The volume doesn't need to be taken down, no, but replication won't
happen by magic either. Basically, for a node to realise that its copy
of the file is no longer current (or that it shouldn't be there, or
should be there, or whatever), the file has to be accessed.
On a webserver or something like that, the access might easily occur
organically (a graphic or html page being served). On file servers
where there's less interactivity, running a simple script that will find
and, say, stat the files in the exported tree (for example) will ensure
