I’m running software release 2017.10-1 on my Vero 4k and since this update my nfs mount via the fstab stopped working. Even mounting from the command line failed:
root@vero4k:~# mount -t nfs nasty.lan:/share/movies /mnt/movies mount.nfs: an incorrect mount option was specified root@vero4k:~# mount.nfs -s -v nasty.lan:/share/movies /mnt/movies mount.nfs: timeout set for Fri Nov 3 00:04:13 2017 mount.nfs: trying text-based options 'sloppy,vers=4,addr=192.168.1.14,clientaddr=192.168.1.160' mount.nfs: mount(2): Invalid argument mount.nfs: an incorrect mount option was specified
After adding nfsvers=3 to fstab everything works again. My fstab without nfsver=3 worked fine before this update.
