The best thing is to fix the initial problem, but as a workaround you may
try to fence_node from some of the other machines in the cluster even it
has left cleanly - this should cleanup the locks held from that node

about seeing the locks you may use "gfs(2)_tool lockdump <mount_point>" or
via debugfs by mounting it somewhere
