its the drbd8.3 package from elrepo.

/etc/drbd.d/global_common.conf:

    global { usage-count no; }

    common {
             syncer { rate 200M; }
    }

/etc/drbd.d/main.res:

    resource main {

    protocol C;
    startup { wfc-timeout 0; degr-wfc-timeout 120; }
    disk { on-io-error detach; }

    syncer { verify-alg crc32c; }

    on sg1.domain.com {
             device /dev/drbd0;
             disk /dev/vg_sg1data/lvdata;
             meta-disk internal;
             address 10.5.160.70:7788;
             }

    on sg2.domain.com {
             device /dev/drbd0;
             disk /dev/vg_sg2data/lvcopy;
             meta-disk internal;
             address 10.5.160.71:7788;
