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 osd pg-upmap-items 10.3 15 5 33 45 62 58
ceph osd pg-upmap-items 10.8 41 45 13 5
ceph osd pg-upmap-items 10.b 17 18 41 45 13 5
ceph osd pg-upmap-items 10.10 27 28
ceph osd pg-upmap-items 10.11 51 58
ceph osd pg-upmap-items 10.2a 32 45 27 21
ceph osd pg-upmap-items 10.32 40 45 7 5 51 58
ceph osd pg-upmap-items 10.47 43 45 51 58
ceph osd pg-upmap-items 10.4c 4 5 51 54
ceph osd pg-upmap-items 10.61 51 54
# 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,
Linh
