Hi,
This is mainly due to clvmd init script that activates all the VG's it finds.
I kind off have a problem with all those init scripts (including rc.sysinit) that want to automatically do things
that an admin (well myself ;-) ) wouldn't like them to be active.
Ideally, there should be a file (/etc/sysconfig/clvm.conf) that contains only what we want to automatically activate at startup. If empty everythings gets activated.
I have the same problem with automatic cluster startup, it is something that, IMHO, could lead to undesirable situations (imagine the node that keeps on rebooting after automatic join the cluster).

I understand this is a problem to implement the exclusive activation, as it should work in the opposite way, all logical volumes should be deactivated until the resource taking care of it is started in a node where it'd be exclusively activated.

To use the lvm-cluster.sh resource script, you need to:
1.- Configure your cluster.conf file to use this new resource script.
2.- Start cluster services CMAN and CLVMD, but do not start RGMANAGER
3.- By hand, deactivate all the Logical Volumes you have configured to
be used with the "exclusive" flag. This can be done with "lvchange -an
volgrp01/logvol01"
4.- After that, you can start the RGMANAGER service. Now it should find
all the volumes deactivated and they can be activated with the exclusive
flag.
This instructions are not provided with the script because i was waiting
some kind of "information requests" by the CMAN project managers, in
wich i would detail this kind of information.
I hope this helps, please let me know if you find any problems.
Cheers,
Rafael
