I build next system.
DRBD 8.3.15 under CentOS5.9 (x86_64)
I conected 2 X 39TB Raid System under each DRBD system.
These Raid system has gpt partion.
(partition1 135MB partion2 39TB)
These meta-data are external.
/etc/drbd.conf is next.

# please have a a look at the example configuration file in
# /usr/share/doc/drbd82/drbd.conf
resource r0 {
  protocol C;

 net {
   sndbuf-size 512K;
   ping-int 10;
   ping-timeout 10;
   connect-int 10;
   timeout 80;
   ko-count 0;
   max-buffers 8000;
   max-epoch-size 8000;

syncer {
  rate 3000K;
  verify-alg md5;
  csums-alg md5;
  al-extents 3389;
  on centos581 {
   device     /dev/drbd0;
   disk       /dev/sdb12
   address    192.1681.56:7790;
   flexible-meta-disk /dev/sdc1;
  on centos582 {
   device     /dev/drbd0;
   disk       /dev/sdb2;
   flexible-meta-disk /dev/sdc1;

I ran drbd deamon. I checked /proc/drbd. It was fine.

I setup tgt(iscsi) .DRBD setup ISCSI tartget deviice.

tgtadm --lld iscsi --op new --mode target --tid 1 --targetname iqn.2010-09.com.hoge.alpha:testdevs
tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 --backing-store /dev/drbd0
tgtadm --lld iscsi --op bind --mode target --tid 1 --initiator-address=ALL

Next I use iscsi initiator under Windows2008R2.
Windows2008R2 and DRBD connected.
But Windows2008R2 detected DRBD iscsi target next.

Windows2008R detected DRBD iscsi target MBR device.
and Windows200R2 detected this DRBD iscsi target has 4patition.
Parition 1 800GB Partition1 258GB Partition2 258GB Patition3 12MB.
But This device using gpt partition and 2 patitions.
Partition 1 135MB Partion2 39TB

Please advice me.
