[Pacemaker] [ANNOUNCE] The Booth Cluster Ticket Manager - part of multi-site support in pacemaker

[Jiaju Zhang]

Hello everyone,

I'm happy to announce to the Booth cluster ticket manager, which is part
of the key feature for pacemaker in 2011 - improving support for
multi-site clusters.

Multi-site clusters can be considered as “overlay” clusters where each
cluster site corresponds to a cluster node in a traditional cluster. The
overlay cluster is managed by the booth mechanism. It guarantees that
the cluster resources will be highly available across different cluster
sites takes. This is achieved by using so-called tickets that are
treated as failover domain between cluster sites, in case a site should
be down.

Booth is designed to be an add-on of pacemaker, and now it is also
hosted in ClusterLabs, together with pacemaker. You can find it from:

https://github.com/ClusterLabs/booth

Now, booth is still in heavy development, so it may not work for you for
the time being;) But I'll be working on it ...

Review and comments are highly appreciated!

Thanks,
Jiaju
