[OpenAFS] Is it in the cache?

Thanks for the tip.  This will probably suffice.

try this:

 $ fs getfid $FILENAME
 File $FILENAME ($xxxxxxxx.$yy.$zzzz) contained in volume $xxxxxxxxx
 $ cmdebug -servers localhost -long | grep $xxxxxxxxx.$yy.$zzzz

This tells you, if a file is "in any way" in the cache. It will however
not tell you, which parts (chunks) of it are stored locally.

Frank
