Hi,
i read a little on the web but I would like to be sure of this change.
I have a 3 node cluster with ceph and it works as an external strorage, so it doesn't have any vm.
I would like to increase the ram to 8gb for osd and I have read that you need to add these lines in ceph.conf
[osd]
osd memory target = 8589934592
Each node is 128gb of ram and mounts 6 disk 4tb ssd
The servers are dell and the disks are under perc controller with raid0 for each disk.
In the crush map they are seen as hdd
Is it possible to make this change in production without interruption?
Regards
