oh, I have probably misunderstood the problem - the real cause seems be
unsynchronized local clocks on the nodes...

hello,
I have two_node cluster. If I synchronize the boot to the same time,
both nodes join fain and everything works.
I am trying to make it less sensitive to boot-time synchronization (to
accept at least two minutes difference) but the nodes never join and
after some time, one node is fenced.
I have prolonged the post_join_delay to 120 seconds, but even when both
nodes are trying to join in the nearly same time (~30 sec difference),
they are unsuccessful - the log shows
"not a cluster member after 120 sec post_join_delay"
and the other node is fenced.
I am running the cluster in following steps:
cman_tool -t 120 -w join -n node1 -c cluster
groupd
fenced
dlm_controld
gfs_controld
fence_tool -w -t 300 -m 20 join
how can I make the nodes less sensitive to boot synchronization?
thanks for your advices.
