Hi Nico,
What is your mon_memory_target?
Zitat von Nico Schottelius <nico.schottelius@xxxxxxxxxxx>:
Hello,
we have recently moved our ceph monitors from small, 4GB RAM servers
to big servers, because we saw memory pressure on the machines.
However even on our big machines (64GB ~ 1TB RAM) we are seeing
ceph-mon processes being killed at around 90-94GB of RAM.
Now, my understanding is that a ceph-mon should be a rather "small"
process, so allocating 90GB RAM seems to be a bit.. atypical?
This cluster runs ceph version 14.2.9
(581f22da52345dba46ee232b73b990f06029a2a0) nautilus (stable), about
90 osds, about 620TB data.
Any input is appreciated.
Best regards,
Nico
