Anyone having problems with NFSv4 in F35?

Yesterday I’ve downloaded a bunch of updates and after today boot I can no longer mount my NAS NFSv4 share. The mount command just sits there forever without throwing any error.

I’ve checked the list of upgraded packages, but nothing seems related, except for the kernel upgrade:

I’ve already tried booting in the older kernel without effect.
If I disable NFSv4 support on my NAS I get the protocol not supported error.
Nothing has changed/been upgraded onto the NAS and I tried to reboot it also.
The only solution I’ve found working is to force the mount command using the vers=3 option.

Now, is anyone else having problems with NFSv4 recently?

So, it seems there’s some problem with Kernel / NFSv4 and at least QNAP NASs:

Are you trying to mount the NAS through /etc/fstab? If so, what does your mount command look like?

I was using “vers=1.0” for the longest, then, at some point months ago that would no longer work. Has to switch t0 “vers=2.0”.

Hope my comments are relevant to your issue(s).

Yes, I mount though fstab, I used to have:
192.168.1.200:/Multimedia /mnt/multimedia nfs4 rw,x-systemd.automount,timeo=14

but I’ve also tried to use
nfs auto

I now switched to nfs auto, vers=3 while waiting for a fix, either Qnap or kernel side.

same problem, fedora 35 and qnap. Work around using “mount -o v3…”. And of course I enabled nfs3 on qnap. Let’s hope the bug will be fixed

If you are using fstab, adding vers=4.0 resolved the issue for me.
QNAP QTS 5.0.0.1932

You will find that in the link provided in the solution, just putting it here to save time.
