Doc Text:
.Users can now create pools with the `--bulk` flag With this release, you can create pools with the `--bulk` flag. It uses a profile of the `pg_autoscaler` that provides better performance from the start by allocating a full complement of placement groups (PGs) and scales down the PGs only when the usage ratio across the pools is not even. If the pool does not have the `--bulk` flag, the pool starts out with minimal PGs. To create a pool with the bulk flag: .Syntax [source,subs="verbatim,quotes"] ---- ceph osd pool create _POOL_NAME_ --bulk ---- To set/unset bulk flag of existing pool: .Syntax [source,subs="verbatim,quotes"] ---- ceph osd pool set _POOL_NAME_ bulk _TRUE/FALSE/1/0_ ---- To get bulk flag of existing pool: .Syntax [source,subs="verbatim,quotes"] ---- ceph osd pool get _POOL_NAME_ bulk ----

Description of problem:
mon: osd pool create <pool-name> with --bulk flag
https://github.com/ceph/ceph/pull/44847


Version-Release number of selected component (if applicable):
RHCS 5.1

In the workload-DFG clusters, we have seen that using --bulk always helps during pool creation and it makes sure that the PG autoscaler is not reducing the pool PG count from a given pg count that has been assigned to the pool via --bulk option.
