Hi Massimo!
What version of Ceph is in use?
Thanks,

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:
