This can happen if it gets confused about the version. Can you please collect the result of cat /proc/mounts cat /etc/mtab cat /run/mount/utab just before an unmount which causes the error message to appear on the server? It is probably that the first two are identical as /etc/mtab should be a link to /proc/mounts. Hopefully there will be a clue in there. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What I did first, I run the three commands before and after the error message appears. Then I changed the fstype in the "auto.nfs1701" from nfs4 to nfs and run the same test again. Interesting for me was, that in the second test no error message came up on the server, and the output of utab shows an entry "vers=4" - which is missing when I set the fstype to nfs4. I double checked it: Setting fstype=nfs4 -> utab has no "vers"-entry Setting fstype=nfs -> utab has "vers=4" Hope that helps to narrow it down.

Thanks. So as a work-around you can just use "fstype=nfs". That defaults to NFSv4 and everything works. However there is definitely a bug in mount.nfs as it should report "vers=4" in utab when you mount with "-t nfs4". I'll see if I can find and fix that. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
