[Linux-HA] ocf:heartbeat:anything

2011-06-03 Thread Mateusz Kalisiak 
Hello,

I have succesfully configured a simple two-node cluster. The cluster manages
only two virtual IPs, so far.
I'd like to add another resource, which would be a simple application which
is started by "init.d-type" script, for example: /etc/init.d/app start.
After start it is running "daemon-like".
As I suppose I should use ocf:heartbeat:anything resource agent to manage
this application.
Unfortunately when trying to use it I get some unknown_errors and process
fails to start:

What are the prerequisites to run process by ocf:heartbeat:anything? Should
I use some different agent? Maybe the only way is writing your own agent?
I'll be grateful for any help.

You probably will want to use the -f option with strace.

The Selinux is disabled.
I am launching corosync with command "/usr/etc/init.d/corosync start"

How to "strace" lauch of corosync ? Also, how to check the UID?

Selinux is disabled? 'getenforce' returns permissive/disabled?

How are you launching corosync, init script or direct?

What UID are you launching corosync as?

Does 'strace'-ing the launch of corosync reveal anything?

Maybe this is better way:

Hi!

I moved to IPaddr2 in the meantime. Patching out the iflabel parameter is 
probably bad as it will make a valid configuration invalid. The only proper fix 
is to implement it.
