I installed nfs-utils and its deps extensions. My goal is to mount a directory on an remote NFS server (an embedded system with busybox).
Here is the error I got:
tc@xxx:~$ sudo mount <nfs-server-ip>:/root/test ./mnt/
mount.nfs: an incorrect mount option was specified
mount: mounting <nfs-server-ip>:/root/test on ./mnt/ failed: Connection refused
On the remote server, I got this line in /var/log/messages:
Oct 27 18:45:15 daemon.notice mountd: authenticated mount request from <tc-ip-address>:981 for /root/test (/root/test)
Nothing unusual there!
When I googled around, I found someone mentioned that using -o nfsvers=3 might solve this problem. However this is not an option in the nfs command extension.
Any ideas how to work around this?
