gluster/uss: Handle ESTALE in snapview client when NFS server restarted
When NFS server is restarted inode-context is lost. Nameless lookup will be sent to regular volume. If the gfid is from virtual graph, lookup will fail with ESTALE. We need to send a lookup to snapview server Change-Id: I22920614f0d14cb90b53653fce95b6b70023eba6 BUG: 1166197 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/9153 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Sachin Pandit <spandit@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
