I did it. The output on console is below!!
[root#] cat /proc/drbd
              : <trim>
0: cs:StandAlone ro:Primary/Unknown ds:UpToDate/DUnknown   r-----
    ns:138734606 nr:0 dw:1715987995 dr:1159763787 al:31373043 bm:12020785
lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:1740
              : <trim>

It seems to be "Primary UpToDate".

Can you paste the output of 'cat /proc/drbd' from the machine you are trying
to detach? If the peer is not UpToDate and Primary, then it needs the local
machine to run. (Just a guess, /proc/drbd will give better indication).
