I don't see anything wrong in the lockdumps you gave, although I'm not an
expert at interpreting gfs lockdumps. Could you do a ps showing the wchan
for those processes? Using sysrq to get a stack dump would also be useful.
You might also do a dlm lock dump and pick out those locks:
echo "lockspace name" >> /proc/cluster/dlm_locks
cat /proc/cluster/dlm_locks
I/O stuck in gnbd could also be a problem, I'm not sure what the signs of
that might be apart from possibly the wchan.
