Sorry??? this three nodes are RHEL5 with lastest patches applied except 
kernel version 2.6.18-8.1.10.

Version of cman is: cman-2.0.64-1.0.1.el5
Version of gfs-utils:
Version of rgmanager: rgmanager-2.0.24-1.el5

  And fence-manual exists on this cluster suite:

[root at haldir xen]# whereis fence_manual
fence_manual: /sbin/fence_manual /usr/share/man/man8/fence_manual.8.gz
[root at haldir xen]# rpm -qf /sbin/fence_manual
[root at smeagol xen]#

And fence_ack_manual it is not a bash script, it is a binary:

[root at haldir xen]# whereis fence_ack_manual
fence_ack_manual: /sbin/fence_ack_manual 
[root at haldir xen]# cd /sbin
[root at haldir sbin]# file fence_ack_manual
fence_ack_manual: ELF 32-bit LSB executable, Intel 80386, version 1 
(SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for 
GNU/Linux 2.6.9, stripped
[root at haldir sbin]#

  Do I need to install rhel5.1 beta to do this?? If it yes i have a very 
very great problem ....
