    Hi,

        I have a production Ceph Cluster
        - 3 nodes

        
        - 3 mons on each nodes
        - 9 OSD @ 4TB per node
        - using ceph version 0.80.5
          (38b73c67d375a2552d8ed67843c8a65c2c0feba6)
        

          Now I want to upgrade it to Hammer, I saw
            the documentation on upgrading, it looks straight forward,
            but I want to know to those who have tried upgrading a
            production environment, any precautions, caveats,
            preparation that I need to do before doing it?
          

    Our migration on 3 Proxmox nodes with 3x3 OSD disks, went really
    smooth. :)

    
    We were running lastest Firefly, I suggest you first upgrade to
    latest Firefly too.

    
    Cheers

    Eneko
