If a node is removed from a lockspace, and then added back before the dlm is notified of the removal, the dlm will not detect the removal and won't clear the old state from the node. This is fixed by using a list of added nodes so the membership recovery can detect when a newly added node is already in the member list. Signed-off-by: David Teigland <teigland@redhat.com>
