Hi Allan, >From an earlier post I did a few days ago - response from Andrew

But that won't be set if you don't allow pingd to run anywhere too ;-) Now the bad news, pingd/attrd is busted in 1.0.0 :-( You'll either have to wait for 1.0.1 next week or grab the latest from: http://hg.clusterlabs.org/pacemaker/stable-1.0 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Allan Bailey Sent: Tuesday, 4 November 2008 8:57 AM To: [email protected] Subject: [Linux-HA] how to use pingd for stopping services on a node when/ifit loses network connectivity? I'm running on Ubuntu 8.10, heartbeat 2.1.3, using drbd to replicate the mysql partition. My group of services is drbd, filesystem, mysql, then a shared IP address. In /etc/ha.d/ha.cf I have the IP address of the router/switch for testing for network connectivity. >From the documention on the website I am using the following constraint: <rsc_location id="group_1:connected" rsc="group_1"> <rule id="group_1:connected:rule" score="-INFINITY" boolean_op="or"> <expression id="group_1:connected:expr:undefined" attribute="pingd" operation="not_defined"/> <expression id="group_1:connected:expr:zero" attribute="pingd" operation="lte" value="0"/> </rule> </rsc_location> On the 2ndary server, this seems to work correctly and not bring up the service group when network is lost. On the primary server, it does not shutdown the services. My question: Does anyone have an example of where pingd works for the above? Or a pointer to documentation/examples of how to use constraints correctly? Is the best documentation of constraints, etc., just to read the DTD? thanks, -- Allan _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
