Figure out which OSDs are too full:
ceph osd df tree
Then you can either reduce their weight:
ceph osd reweight <id> 0.9
Or increase the threshhold after which an OSD is considered too full for backfills.
How this is configured depends on the version, i think in your version it is still
ceph pg set_backfillfull_ratio 0.XX
It's probably currently configured to 0.85

Hi Guys,
i've inherited a CephFS-Cluster, I'm fairly new to CephFS.
The Cluster was down and I managed somehow to bring it up again.
But now there are some Problems that I can't fix that easily.
This is what 'ceph -s' is giving me as Info:
[root@pcl241 ceph]# ceph -s

Could someone please put me in the right Direction about what to do to fix the Problems?
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.
Thanks in Advance,
Steininger Herbert
