Open Stack

I think this fills a gap between “enterprisy” storage backends and DIY backends.
For example, a robust storage platform like NetApp or the like will have features like snapmirror, etc for replication, also I keep hearing that Ceph is getting/very-close to having cross-site replica sets. So that handles cinder with robust backends, but what about those using plain-old LVM?
On the one hand, it sounds like a needed addition, but I’m curious if it’s worth the complication.

I imaging, in a DR scenario, with storage-based replication, a database dump of cinder would be pretty much all that’s required to bring up a new site.

Rather than leaving it up to those of us that may be in a "Vendor Vacuum" or a "Dev Vacuum" I thought it might be worthwhile to get some input.

If there's interest we can either start an ML thread to discuss, or perhaps a meeting to catch everybody up and hash things out a bit.  I'd like to discuss the current proposals and go through what you as Operators may feel should be priorities (or better yet things you don't care about).  I make no promises on the outcome of this little experiment but thought it would be interesting to try and get user input up front before we release new features.
