Re: [ceph-users] Problems with CephFS
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.

Re: [ceph-users] Problems with CephFS
Well Herbert,
as Paul mentioned. You should reconfigure the threshold of your osds
first and reweight second. 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

Re: [ceph-users] Problems with CephFS
Figure out which OSDs are too full:
ceph osd df tree
Then you can either reduce their weight:
ceph osd reweight 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

Re: [ceph-users] Problems with CephFS
Hi Herbert,
could you please run "ceph osd df"?
Cheers,
Vadim

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:

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
