[Miguel Angel Guerrero]

Hi the next are my drbd.conf


global {
    usage-count no;
}
common {
    protocol C;

    syncer {
        rate 100M;
        al-extents 3389;
    }
     disk {

    fencing resource-and-stonith;
    }

    handlers {
        outdate-peer "/usr/sbin/rhcs_fence";
    }

    net {
        sndbuf-size 1024k;
        allow-two-primaries;
after-sb-0pri discard-zero-changes;
after-sb-1pri discard-secondary;
after-sb-2pri disconnect;
}
    startup {
        become-primary-on both;
    }

}
resource wsg_db {
    device /dev/drbd0;
    meta-disk internal;

    on wsguardian1 {
        address 192.168.253.1:7788;
disk /dev/rootvg/wsg_data_lv;
    }
    on wsguardian2 {
        address 192.168.253.2:7788;
