Hello,
'cat /proc/drbd' can overwrites drbd_conf[minor].o_state in some cases.
(Thus drbd_conf[minor].o_state remains "Unknown", even it's
"Secondary").

Look:

Node1 (primary) : insmod drbd
Node1: drbdsetup disk /dev/hdc5
Node1: drbdsetup net 136.10.15.110 136.10.15.120 C
/*Now we do many cat /proc/drbd when Node2 will connect*/
Node1: while true; do cat /proc/drbd > result; done

Node2 (Secondary) : insmod drbd
Node2: drbdsetup disk /dev/hdc6
Node2: drbdsetup net 136.10.15.120 136.10.15.110 C

Node1: cat result

It should be "Secondary" instead of "Unknown" !!!!

-->"Secondary" have been overwritten by "cat /proc/drbd" when secondary
connected.<--
