Description krishnan parthasarathi 2012-04-14 07:34:18 UTC 
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.

Motivation:
This feature is brought in to facilitate clustering solutions like CTDB to be used in conjunction glusterd.

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.
