I have similar problem on my two nodes cluster used as GFS2
storage cluster. Just GFS2 not service clustering. Both nodes were
hanging several times and we had to reboot . They are running
webservers. I have been in contact with Redhat and I was advised to use
gfs2_hangalyzer during the next IO or process hang. The Redhat
support engineer is assuming it is a lock contention issue, and on your
case you said only your developers can solve this type of problem. What
do you mean by that ? Can you make it a little bit clear for me. You
mean the problem is caused by applications running in your servers ? In
our case we have Java and Tomcat are running, you mean the Java
developers should see the matter ?
By the way I just subscribed to the linux-cluster redhat com now, is this
correct way to post messages ?
Very wel, now i make a deep analysis, but i think thath the
problemi s simply the conteention, so only our developers can solve the
