[Pacemaker] drbd outdate peer

[Fausto Lombardi]

This is ha.cf file:

debugfile /var/log/ha-debug
logfile    /var/log/ha-log
logfacility    none
bcast eth0 eth1
auto_failback on
node centos-xen1 centos-xen2
respawn root /usr/lib64/heartbeat/mgmtd -v
respawn root /usr/lib64/heartbeat/dopd
apiauth mgmtd uid=root
apiauth dopd uid=root
crm yes


and this the drbd.conf file:

global { usage-count no; }

common { syncer { rate 10M; verify-alg md5; } }

resource r1 {
    protocol C;

    startup {wfc-timeout 60;
      degr-wfc-timeout 50;
    }

  disk { on-io-error detach;
     fencing resource-only;
    }

  handlers {
    outdate-peer "/usr/lib64/heartbeat/drbd-peer-outdater";
       }


    on centos-xen1 {
    device    /dev/drbd1;
    disk      /dev/sda3;
    address   172.16.0.1:7789;
    meta-disk internal;
    }

    on centos-xen2 {
    device    /dev/drbd1;
        disk      /dev/hda3;
        address   172.16.0.2:7789;
        meta-disk internal;
      }
}

And then this is what I say in the messages

time.
