Re: [Linux-ha-dev] Patch: VirtualDomain - fix probe if config is not on shared storage
I'm not sure my fix is correct. According to https://github.com/ClusterLabs/resource-agents/commit/96ff8e9ad3d4beca7e063beef156f3b838a798e1#heartbeat/VirtualDomain this is a regression which was introduced in April '11. So the fix should be the other way around: Introduce a parameter that let's the user configure the config file _is_ on shared storage and if this is false or unset, return to the old behaviour of returning ERR_INSTALLED.

[Linux-HA] Linux HA for VMs
Has anyone deployed Linux HA for VMs before? A serial cable cannot be set up as heartbeat for VMs, then would using only ethernet network as heartbeating media be a single point of failure? Another certian is if we migrate a VM to another ESX host, the VM will be freeze for a while, will this cause a split brain? Thanks.

Re: [Linux-HA] Web resource monitoring
Hello, The http monitoring code should be split off from the apache RA. Then a simple stateless (see the Dummy RA for a sample) RA, say httpmon, can be created which would source the http monitoring. Patches accepted! Guidance and constructive critique offered :) Ok, thank you for suggestion with name of RA :) Here is what I wrote: https://github.com/dotNox/heartbeat_resources/blob/master/httpmon Small description is available at: http://dotnox.net/2011/06/multiple-ha-resources-based-on-same-service-heartbeat-httpmon-ra/ I did not want to patch or change something in apache RA as if someone will not have any cross of resources, like I have, and it will be easier to use apache RA.

Note that the Heartbeat is not expected to control the httpd service but just to monitor. Say I have Heartbeat, then I have the following configuration questions: 1) Should I use clone for monitoring httpd? No, you should clone the httpd service. Each instance of the clone is responsible for monitoring itself. 2) Which operation should I specified for the action of httpd service? fence or block or another? It depends what you want.
