Re: [Pacemaker] booth is the state of "started" on pacemaker before booth write ticket info in cib.
Hi Xia and Jiaju,
Because RA may read an unintended file, I think that it is better to
check the existence of lockfile in RA. I detailed a previous mail.
What do you think about this?
If you agrees to this, Could you fix RA?
Sincerely,
Yuichi

[Pacemaker] When VIP failed, pacemaker stops tomcat resource.
Hello there! I have two nodes with pacemaker. Other resources act as I think, but when VIP failed(shutdown network device by ifdown command), tomcat resource also stopped. Is this normal situation? Tomcat resource is configured by ocf::heartbeat:tomcat. Please give me some help! ___ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org

[Pacemaker] Exchanging data between resource agent instances
Hello, anyone knows if is it possible to exchange data between two instances of a resource agent? I have a Master/Slave resource agent that, when slave, has to create a dummy device in same size of a given block device (DRBD) running on Master. Since the block device is not accessible when the resource is slave, I was wondering if master could read size of device and report it to the slave. I don't like the idea of putting that size in the cib.
