Hello,
We have a Nautilus cluster exhibiting what looks like this bug:
https://tracker.ceph.com/issues/39618
No matter what is set as the osd_memory_target (currently 2147483648 ),
each OSD process will surpass this value and peak around ~4.0GB then
eventually start using swap. Cluster stays stable for about a week and
then starts running into OOM issues, kills off OSDs and requires a
reboot of each node to get back to a stable state.
Has anyone run into similar/workarounds ?
Ceph version: 14.2.1, RGW Clients
CentOS Linux release 7.6.1810 (Core)
Kernel: 3.10.0-957.12.1.el7.x86_64
256GB RAM per OSD node, 60 OSD's in each node.
Thanks,
--
Brett Kelly
