Hi Bart,
my guess is that you did forget the start-delay attribute for the monitor
operations, that's why you see the time-out error message.
Here is an example:
op monitor interval=20 role=Slave timeout=20
start-delay=1m \
op monitor interval=10 role=Master timeout=20
Hi Martin,
I don't have a big cluster but I do have a few (5-15) active/passive
clusters with each having 2 nodes.
I have a similar setup running : one 6 node cluster with 3 active/passive
pairs and it is working fine.
When you add more node configuration will get a bit long and unclear but
Hi Sebastian,
Do you have any experiences with the libvirt? It sounds very
promising to me. Normally a simple soap call to reboot the guest
would be enough to have kind of stonith.
I have some experiences with libvirt, but not yet with the ESX
hypervisordriver. However with that driver

stonith for vmware guests or maybe there is another solution to
build a reliable virtual cluster.

Hi Aleksey,
Don't know much about SuSEfirewall2, but can't see how when it
starts should influence the cluster, as long as it lets the
traffic we need through.
And what to do?
First of all check the logs (/var/log/messages and /var/log/firewall).
When you can't see anything suspicious, I

Hi Sandor,
1. If I migrate apache-group resorce to another node then nfs_client
won't release the /mnt mount point (I know according to this config it
should not).
Refering to teh time-out message below, is it possible that stopping the
nfs-client takes more than 20 sec?
Perhaps you should
Hi,
I have a non-symmetric cluster (symmetric-cluster=false) with four
nodes.
We still check _every_ node to be sure the resources aren't already
running there.
OK, that is reasonable - but I have trouble with the logic of the
messages: they are listed as failed actions, however if the
Hi,
I have a non-symmetric cluster (symmetric-cluster=false) with four
nodes.
On two nodes I have allowed a resource group:
location grpFS-pref1 grpFS 200: wdf-ux-0040
location grpFS-pref2 grpFS 200: wdf-ux-0041
grpFS is configured as:
group grpFS resFS resVIP resAPP

Hi Gerry,
Stop all resources running on the node going to be shut down.
That's what you want in the end, isn't it?
That should also work: set the second node to standby and do the reboot on
the primary - when primary is up again you'll set the secondary back
online.
Best,

Hi,
first of all: the succesful redesign of the clusterlabs website looks very
nice and the splash page is a really good idea!
However I found some small teething troubles:
* Explore tab:
- The link Site updates is not working yet.
- I would also suggest to add a direct link to the wiki (Home)
Hi there,
I want to realize a rather complex setup, so I have a couple of questions:
The cluster (as a shared nothing variant) should provide:
* 4 services (=server) depending on each other.
* 3 of them can only be realized as active/passive failover, synched with
DRBD (M/S)
* The servers
Hi all,
I am setting up a pacemaker (1.0.7) cluster (corosync) with centos-5.4 - I
used the repo: http://www.clusterlabs.org/rpm/epel-5/i386/. However I
can't find the rpms for the Python GUI.
Is there a rpm build for epel-5 or do I have to compile from source?
If yes - which version of

- cibadmin -C --xml-file backupfile.xml
This is a way, but maybe not the best?
I found this a convenient way:
- crm configure show backup_config.xml
- crash!!
- cibadmin -E --force
- edit configuration to delete last-lrm-refresh etc.
- crm configure backup_config.xml

Hi List,
we would like to use a python script as an OCF resource agent script.
Do you know any free templates for this?
Are there any disadvantages to consider when not using bash as a script
language for OCF?
Thanks in advance,

Hi Dimitar,
I need to publish certain resource states in my cluster through
a web interface which can be accessed remotely by load
balancers and other health-checking software. Is there a
standard way to do this?
The standard way should be SNMP- nearly every health-checking software
Hi All,
I want to be able to configure the CIB of a heartbeat/pacemaker cluster
programmatically (Java).
I don't want to reinvent the PythonGUI - I just want to be able to change
some basic settings like the Virtual-IP Address (i.e. changing resource's
attributes), set a node to standby or
