Hi All,
I have a 3 node setup with heartbeat+pacemaker.
After some time I observed that "Current DC:" keeps on changing between the
3 nodes. I also observed that the monitoring of resources is not happening
correctly once the DC changes are observed.
Any help on this issue.
Thanks

Hi Gregg
Can you show me the output of "crm_mon -Afr" ?
And please see pacemaker log.
Pgsql RA may output some reasons why slave cann't be promoted.
Thanks,
Takatoshi MATSUO

Hi Andrew,
thank you for that information. You know, often one answer
is followed by many other questions. The same here:
Is there a tool, where a script is able to determine the
node name based on the uname?
For a script it is easy to find the nodename (uname -n)
it is running on. But what has
What version of libqb is installed?
It doesn't appear to have been installed with yum/rpm.

No. Two nodes are enough. See: no-quorum-policy="ignore".

Hi,
I want to make Postgres cluster.
As far as I understand, for the proper functioning of the cluster must use a
quorum (ie, at least three nodes).
But if the databases are large - it is too expensive.
One master, two slave, and in addition backup.
So I'm trying to make the schema with one master

Hi Andreas,
The metadata section of the document has not been added yet, but we
are aware of it missing and are working to add it. The rest of the
document is accurate though. If you build an agent to follow that API,
it will work with red hat's cluster and pacemaker.
In the meantime, it

I can see that that there is option to define loaction and order
constraints under "crm configure".
But how do I view a particular existing location constraint using crm shell
which I am able to see in crm configure show.

You can also use "crm resource stop p_xxx" here.

Hi guys,
I'm trying to wrap my head around the pacemaker, and setting up postgresql

I used so far following commands to set it up. And this seems to work, but all
nodes are running as slaves (postgresql wise).
The 'master' node (IP address wise) even connects

hi,
what i do this moment:

i.e. ocf:heartbeat:symlink

when i remove the symlink-resource crm_mon tells about an orphaned child on

Still have that with 8807e990c7caec633eaf2480d963365225100d66, so that
doesn't work. Probably "%-*s" should be replaced with "%*s"? "-" is a
left adjustment.
This shouldn't be needed because of:

Thank you for the reply!
What problem you encounter in a production environment?
What repository you added to download stable release 1.0.12 of Pacemaker?
Do you have any conflicts with the dependencies of Pacemaker 1.0.12?
