[Pacemaker] Move Resources
I have configured a cluster with 2 nodes and 2 resources in an active-pasive mode. All is working fine, but i want to set that when a resource fails all resources move to the pasive node. Is this possible?

Re: [Pacemaker] Move resources on failure
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.0/html/Pacemaker_Explained/s-resource-options.html#id649472 Look for migration-threshold. Do not use LSB script for apache, instead carefully study all features of OCF one. On Sun, May 8, 2011 at 8:45 AM, Sergey V.

I would use 'crm migrate resAPACHE' on the active node (for example). You must not forget to finish with 'crm unmigrate resAPACHE' at some point in your examples, otherwise 'resAPACHE' would not return to your formerly active node in any case ;) It is possible I think, but I am not that far yet. BTW: why do you use 'lsb:httpd' instead of 'ocf:heartbeat:apache' ? The pacemaker resource agent is much more reliable in a cluster structure. Killing 'resAPACHE' using the ocf agent produces migration-threshold (infinity) and fail-count (+1) scores which surely can be used to move the resource to another node. I, too, am still learning how that is achieved.

[Pacemaker] Move resources on failure
Hallo! I'm a newbie and I've just set up a small cluster wich consists of two nodes with apache and one mutual ip address. I use corosync and pacemaker. When I kill apache process crm restarts it so that apache continues working, but I want (in case of apache process failure) to make crm move the whole bunch of resources to another node instead. Is it possible? This is my config crm(live)configure# show node centos1 \ attributes standby="off" node centos2 \ attributes standby="off" primitive mutip1 ocf:heartbeat:IPaddr \ params ip="192.168.1.200" cidr_netmask="255.255.255.255" nic="eth0" \ op monitor interval="5s" timeout="20s" primitive website lsb:httpd \ op monitor interval="15" timeout="15" start-delay="15" \ meta target-role="Started" colocation ipapache inf: mutip1 website order apache-after-ip inf: mutip1 website property $id="cib-bootstrap-options" \ dc-version="1.0.11-1554a83db0d3c3e546cfd3aaff6af1184f79ee87" \ cluster-infrastructure="openais" \ expected-quorum-votes="2" \ no-quorum-policy="ignore" \ stonith-enabled="false" --- WBR, Sergey ___ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
