[Pacemaker] Booth ticket renovation timeout

[Jorge Lopes]

Hi all,

I'm performing a lab test were I have a geo cluster and an arbitrator, in a
configuration for disaster recovery with fail over. There are two main
sites (primary and disaster recovery) and a third site for arbitrator.

I have defined a ticket named "Primary", which will define which is the
primary site and which is the recovery site.
In my first configuration I had in the bothh.conf a value of 60  for the
ticket renewal. After I assigned the ticket to the primary site, when the
renovation time was reached, the ticket was not renewed and it ended up not
assigned to any of the sites.

So, I increased the value to 120 and now the ticket gets correctly renewed.

I am interested to know if there are any kind of constraints for the
minimum value for the ticket renewal. Is there any design aspect that would
recommend higher values? And what about in a production environment, where
time lags might be larger, would such a situation occur? What would be a
typical set of timeout values (please notice the CIB timeout values).

My configurations are as follow.

Thanks in advance,
Jorge
