Hi, debugging and reading more if cache=none is set this should overwrite the ceph config from rbd cache = true=> false but still this machine is consuming 20G instead of 16G

I found out that my config for rbd cache size was too big which could explain me the problem. But when i make: ceph -n mon.2 --show-config it shows me the standard config size from ceph. And also that rbd cache = false. Very strange. Is this not the way to get the running conf? My client section in the /etc/pve/ceph.conf looks like this: [client] rbd cache = true rbd cache size = 268435456 rbd cache max dirty = 33554432 rbd cache max dirty age = 3 but seems to be ignored? I am using cache=writeback and cache=none. Same results Von: pve-devel [mailto:pve-devel-boun...@pve.proxmox.com] Im Auftrag von Eneko Lacunza Gesendet: Dienstag, 18.

We have 3 small clusters using creph/rbd and I'm not seeing this. Biggest VM is 6GB of RAM though, biggest disk is 200GB and a VM has a total of 425GB in 5 disks. Are you using Proxmox Ceph Server? What cache setting in VM harddisk config?

(up to twice) which is a horror if the machines have about 15-20G but consume 30-40GB I was checking: ) all machines have the same pve packages installed ) it only happens on machines with ceph osd installed ) which also are using rbd client for virtual hdds It does not happen if they are using nfs backend for virtual hdd. Or other machines which are just using the rbd client but doent have osd's... Has somebody experienced something like this also? Any ideas how to debug further?
