External Ceph Pool size limit and best practice

[koniambo]

Hi,

Im testing proxmox with an external ceph in a lab
I wanted to know if it's possible to show the real max_size of a ceph pool in proxmox storage (which is 100GiB) instead of the entire size of my cluster ?

Do you know any good practice concerning pool separation between VM, do I have to create 1 pool per OS or 1 pool for the entire proxmox and then few namespace for each type ?

Thanks for your help !

IMHO you do not need pool separation between VMs for security reasons. You may want to configure multiple pools for quota or multiple Proxmox clusters. Or if you want to set defferent permissions for users in Proxmox.

AFAIK Proxmox does not show the quota max_size value.

Thought it would be easiest to administrate pools by spreading VMs in a few pools, or to change some configuration about I/O regarding needs of every VMs

Thanks for your answer !
