Next time could you also collect /proc/cluster/lock_dlm/debug and /proc/cluster/dlm_debug ? I've set up a similar but simplified test on both of my test clusters (a 2-node and a 7-node). I can't dedicate these machines for a full 1-2 day stretch this until the weekend, though. My test is a loop around: - on each node sequentially: unmount/mount gfs - on each node sequentially: run some load for a couple minutes -- Dave Teigland <teigland@xxxxxxxxxx>
