To fix the nearfull warn, I am reducing the weight of a specific OSD,
which filled >85%..
Is this work-around advisable?
Sure. This is what reweight-by-utilization does for you, but automatically. sage
Thanks

Hi Sage,
Jewel and the latest hammer point release have an improved
reweight-by-utilization (ceph osd test-reweight-by-utilization ... to dry
run) to correct this.
Thank you....But not planning to upgrade the cluster soon.
So, in this case - are there any tunable options will help? like
"crush tunable optimal" or so?
OR any other configuration options change will help?
Firefly also has reweight-by-utilization... it's just a bit less friendly
than the newer versions. CRUSH tunables don't generally help here unless
you have lots of OSDs that are down+out.
Note that firefly is no longer supported.

Hello,
I have aorund 100 OSDs in my ceph cluster. In this a few OSDs filled
with >85% of data and few OSDs filled with ~60%-70% of data.
Any reason why the unevenly OSDs filling happned? do I need to any
tweaks on configuration to fix the above? Please advise.
PS: Ceph version is - 0.80.7
