Bruce Fields" Cc: linux-nfs@vger.kernel.org Content-Type: text/plain; charset="UTF-8" Precedence: bulk List-ID: X-Mailing-List: linux-nfs@vger.kernel.org Thanks for the insight. That looks to be the case. With debugging turned on the following log entry appears on the re-exporting server: "Cannot export /files/disk2, possibly unsupported filesystem or fsid= required". Understood that there are no plans for a fix in the near future, just wanted to put it on the radar. Will figure out a workaround in the meantime.
