Hi,
have a config with 2 nodes where glusterfs is being mounted to root dir
of apache. After producing a kernel panic by echo c >
/proc/sysrq-trigger on node2, node 2 is turned off by stonith. The
problem is that apache cannot start because glusterfs is locking the
volume for almost 1minute. Thus pacemaker marks the resource with a
score of -INF to prevent it from starting again. After it's unlocked I
need to manually cleanup the resources (to set the score on 0)and start
apache again.
Why is glusterfs locking so long is there a possibility to reduce the
lock-time?
Below the logs
