Thanks for reply Andrew,
ok, then how openais-pacemaker cluster handles the cluster whose nodes span

Thanks a lot Andrew for your reply,
i have another question on stonith. i have configured sbd stonith and riloe
stonith. can i set the order of execution. say i want riloe to get executed
first and if it fails then sbd to get executed. should i set priority??
it seems to me that suse 11 follows
can we use SBD stonith to solve this issue.

Hi All,
do we have any way to encapsulate more than one resource into one . suppose
i have a lvm resource, ip add resource so can i combine both? i know that
we can set constraint to make them dependent on each other but do we have
any other way.
second question i have , is there any way to kill
activate the VG during
resource start up??

Hi All,
i have just configured LVM resouce agent in pacemaker cluster. i am kind of
suprised as it is not taking care of exclusive activation.
am i missing something or LVM Resouce agent is written in this way only. can
anyone put some light here.

Hi All,
pacemaker has one property "on_fail" for any operation configured for a
resource. suppose i have set "on_fail" to "fence" for a monitor operation ,
then is it expected to fence the node in case of resource monitor failure
?? can any one explain please.
