[DRBD-user] Commands freeze when accessing drbd device.

[Francis SOUYRI]

Hello,

When I try to access a drbd device, the command used freeze like that:

[root at noeud1 ~]# drbdsetup /dev/drbd0 primary --do-what-I-say
[root at noeud1 ~]# dd if=/dev/zero of=/dev/drbd0
dd: writing to `/dev/drbd0': No space left on device
262145+0 records in
262144+0 records out
**** no return ****

I have the same problem with the mke2fs command, when the two node are 
in sync and with the drbd 0.7.14...
I have some clusters with the drbd 0.7.14 with the linux kernel 
2.6.14-1.1653_FC4 (previous) that do not have this problem.

[root at noeud1 ~]# uname -a;cat /proc/drbd

Thank you for your help.
