Hi
Yesterday we observed that drbd was completely locked (in kernel
thread?). All drbdsetup commands blocked and were not executed. This was
after a short network failure. The drbd log is below. Some other running
processes like squid where also locked, didn't work anymore and could
not be killed and restarted.
We are using drbd-0.7.14

Anyone seen this before? Could this be fixed in a more recent drbd version?
