 Clone Set: cloneDLM [resDLM]

 Clone Set: cloneGFSD [resGFSD]
     Started: [ fix foxy ]

==[ALL] Configure drbd==
On both nodes create file /etc/drbd.d/disk0.res containing:
 resource disk0 {
          protocol C;
         net {
                 cram-hmac-alg sha1;
                 shared-secret "lucid";
                 allow-two-primaries;
                 after-sb-0pri discard-zero-changes;
                 after-sb-1pri discard-secondary;
                 after-sb-2pri disconnect;
     }
         startup {
                 become-primary-on both;
        }
        on fix {
                device /dev/drbd0;
                disk /dev/sda3;
                address 10.168.244.161:7788;
                meta-disk internal;
        }
        on foxy {
                device /dev/drbd0;
                disk /dev/sda3;
                address 10.168.244.162:7788;
                meta-disk internal;
        }
 }
Pacemaker will handle starting and stopping drbd services, so remove its init script:

 sudo update-rc.d -f drbd remove

==[ALL] Prepare partitions==
erasing is not always necessary
 dd if=/dev/zero of=/dev/sda3

Create drbd resource:
 sudo drbdadm create-md disk0
 You should get:

 Writing meta data...
 initializing activity log
 NOT initialized bitmap
 New drbd meta data block successfully created.
 success
Start drbd:
 sudo service drbd start

==[ALL]Set up dlm_controld and gfs2 with drbd==
