Do you need to execute crm_ticket on arbitrator?

Hi Jiaju,

Currently, I think that the start-up of arbitrator is normal　to use
/etc/init.d/booth-arbitrator. So I want to remove the execution of
crm_ticket because arbitrator don't has to use cib. What do you think
about it?

Sincerely,
Yuichi

Yes, arbitrator is not using cib. I'm fine with removing the crm_ticket
calling logic on arbitrator. An implementation detail on this issue
would be to keep the modularity of the code structure, that is,
proposer, acceptor and learner is the terminology of paxos algorithm,
site and arbitrator is the GEO clustering terminology, I'd like each
component to be more independent and its internal logic is transparent
to other components.

Thanks,
Jiaju

Hi jiaju,

I understand the answer. Do you fix this problem on the next development?

And, I know that the following function will be developed when you
work the next development.

* new catch-up code
* the refactoring of the transport layer

I would like to know if there are other functions.

Sincerely,
Yuichi

To add more policies and make booth more configurable, add watchdog
daemon.

Also you can raise your feature request if you think something need to
be implemented;)

Thanks,
Jiaju

Currently, I am using RedHat 6.2. And /etc/init.d/booth-arbitrator
dose not work. I ask that I operate an this script on RedHat.

Hi Jiaju,

Would you tell me about these policies in more detail?

Sincerely,
Yuichi

Let's take the renew process as example. In order to keep the original
site holding the ticket, renew process should be started before the
expiring date arrived. Currently we just set this starting point to 80%
of the expiration time. The improvement would be to make the renew
starting point and the renew times to be configurable.

Thanks,
Jiaju
