Hi,
is the balancer on? And which mode is enabled?
ceph balancer status
You definitely should split PGs, aim at 100 - 150 PGs per OSD at
first. I would inspect the PG sizes of the new OSDs:
ceph pg ls-by-osd 288 (column BYTES)
and compare them with older OSDs. If you have very large PG sizes,
only a few of them could fill up an OSD quite quickly since your OSD
sizes are "only" 1.7 TB.
Zitat von Yunus Emre Sarıpınar <yunusemresaripinar@xxxxxxxxx>:
I have 6 ssd sata and 12 osd per server in a 24 server cluster. This
environment was created when it was in the natilus version.
I switched this environment to the Octopus version 6 months ago. The
cluster is working healthily.
I added 8 new servers, I created 6 ssd sata and 12 osd on these servers in
the same way.
I did not change the number of PGs in the environment, I have 8192 PGs.
The problem is that in my ceph -s output, the remapped pg and missplaced
object states are gone, but there is a warning of 6nearfull osds and 4pools
nearfull.
I saw in the ceph df output that my pools are also full above normal.
In the output of the ceph osd df tree command, I observed that the
occupancy percentages of the newly added osds were around 80%, while the
percentages of the old osds were around 30%.
How do I equalize this situation?
Note: I am sharing the output of crushmap and osd df tree with you in the
attachment.
My new osds between 288-384.
My new servers are ekuark13,14,15,16 and bkuark13,14,15,16.
