Multi Ceph Cluster or Pool from Specific OSD

[ertanerbek]

Hi All,

I have many diffrent type disk on my servers and I was use GlusterFS in past also will continue anyway... Bu I want sparate my some disk for Ceph test but I want create two pool from may some SSD ( NVME ) and SAS disk... For Ceph; multi cluster possible but I think we can not manage on Proxmox ( can we ? ) or can we select OSD which I want use on diffrent pool ? for example SSD Pool from SSD disk, SAS pool from SAS disk is this possible ?
