Description Jan Kratochvil 2007-07-27 21:13:23 UTC
Description of problem:
After upgrading kernel I can no longer serve NFS shares.

Version-Release number of selected component (if applicable):
kernel-2.6.22.1-33.fc7.x86_64 (the server side)
(client side tested either this one or kernel-2.6.21-1.3228.fc7.x86_64)
nfs-utils-1.0.12-4.fc7.x86_64
nfs-utils-lib-1.0.8-8.fc7.x86_64

How reproducible:
Not tried again.

Steps to Reproduce:
1. /etc/exports: /home   172.20.0.2(rw,no_root_squash,async)
2. service nfs restart
3. export -rav
4. client: mount -tnfs -o rw,hard,nointr,rsize=4096,wsize=4096,suid,dev,async
172.20.0.1:/home /home

Actual results:
server: Jul 27 22:57:05 host0 mountd[22959]: authenticated mount request from
virt:985 for /home (/home)
client: mount: 172.20.0.1:/home failed, reason given by server: Permission denied

Expected results:
Successfully mounted share.

Additional info:
Attached a pcap dump just showing ERR_ACCESS on the packet level.
Simple reboot of the server side back to kernel-2.6.21-1.3228.fc7.x86_64 fixed
the problem.

Could this is a duplicate of bug 249857.  I see this too when I try to mount
file systems from a freshly booted machine running kernel
kernel-2.6.22.1-33.fc7.  But after two hours, it is possible to mount from it. 
I'm in UTC +0200.

I'll shortly upgrade to kernel-2.6.22.1-41.fc7 and see if it solves the problem,
but I thought I'd mention this here right away.

Comment 3 Göran Uddeborg 2007-08-20 18:01:37 UTC
After upgrading to -41 this no longer happens.  It does indeed seem to be the
same problem.
