The tag volume is ambiguous. It's used at least for:
How should we disambiguate it?
For generic storage topics, there's already storage and block-device. For specific types of volume, there's lvm, device-mapper, etc. So I think we should just get rid of the uses of volume for storage topics, by retagging to existing tags. Eyeballing it, that's maybe 15 questions to retag.
Once we've done that, we should rename volume to something less ambiguous. I propose sound-volume or audio-volume (perhaps both). “sound volume” wins Google Books ngram, for what it's worth.
sound-volume
if only because many users might start typing sound
and so find it.
