Hi Dejan,
Thanks for the info.
Please correct me if my below understanding is wrong??
With the clone, we can work out a active/active model as i understood from
Pacemaker guide.
Isn't that hot standby mode?
So the resources would be up and running on both nodes.
In my setup, I am unable to just a
Thank you for the prompt response!
I am new in HA but I learn fast :)
Anycase, due to luck of time we must start without a fencing device and only
network. Is it possible with Pacemaker? In the next release we will add fencing.
Can you send me link to doc?
BTW, may be you know if the first versio

it but ca
Hi Dejan,
thanks for answering. I'll have a look at it and
will see whether sets fit our needs better.
Have a nice weekend.
Best regards

If you need both, then groups are fine.

Hi Dejan,
Thanks for the response.
In our setup, we want the resources to start on the 2 nodes (active/active)
so that the downtime would be less.
All clients connect to the VIP. If the resource on any one node goes down,
I expect the VIP should be moved to another node and since the resource is
It is possible in the same way that it is possible to drive on the
highway without your seatbelt. First time something goes wrong though,
you are in deep trouble. The biggest risk is a node that locks up but
doesn't die. Any network based "detection" will not be able to tell the
difference betw
Hi Dejan,
we need colocation and order constraints.
IMHO it's an use case for sets, but I have to admit
that I don't really understand how to configure them
with crm. A group gives a group resource id which I
can use as reference in the contraints. It makes the
config simple.

Dear Pacemaker community!
I want to install 2 Centos machines and to
configure HA using one virtual IP.
I do not want to use power card or something like this.
I want to use communication to determine the failing of nodes: broadcast /
mulicast UDP / TCP.
But I am confused if it possible.

Hi, Andrew
I implemented the function which changes a display option during
operation of crm_mon.
If this function is used, the time and effort which changes an option
and reboots crm_mon can be saved.
Furthermore, I extended the function from now on and think that he

Hi All,
I am trying to run same RA on both nodes using clone.
My set up is a 2 node cluster with HB+pacemaker.
The RA aren't started automatically.
They are started through pacemaker only.
