Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-nfs-owner@vger.kernel.org List-ID: So, the problem I reported earlier with failing to unmount was fixed by the back-ported patch. Now, another problem is reported by my user. In this case, they are trying to mount an IPv6 NFS server using NFSv3. Kernel is 3.9.11+, with patches to support binding mount points to local IP (v4/v6) addresses. Some NFS over IPv6 mounts work fine, but some do not. A reboot of the NFS client machine did not fix the problem. I have tried to reproduce the problem locally, but so far everything works fine for us. >From my own app's logs: # mount -t nfs [4001:1::1:1]:/vol/vol1 /mnt/lf/RDnfse11c0 -o srcaddr=4001:1::1:201,vers=3 # requested NFS version or transport protocol is not supported When this problem happens, I do not see any network traffic when trying to mount. I am curious if anyone else has seen errors similar to this? Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
