Thanks Guys, I was out of Office, I will try your suggestions and get back to you.
And extending the Cluster is something that I will do in the near Future, I just thought it would be better to get the Cluster Health back to “Normal” first.

Paul has sent you some hints. Jewel Documentation: http://docs.ceph.com/docs/jewel/rados/ osd backfill full ratio Description: Refuse to accept backfill requests when the Ceph OSD Daemon’s full ratio is above this value. Type: Float Default: 0.85 You could put this into your config with an value of 0.9 on all osd-servers and restart the osd-daemons. Don't forget "ceph osd set noout". After restarting the daemons "ceph osd unset noout" resync should take place instandly. Now set reweight on osd 1,0,2 to a value like 0.9. "ceph osd reweight 1 0.9" and so on. Herbert, you really should extend your cluster! And Or evacuate your data and rebuild it from scratch. Cheers, Vadim On 12.06.2018 16:42, Steininger, Herbert wrote: Hi, Thanks Guys for your Answers.

It seems that two OSD are full, but how can I solve that, if I don't have additionally hardware available? Also it seems that the Cluster has different ceph-versions running (Hammer and Jewel), how to solve that? Ceph-(mds/-mon/-osd) is running on Scientific Linux. If more Info is needed, just let me know.
