From the drbd.conf, it is clear that you are using external device
for metadata. You can make it to internal by replacing the line
meta-disk /dev/hda6[0];
with
meta-disk internal;
on both master and slave. But, in this case, DRBD stores meta-data
information on the same physical lower-level device(/dev/hda5 in your
case) as the actual data.

Refer drbdmeta command

Online device verification feature is available only from 8.2.4 onwards. The build which you are using is very old. Download the latest version.
