[PVE-User] Configuring ceph storage

[Fabrizio Cuseo]

I think that is not the correct configuration; as you can see on the wiki page http://pve.proxmox.com/wiki/Storage:_Ceph , you can't use the proxmox host as part of the ceph cluster.

To resolve the issue without the need of other servers for the ceph storage, I have done this setup:

- Proxmox host A - 2 raid-1 disks with proxmox
   - 2 local disks configured as LVM local storage, not shared
   - Qemu VM with Ceph cluster server, using local proxmox storage for the OS, and the 2 LVM disk storage for Ceph storage


With 3 of theese hosts, I have:
 a full working proxmox cluster with 3 nodes
 a full working ceph cluster with 3 nodes

All the VMS that I have on the cluster can use the ceph shared storage.

I know that is not the best setup for performances, but is really ceaph.

Regards, Fabrizio

The physical proxmox nodes is also the ceph cluster node.
