Package: nfs-common
Version: 1:1.2.6-4
Severity: normal
Dear Maintainer,
I ran into a NFS umount bug, verified and patched in Redhat as per [0].
In my example setup, I have a Wheezy NFS server, using NFSv4 exports, to
a Wheezy client.
When I umount a mount, I receive precisely the same error line on the
server as in [0], e.g.:
Nov 14 09:35:16 saga mountd[3128]: refused unmount request from
cynosure.cora.nwra.com for /data1 (/): not exported
Precisely just as in that case, a RPC packet (NFSv2/v3) is incorrectly sent
from the client to the server.
My export options on the server are e.g.:
/exports/
x.x.x.x(fsid=0,insecure,no_subtree_check,no_root_squash,crossmnt,rw)
[...]
/exports/foo/bar
x.x.x.x(fsid=0,insecure,no_subtree_check,no_root_squash,crossmnt,rw)
My mount options, in /etc/fstab, on the client are:
x.x.x.x.:/foo/bar /mnt/bar nfs4 ro,bg,soft,intr,_netdev,auto 0 2
In [0] (comment 7) there is a proposed patch for RH's nfs-utils.
Debian unstable nfs-common (1:1.2.8-4) lacks the patch, and I'd like to
leave it to professionals to verify whether the small changes of the RH
patch can be used for Debian's nfs-common.
Best regards,
Martin

Hi
[This reply and bug closer is sent for doing BTS maintenance for
src:nfs-utils bugs]
This bug was reported against a very old nfs-utils version without much
followups/triaging itself.
If you can reproduce it with the current version in unstable/testing or
stable at least, please reopen the bug,
https://www.debian.org/Bugs/server-control for details.
Regards,
Salvatore
