[SOLVED] can i make two separate cluster ?

[ilia987]

i want to make two separate clusters, i already have one ssd based for production,
and i want to make one more, hdd based for backup and slow storage

Within the same network, you mean? Yes, that should not be a problem.

Otherwise please provide more information what you want to achieve

You can setup your OSDs the way you want and then would have to manage the volumes on those OSDs accordingly. You will not get two clusters, but a cluster with two volumes. If you really wanted another cluster, then you'd have to throw in more hosts.

i dont want to add hostes, just to add hdds and make second volume
one for ssd (already exists) and one for hdd

i would like to add another volume (the same as "default")

Ah, a Ceph Cluster. If you want another pool that will use the slow HDDs have a look at device classes in the CRUSH map. https://pve.proxmox.com/pve-docs/pve-admin-guide.html#pve_ceph_device_classes
