By default the get_paths command will make a HEAD request to each path
before it returns them. I don't know how to use the guba client offhand,
but if you pass noverify=1 and you _do_ get paths back, you'll have some
potential weirdness there.
I would advocate running get_paths with noverify=1, then manually trying
to hit the urls it passes back.
If the files aren't there at all you'll have to give us more information
about your setup, or else we'd be shooting in the dark.

I'm using the com.guba java client for mogilefs, and we're using it on
our live site. Twice since we deployed (last week), it seems that
getPaths() has returned an empty list of locations for a file that is
definitely there[1].
Looking through the code for the client and the server I can't see how
this could happen. Has anyone seen this before, or have any ideas on
how I can reproduce it/track it down further?

[1] We get the exception
"com.guba.mogilefs.StorageCommunicationException: unable to retrieve
file with key 'xxxxx' from any storage node: " (there not being any
list of paths at the end means that getPaths() returned an empty array
rather than null.
