Description Sam Wachira 2022-05-13 12:04:31 UTC

Describe the issue:
- Red Hat Ceph Storage 5 documentation does not appear to contain a procedure for configuring autoscaler minimum and maximum number of PGs for pools

Describe the task you were trying to accomplish:
- Configure autoscaler to not automatically decrease the PG count below a set value or increase PGs beyond a set value.

Suggestions for improvement:
- Add a sub-section under [3.4] that explains how to configure autoscaler with pg_num_min and pg_num_max.

- Documentation is already available upstream:
 (https://docs.ceph.com/en/latest/rados/operations/placement-groups/#autoscaling-placement-groups)
Section: SPECIFYING BOUNDS ON A POOL’S PGS

Document URL:
(https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/5/html/storage_strategies_guide/placement_groups_pgs#setting-placement-group-auto-scaling)

Chapter/Section Number and Title:
3.4. Auto-scaling placement groups
