Red Hat Bugzilla – Bug 812510
Need support for a shared 'meta' volume to store 'extra'-glusterd (clustering) information.

Description of problem:
Glusterd doesn't have means of creating a volume exclusively for storing information that may be used in maintaining the cluster outside the scope of glusterd.
This feature is brought in to facilitate clustering solutions like CTDB to be used in conjunction glusterd.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Creating a special kind of automatically created volume seems like a pretty significant change, and since it's only for such a specific purpose I think there needs to be a lot more discussion about requirements and alternatives. How *exactly* would CTDB use this, what characteristics must it have, why can't CTDB use a standard manually created volume, how else might CTDB solve those problems, and what other things might benefit from this feature if it were defined a bit differently?
Currently we are planning to fix the issue by having the proper hooks itself, instead of creating a 'meta' volume.
