Run this command: drbdadm create-md export<BR>

><BR>
<BR>
From the drbd.conf, it is clear that you are using external device <BR>
for metadata. You can make it to internal by replacing the line<BR>
<BR>
meta-disk /dev/hda6[0];<BR>
with<BR>
meta-disk internal;<BR>
<BR>
on both master and slave. But, in this case, DRBD stores meta-data<BR>
information on the same physical lower-level device(/dev/hda5 in your<BR>
case) as the actual data.<BR>
<BR>
<BR>
> 3.How can i view my meta-data?<BR>

<BR>
Refer drbdmeta command <BR>

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.<BR>
