</div>Pacemaker isn't doing anything, it just calls the scripts you tell it.<br></blockquote><div><br>I know, I have stepped through the script and have not found anything out of the ordinary. But I still have the problem that when pacemaker starts the nfs daemons they cannot be killed without using -9. So something is going on that I cannot figure out. I was just hoping that someone else has seen this issue before and figured out what was going on.<br>
