Description Frederik Bijlsma 2010-05-28 08:57:08 UTC
Description of problem:

Generally looking into more asynchronous clustering, luci needs ways to handle multi site (asynchronous) clusters. One of the problems is that asynchronous cluster don't need any automatic failover but a most possible coherent config set for the cluster services, with some sets being "local" data and some being "global" data:
- service names etc (global definitions)
- node names (site specific)

see below conversation with pmyers:

> So e.g. the 3rd site node would just get config updates etc, but not
> take part in the synchronous cluster.
Well, config updates are generally site specific (i.e. hostnames of nodes
and of fence devices)  So not sure how useful this would be.

Perhaps luci functionality for defining a cluster and it's mirror, and
making it clearly defined what are site specific config options vs. common
(i.e. nodenames, fencing devices would be site specific.  service
definitions/failover domains could be common)

File an RFE bug against luci in RHEL6 bz on this please.

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.

Comment 5 Lon Hohberger 2011-08-22 20:27:37 UTC
Configuration of clusters in stretch environments is limited to the use cases set forth in the linked Knowledge Base article; as such, the usefulness of this is limited.

Comment 6 RHEL Program Management 2011-08-22 20:45:16 UTC
Development Management has reviewed and declined this request.  You may appeal
this decision by reopening this request.
