[pve-devel] memory consumption

[Eneko Lacunza]

Hi Philipp,

What Ceph packages?

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?

Cheers
Eneko
