Hi all,
we are running a 144 osds ceph cluster and a couple of osd are >80% full.
This is the general situation:
osdmap e29344: 144 osds: 144 up, 144 in
pgmap v48302229: 42064 pgs, 18 pools, 60132 GB data, 15483 kobjects
173 TB used, 90238 GB / 261 TB avail
We are currenty mitigating the problem using osd reweight but the more
we read about this problem the more our doubts abouts using osd crush
reweight increases.
Actually, we do not have plans to buy new hardware.
Our main question is: what if the re-weighted osd restart and get the
original weight are the data going back?
How to correcly face this kind of situation?
Many thanks
Simone
