I turned debug_mgr to 4/5 and found this while executing the plan. Apparently the command has error but the reply is "Success!" while nothing is done. Not sure what the 'foo' part is doing there. 2018-05-28 14:24:02.570822 7fc3f5ff7700 0 log_channel(audit) log [DBG] : from='client.282784 $IPADDRESS:0/2504876563' entity='client.admin' cmd=[{"prefix": "balancer execute", "plan": "mynewplan2", "target": ["mgr", ""]}]: dispatch

Sent: Monday, 28 May 2018 12:47:41 PM To: ceph-users Subject: Can't get ceph mgr balancer to work (Luminous 12.2.4) Hi all,
I'm testing out ceph mgr balancer as per http://docs.ceph.com/docs/master/mgr/balancer/ on our test cluster on Luminous
12.2.4, but can't seem to get it to work. Everything looks good in the prep, the new plan shows that it will take some actions, but it doesn't execute at all. Am I missing something? Details below: # ceph balancer eval
current cluster score 0.011116 (lower is better)
# ceph balancer mode upmap
# ceph balancer optimize mynewplan2
# ceph balancer status
{
"active": true,
"plans": [
"mynewplan2"
],
"mode": "upmap"
}
# ceph balancer show mynewplan2
# starting osdmap epoch 10629
# starting crush version 71
# mode upmap

# ceph balancer eval mynewplan2
plan mynewplan2 final score 0.010474 (lower is better)
# ceph balancer execute mynewplan2 (nothing happens)
# ceph balancer on (still nothing happens) Regards,
