Ok, perhaps it was my fault understanding man page.
It seems that when you use meta-disk you have to use index and in that
case you need at least 256MB????
Initially I used
meta-disk  /dev/cciss/c0d0p4;

but I got a syntax error about
expected [ instead of ;
so I assumed that it is mandatory to use the index.... but probably it
is not the case?

Anyway I configured flexible-meta-disk instead of meta-disk

flexible-meta-disk  /dev/cciss/c0d0p4;
instead of
meta-disk  /dev/cciss/c0d0p4[0];

And now I  'm able to run (after recreating meta device):
[root at virtfed ~]# drbdadm up r0
[root at virtfed ~]# echo $?
0
[root at virtfed ~]# cat /proc/drbd
