Subject: Problems creating a balancer plan

 

Hi

I already used the balancer in my ceph luminous cluster a while ago when all the OSDs were using filestore.

Now, after having added some bluestore OSDs, if I try to create a plan:

[root@ceph-mon-01 ~]# ceph balancer status

{

    "active": false, 

    "plans": [], 

    "mode": "crush-compat"

}

[root@ceph-mon-01 ~]# ceph balancer eval

current cluster score 0.051599 (lower is better)

[root@ceph-mon-01 ~]# ceph balancer optimize 01-march-2019

Error EINVAL: Traceback (most recent call last):

  File "/usr/lib64/ceph/mgr/balancer/module.py", line 340, in handle_command

    r, detail = self.optimize(plan)

  File "/usr/lib64/ceph/mgr/balancer/module.py", line 670, in optimize

    return self.do_crush_compat(plan)

  File "/usr/lib64/ceph/mgr/balancer/module.py", line 814, in do_crush_compat

    weight = best_ws[osd]

KeyError: (64,)

This is what I see in the mgr log:
