NFS mount not working

Hi, I'm trying to make NFS work on Synology DS923+

root:~/ # cat /etc/exports

/volume1/Backup 192.168.2.6(rw,sync,no_wdelay,no_root_squash,insecure_locks,sec=sys,anonuid=1025,anongid=100)

On client I have in /etc/fstab

192.168.2.10:/volume1/Backup /mnt/nfs/nas/Backup nfs _netdev,noauto,x-systemd.automount,vers=4,x-systemd.mount-timeout=10,rsize=8192,wsize=8192,x-systemd.idle-timeout=1min  0   0

and when mounting I see

$ sudo mount -vvv /mnt/nfs/nas/Backup
mount.nfs: timeout set for Sun Nov 19 17:06:37 2023
mount.nfs: trying text-based options 'rsize=8192,wsize=8192,vers=4.2,addr=192.168.2.10,clientaddr=192.168.2.6'
mount.nfs: mount(2): Protocol not supported
mount.nfs: trying text-based options 'rsize=8192,wsize=8192,vers=4,minorversion=1,addr=192.168.2.10,clientaddr=192.168.2.6'
mount.nfs: mount(2): Protocol not supported
mount.nfs: trying text-based options 'rsize=8192,wsize=8192,vers=4,addr=192.168.2.10,clientaddr=192.168.2.6'

Mounts with following works on other computer.

/media 192.168.2.8(rw,sync,crossmnt,no_subtree_check)

Don't know why Synology is preventing the connection

Re: NFS mount not working

Make sure that the Synology actually supports NFSv4, since you're forcing that on the client connection.

Re: NFS mount not working

Beginning with the update to DSM 7.x Synology's NFS only supports protocol "4.0".
Earlier versions of DSM (6.2.x) did support 4.1 and possibly 4.2.
