Re: [Linux-HA] [Pacemaker] Announce: Hawk (HA Web Konsole) 0.2.0
Hi Tim. Thanks for this project, it seems to be exactly what we're looking for. I've installed it (it required spawn-fcgi too on SLES11 64) but I just get a blank page. I've looked at the page source and the divs have style="display: none". Not sure why that's happening, can you think of anything?

The other is if it thinks it can't see any useful information from cibadmin, in which case the expected behaviour would be an error message of some description. Can you please tell me: - What version of Pacemaker you're running - If you run "cibadmin -Ql | grep cluster-infrastructure", do you see any output? If so, what?

Re: [Linux-HA] monitor multiple nodes using single node
Hi, Thanks, i have already gone through this doc. this doc covers that using Pacemaker it is possible to define N+1 Architecture. It does not cover how to implement it. Please share any configuration information or any other doc that defines how to implement N+1 Architecture where one node will take care of N running nodes.

Every node monitors its own resources and they elect one node to co-ordinate the actions of the cluster. This node gets told when any resource fails anywhere. There is nothing to implement, just tell the cluster where they can and cannot run, in your case their "home" machine and the shared backup. ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
Re: [Linux-HA] MySQL RA with replication awareness
Hello again, I haven't finished full port of my script but most of the work is already done: http://hydra.azilian.net/gitweb/?p=linux-ha/.git;a=blob_plain;f=mysql- replica;hb=HEAD I still have some tests to finish and I have one problem with which I would like some help. I implemented the replication awareness within the notify section of the RA where I have all the information about the state of the cluster. However this information is missing in different states of the RA. This is what makes the development a little bit slow :) So my problem is how to find the master_host IP? I need the IP since with replication I want to skip the name resolving. Currently I do that by adding the hostname to /etc/hosts and get it every time I do a demote. Will there be a better way ? I'll continue development and I hope to finish it by the end of the week.

[Linux-HA] resource-agents??
hi , ive got a resource-agent that works 100% on one machine. If i run it through off-test I get the following output: /usr/sbin/ocf-tester -n post1 /usr/lib/ocf/resource.d/heartbeat/postfix; echo $? Beginning tests for /usr/lib/ocf/resource.d/heartbeat/postfix... * Your agent does not support the notify action (optional) * Your agent does not support the demote action (optional) * Your agent does not support the promote action (optional) * Your agent does not support master/slave (optional) 0 when I copy it to another machine and try test it with ocf-test I get the following error, /usr/sbin/ocf-tester -n post1 /usr/lib/ocf/resource.d/heartbeat/postfix; echo $? * rc=1: Validation failed. Did you supply enough options with -o ? Aborting tests why would this be the case? both machines are setup identically running the same versions of heartbeat and pacemaker heartbeat-libs-3.0.1-1.el5 heartbeat-3.0.1-1.el5 pacemaker-libs-1.0.7-2.el5 pacemaker-1.0.7-2.el5 how could I debug this futher ocf-test in more details? as I dont see much in the logs ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
