I found the reference.

Though these four points were far sundered the Dwarves of different kindreds were in communication, and in the early ages often held assemblies of delegates at Mount Gundabad.

"Early ages" is an ambiguous phrase, but I think the Second Age would still qualify as an early age.

I think Gundabad probably was more the "Mecca" of the dwarves in literally a more religious sense. I don't think it was necessarily a major settlement in terms of population but I think we have to assume some dwarves did indeed live there until its fall.
