Re: FC Storage integration

["Karel Beneš" <chucky@seznam.cz>]

Hi,
If you’re seeking for reassurance, then lately I was thinking about this too. Why VM-level snapshots on FC storage, when nowadays these storage boxes are smart enough to do LUN-level snapshots. All it would require is proper layout on the storage side. If a LUN (or more LUNs) is dedicated to a VM, then you need to freeze the writes in a VM for a little and call the API of the storage to snapshot the LUN. Removal of a snapshot would be fully transparent. Where it gets more complicated is an app-aware snapshot. And revert to a snapshot, that would have to be done very carefully, nodes should not start panicking that they lost storage. Is this what you meant?

Regards,
Karel
