      This is the clean way to handle this. But you can
        also use udev to do this at boot. From what I found on the
        mailing list and made working before using GUID :
        

          cat > /etc/udev/rules.d/89-ceph-journal.rules <<
            EOF
          KERNEL=="sda?" SUBSYSTEM=="block" OWNER="ceph"
            GROUP="disk" MODE="0660"
          KERNEL=="sdb?" SUBSYSTEM=="block" OWNER="ceph"
            GROUP="disk" MODE="0660"
          KERNEL=="sdc?" SUBSYSTEM=="block" OWNER="ceph"
            GROUP="disk" MODE="0660"
          EOF

             Hi,

              
              Is setting GUID is the only way to fix this ? I don't use
              GPT but MBR and I don't want to try conversion on
              production servers...

                  You should check that the owner of your
                    ceph partitions (both journal and data) is 'ceph',
                    otherwise the ceph user won't mount it.
                    

                    You can simply do : chown ceph:disk /dev/sdc3
                    

                    If this solve your issue you should set the GPT
                      GUID [1] of the partitions with a tool like sgdisk
                      to make this persistent across reboot.
                    

                    I think only your journal is affected as
                      ceph-disk does not prepare the partition (WARNING:ceph-disk:Journal

                        /dev/sdc3 was not prepared with ceph-disk.
                        Symlinking directly)
