Sebastian Wagner 2021-11-04 15:51:21 UTC 
Upstream probably does not want to enable this by default, as autotune expects to have the hardware exclusively used by Ceph, which is not a safe default for upstream.

There is no particular action required from OSP. See https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/features/cephadm.html#scenario-deploy-hyperconverged-ceph
