[Pacemaker] Enabling debugging with cman, corosync, pacemaker at runtime

[Andreas Mock]

Hi Michael, hi all others,

 

I've to admit that I was to stupid to interpret (yes yes, there

is a distinction between reading and understanding) the man page

correctly. So, for the protocol, what I've done.

 

* edit cluster.conf, insert or change entries. Update

attribute config_version="XX" by one.

* distribute cluster.conf via rsync or whatever to all nodes

when not using ricci

* issuing a cman_tool -r -S version

 

That's it. A big thank you to Michael.

 

Best regards

Andreas

Hi Michael,

 

this doesn't seem to have the desired effect.

 

Please enlight me how to change the cluster.conf and

telling all participants to react on that change.

 

Best regards

Andreas Mock

cman_tool -r -S

 

For the details see man cman_tool.
