Hi!
Try corosync-objctl runtime.totem.pg.mrp.srp.members. You should see
something like:
Actually (honestly!) this command does not return anything. For corosync-objctl
I can see a whole lot of objects of the type/class runtime.totem.pg.mrp, but
none of the type members.

Hi!
In one of my clusters I disconnect one of the nodes (say app01) from the
network. App02 takes of the resources as it should. Nice.
When I reconnect app01 to the network, crm_mon on app01 continues to report
app02 as offline and crm_mon on app02 does the same for app01. Still, no
errors are

I configured my nodes *not* to auto failback after a defective node comes back
online. This worked nicely for a while, but now it doesn't (and, honestly, I do
not know what was changed in the meantime).

Hi!
I've two cluster-nodes, both running pingd (as a clone), to keep ressources
from starting on nodes which have not obvious connection to the network. The
ping-nodes are:

-appl02 (10.10.10.203)

Hi Lars,
Hi Lars!
You are exercising complete cluster communication loss.
Which is cluster split brain.
Correct, yes.
If you are specifically exercising cluster split brain, why are you surprised
that you get exactly that?
Because ping(d) is supposed to keep ressources from starting on
Hi Andrew,
According to your configuration, it can be up to 60s before we'll detect a
change in external connectivity.
Thats plenty of time for the cluster to start resources.
Maybe shortening the monitor interval will help you.
TNX for the suggestion, I'll try that. Any suggestions on

We've got a pretty straightforward and easy configuration:
Corosync 1.2.1 / Pacemaker 2.0.0 on OpenSuSE 11.3 running DRBD (M/S), Ping

the datafiles of mysql reside on the DRBD). The cluster consists of two

I asked the same question some time ago and received no suitable answer so far.
DRBD [1] does no proper replication over three nodes; it's basically still a
Two-Node-RAID-1 with a third node, which doesn't really take part in the
cluster but receives replication data as kind of a

Hi there,
is it possible to exchange a complete CIB with an other CIB?
The background is, that we have to roll out the same cluster in different
customer enviroments with different IPs / networks.
Instead of manipulating the CIB by hand via CRM, I'd rather replace

I conentrate both your answers into one mail, I hope that's allright for you.
For now, I need an interim solution, which is, as of now, stonith via

remaining nodes have no way to verify that the fencing
Hi!
I still have problems getting apache up and running via pacemaker.
To do some bugtracking, I tried to figure out how and when the script
/usr/lib/ocf/resource.d/heartbeat/apache is called.
Strangely, it doesn't seem to be called with the start-Parameter at all.

Hi!
TNX for your answer. We will switch to sbd after the shared storage has been
set up.
For now, I need an interim solution, which is, as of now, stonith via suicide.
My configuration doesn't work, though.
I tried:

By the way:
stonith -t suicide -T off mgmt03
works nicely. Thus the command itself is working.

Hello!
I'm currently looking for a suitable stonith solution for our environment:
1. We have three cluster nodes running OpenSuSE 10.3 with corosync and

2. The nodes reside on two VMware ESXi-Servers ( v. 4.1.0) in two locations,
where one VMware Server hosts two, the other hosts

Thank you Dominik. dopd works just fine in heartbeat 2.1.3-21.1
toghether with drbd 8.2.5-3 and solved our problem.

Hi there!
I have set up a two-node heartbeat cluster running
apache and drbd.
Everthing went fine, till we tested a split brain
scenario. In this case, when we detach both network
cables from one host, we get a two-primary situation.
