What do you consider a property? Instance attributes or meta attributes? Or both? I was referring mostly to meta attributes, but having both would be quite useful. Do you have any specific meta attributes in mind? Taking a cursory look doesn't reveal anything very interesting. The defaults for the former live in the RA meta-data and are used only by crmsh (probably some other tools too) to display in brackets when showing the RA info. Note also that the default in the meta-data may not actually match the default used by the RA (it should, but there's no mechanism to make sure). Yes, I understand that. But why would you want to have this? Because otherwise I must somehow find what defaults are and this may change from release to release and from vendor to vendor. I simply want to make sure I have all necessary information that may influence cluster behavior. We try hard to keep the defaults the same between releases, even when they're in retrospective considered to be less than optimal. Otherwise, the existing cluster configurations may fail. But there's no guarantee. It would be possible to implement a small utility which would compare defaults of two RA meta-data. There are also meta-data in crmd, pengine, cib, and stonithd, representing various global cluster properties. As for the resource meta attributes, I'm afraid that one would need to look them up in pacemaker's include files. I was once about to have their descriptions available in a more convenient manner, but got distracted at the time.

[Pacemaker] Linux HA setup for CentOS 6.5
Hi, Is there a tutorial showing how to get a basic Linux HA setup with replicated storage (via DRBD) working on CentOS 6.5? I want to have mySQL as the HA resource with the database replicated across the nodes. I've scoured the web for one but it seems that I get stuck in each one somewhere. To elaborate, I have 2 CentOS 6.5 nodes configured with distinct hostnames and static IPs. They are connected to a wireless AP, and can ping each other. I tried following this guide - http://clusterlabs.org/quickstart-redhat.html However, cman will not start when NetworkManager is running, and my nodes cannot connect to the wireless AP without NetworkManager running. Am I missing something or is that the stupidest dependency ever? How is a cluster supposed to work when the nodes aren't connected to one another? I also tried following the clusters from scratch guide but that seems to rely on systemctl calls which aren't available on CentOS 6.5.

Re: [Pacemaker] Linux HA setup for CentOS 6.5
You can manually configure the wireless LAN without NetworkManager. If you take a look, there should be existing config files in /etc/sysconfig/network-scripts/ for the wireless connection. I've not done it myself since many Fedora's ago, but I believe you can change NMCONTROLLER=no and then start it up with /etc/sysconfig/network start. I could be a bit wrong, but I am sure you can make wireless work without NM. Question; Servers with WLAN?
