[metti-himself]

Is this a bug report or feature request?

• Bug Report
  Im trying to fix a health Warning:

HEALTH_WARN 1 pools have many more objects per pg than average
MANY_OBJECTS_PER_PG 1 pools have many more objects per pg than average

ceph tell mon.* injectargs '--mon_pg_warn_max_object_skew -1'
mon.e: injectargs:mon_pg_warn_max_object_skew = '-1.000000' (not observed, change may require restart) 
mon.f: injectargs:mon_pg_warn_max_object_skew = '-1.000000' (not observed, change may require restart) 
mon.h: injectargs:mon_pg_warn_max_object_skew = '-1.000000' (not observed, change may require restart)

File(s) to submit:

• Cluster CR (custom resource), typically called cluster.yaml, if necessary
• Operator's logs, if necessary

• Crashing pod(s) logs, if necessary

  To get logs, use kubectl -n <namespace> logs <pod name>
  When pasting logs, always surround them with backticks or use the insert code button from the Github UI.
  Read Github documentation if you need help.

Environment:

• CentOS 7
• 5.3.9
• Custom Bare Metal Setup (1 Master + 3 Worker)
• v1.1.2
• Storage backend version (e.g. for ceph do ceph -v): ceph version 14.2.1
• Kubernetes version (use kubectl version): v1.15.3
• Kubernetes cluster type (e.g. Tectonic, GKE, OpenShift): Baremetal
• Storage backend status (e.g. for Ceph use ceph health in the Rook Ceph toolbox):
  ceph health
  HEALTH_WARN 1 pools have many more objects per pg than average

Use ceph config set command instead.

Use ceph config set command instead.

This fixed it: ceph config set mgr mon_pg_warn_max_object_skew 0

Thanks!
