When the available volume storage group changes, i.e. the server comes
back up, Coda clients invalidate all cached objects. As a result
whenever any object is accessed the client will refetch the attributes
and version-vectors of all cached objects. When the VVs are different
the client triggers the server-server resolution that will bring both
servers back in sync.

So to quickly force both replicas back you simply run 'ls -lR' in those
replicated volumes that might have missed updates (once the client knows
both replicas are available). Or just ignore the temporary inconsistency
as soon as a client actually accesses any file or directory it should be
brought back in sync automatically.
