I have tried every thread in here to find out why two servers partially doesn't work with NFS v4.

- I can mount (and browse) the share using command line of the server.
- I have tested the time it takes (based on threads suggesting it is a slow connection), it is 0. seconds each time (less than a second).
- One one proxmox, I have 1 share against same server actually working.
- In GUI, the mount appear to be working. But when clicking "Content", it shows "Result verification failed (400)". However, in the summary page, it correctly show usage information for that share.
- I have a qnap pro NAS and have used it against IPMI-vew and mounts good there.
- There are no firewall between proxmox and NAS (same IP range, not NAT or anything - just local).

I have no clue what is going on. Everything I see, says it is working. I have tried to remove all shares, validate it is totally gone and re-add. Same problem.

This has only occoured in newest version, I have not seen this kind of error before.

I try to avoid reboot the entire proxmox if I can, since I can't do proper backup even withouth the NAS.

Update: I discovered that ProxMox created a share inside the NFS-share and by putting iso-files there, the 400 error was gone for iso-files. And after that, I managed to get it working on one server so far.

Can you look at the nodes syslog during such a "Result verification" problem to see if a more specific error is logged there?

It could be the issue: https://bugzilla.proxmox.com/show_bug.cgi?id=2226 Do you have any dead links or the like in this NFS backing export?
 
I ran into this problem today. It is a symlink issue and my proxmox server are up to date. This fixed it:

Code:
find /mnt/pve/SOMEMOUNT -type l ! -exec test -e {} \; -print
If any results show there, it means there's a broken symlink. Remove it and all will be well.
