NFS not working anymore after update to 8.4.14

[el-presi]

Hey guys.. sorry for the few details here, but I did not note down the version I updated from in this case

So my issue is:

Since I updated my pve (single node) to 8.4.14, I cannot access any of the (2) NFS shares anymore. Nothing changed in the NFS Server (=Synology NAS), AND: other clients are still able to access NFS shares (including the exact same share, pve should also use (my backup target).

I get the following error:
"mount.nfs: access denied by server while mounting 10.7.0.20:/volume1/Datensicherung"

or:
"TASK ERROR: mount error: mount.nfs: access denied by server while mounting 10.7.0.20:/volume1/photo"

I also restarted both, pve and server and I deleted and recreated the persmissions..

Another Info:

root@pve:~# showmount -e 10.7.0.20
Export list for 10.7.0.20:
/volume1/Datensicherung 10.7.0.19,10.3.0.23,10.3.0.24
/volume1/photo          10.7.0.19

I hope anyone has an idea on this
Thanks in advance!!! BR, Marcel

okay, so after I checked everything from open ports, to logs, to root squash to firewalls and different nfs versions... the isse was, that I had another NIC on the system which now was primary... so I disabled that and now all the stuff is going again over the 10.7.0.19 IP

Glad to hear you got it sorted out! Thanks for sharing the root cause. Having multiple NICs can definitely lead to tricky routing issues. This will surely help others who run into a similar problem.
