I do not really understand the problem (yet) here are some
questions:
- NFS server is Linux-VServer patched? (yes, no)
if so then:
+ NFS server has NFS tagging enabled? (yes, no)
+ filesystem exported is tagged? (yes, no)
if so then:
* what tagging and what filesystem is used?
- NFS client is Linux-VServer patched? (yes, no)
+ if so then NFS client has NFS tagging enabled? (yes, no)
thanks in advance,
Herbert
