The error message is wrong, we don't support the operation on gluster volumes.
I've fixed the error reporting with:
commit 589c2ad93fa0eab8a093037ee95391619f700eb0
Author: Peter Krempa <pkrempa>
Date: Mon Jul 7 16:50:11 2014 +0200
storage: Split out volume upload/download as separate backend function
For non-local storage drivers we can't expect to use the FDStream
backend for up/downloading volumes. Split the code into a separate
backend function so that we can add protocol specific code later.
v1.2.6-120-g589c2ad
And cloned this bug as https://bugzilla.redhat.com/show_bug.cgi?id=1118756 that tracks the feature request to add volume download/upload on gluster.
