 drbdadm disconnect r1

Command 'drbdsetup 1 disconnect' did not terminate within 5 seconds
root at pro01:~# No response from the DRBD driver! Is the module loaded?

from this host can ping to node, but not telnet IP PORT_DRBD

telnet 5.39.69.152 7791
Trying 5.39.69.152...
telnet: Unable to connect to remote host: Connection refused


Of course, on both nodes IP form each node it's on Firewall.


Only reboot machine solvent a problem.

Desesperate.
