Package: src:linux
Version: 5.10.70-1
Severity: important
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Configuring this machine to mount nfs shares
* What exactly did you do (or not do) that was effective (or
ineffective)?
I set up the automounter with the standard mount options of our Arch
clients:
(auto.master)
/misc /etc/auto.misc
-nfsvers=3,proto=udp,resvport,retrans=5,rsize=16384,wsize=16384,rw,hard
When the mount failed, I repeated it manually.
* What was the outcome of this action?
The mount failed:
# mount -t nfs -vvv -o
nfsvers=3,proto=udp,retrans=5,rsize=16384,wsize=16384,rw,hard
<fileserver>:/u/pkgsrc /mnt
mount.nfs: timeout set for Tue Jul 4 18:23:55 2023
mount.nfs: trying text-based options
'nfsvers=3,proto=udp,retrans=5,rsize=16384,wsize=16384,hard,addr=<redacted>'
mount.nfs: prog 100003, trying vers=3, prot=17
mount.nfs: trying 130.83.197.22 prog 100003 vers 3 prot UDP port 2049
mount.nfs: prog 100005, trying vers=3, prot=17
mount.nfs: trying 130.83.197.22 prog 100005 vers 3 prot UDP port 701
mount.nfs: mount(2): Invalid argument
mount.nfs: an incorrect mount option was specified
#
* What outcome did you expect instead?
A successful nfs share mount.
Instead, <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1964093> pointed
me to
# grep "NFS.*UDP" /boot/config-5.10.0-9-amd64
CONFIG_NFS_DISABLE_UDP_SUPPORT=y
#
which disables UDP support for nfsv3 in the kernel.
This upstream decision
<https://www.spinics.net/lists/linux-nfs/msg74889.html> is more than
debatable -- we have been running nfsv3 over UDP for ~20 years here
without ever seeing the data corruption that was claimed as
motivation.
We run nfs through a router (several client subnets accessing servers
in an internal server subnet), and found nfs over udp a lot more
robust in the face or router reboots.
