Issue with RGMANAGER After upgrade 2.3 - 3.0

Hi, I upgrade form 2.3 to 3.0 and now I have a problem with rgmanager.

If I try to install a new cluster.conf I cant :( and If I tried to use "fence_tool leave" I obtain that report:

found dlm lockspace /sys/kernel/dlm/rgmanagerfence_tool: cannot leave due to active systems



What do you recommend to do?

Thanks.
