Subject: NFSv4 stability: export unused a night

1/

When I lived yesterday server computer test was up, configured with 1 export
partition.
This export was moutable from the client side.

Threre was no reboot of the server this night.
This morning, I was unable to mount the exported directory.

After reboot, all was OK.



2/
Yesterday, :
Feb 4 17:10:54 roquetav kernel: nfs: server 172.16.109.31 not responding,
still trying

->I was not able to kill and restart the nfsd. All was right after reboot.
Nota this has occured using the python nfs4 test suite.


3/

Using pynfs suite tests.
minors installs bugs fixes.

More precisions. I have reproduced the bug:

1/ Server up, client up
2/ client mount a nfs4 fs.
3/ reboot client (without umounting )
4/ Client can't mount nfs , server answer: permission denied


More... If I kill all nfsd and mountd and reload them, there is still this=
=20
problem. I need to reboot the server

Still answering to my owns questions ;)
I yet have the permissions (I don't really understand what I have changed...
) remounting looks to work (I don't have "permission denied" and the mount
returns without errors), but I can't see thedirectory correctly...

After a reboot and re mounting the partition:
[root@roquetav root]# ls /mnt/nfs/vincent/
[root@roquetav root]#

and without rebooting:
[root@roquetav root]# ls /mnt/nfs/vincent/
