Hi,all
I have defined a fence resource ,and cloned it.But when a node becomes
UNCLEAN(I disconneted its network),the fence action will be executed

Hi!
Is it possible to set something like started-weight score for a
resource? Or make resource stop instead of migrating elsewhere (and take
all the resources it's colocated with)? (That would be the same as
setting resource stickiness = started-weight.)
I have a spam filter that sometimes fails
Is fencing/stonith configured in pacemaker? Can you call a fence against
a peer in pacemaker and trigger a reboot of the target node? If that
doesn't work, then you don't have proper fencing in pacemaker and the
crm-fence-peer.sh hook script won't work.
So yes, you need stonith and you need to mak
Hi Digimer,
I am already using crm-fence-peer.sh
resource r8 {
handlers {
fence-peer "/usr/lib/drbd/crm-fence-peer.sh";
after-resync-target "/usr/lib/drbd/crm-unfence-peer.sh";
split-brain "/usr/lib/drbd/notify-split-brain.sh root";
}
Is Stonith still necessary? How do I configure it

Hi Soni,
I did these configurations on my DRBD and the correct recovery of
split-brain worked well.

I understood that is not possible if I don't have a connection back-to-back

But I am thinking to create a script that do that for me.

Well, not accurate unless they consider the crm interface as making manual
changes. I do not see those errors anymore after rebooting the machines.
Things are (almost) all working now.

Thank you, thank you, thank you. I was chasing that problem for several
days. I did not see anything in any of the logs that pointed to where the
problem might be. Now I see that there is something about that requirement
on the linux-ha ocf_heartbeat_apache page. Thanks again.

Oops, I haven't have my coffee yet this morning... I see you've written
your own RA rather than using the existing ones, my apologies for the noise
on the list.
