[Pacemaker] Clarification about corosync timing values

[Andreas Mock]

Hi all,

the installation guide at 
http://www.clusterlabs.org/wiki/Initial_Configuration#CoroSync
has an example corosync.conf with some values different than 
the defaults described by the man page (corosync 1.2.0).

I would be interested to know why there are different values.

token: 5000   (default 1000)
join: 1000 (default 50)
consensus: 7500 (default >1200)
max_messages: 20 (default 17)

Can someone give insight to this values and there interdependencies?

Thanks in advance
Andreas Mock
