Have a strange issue with mounting an NFS share.

Server: OS Debian 9. /etc/exports:

/var/www    <CLIENT_IP>(rw,sync,fsid=fd095945-8ace-4f31-b349-91bf805ca2ea,no_root_squash,crossmnt,insecure,no_subtree_check)
/mount/test <CLIENT_IP>(rw,sync,no_root_squash,crossmnt,insecure,no_subtree_check)

showmount -e:

/mount/test <CLIENT_IP>
/var/www    <CLIENT_IP>

Client: Ubuntu 14.04 with latest updates, while try to mount any of existing share - getting an error:

mount.nfs: access denied by server while mounting <CLIENT_IP>:/mount/test

The strange (for me) next thing: I can mount share like this:

mount <SERVER_IP>:/ /mnt/nfs

/mnt/nfs now has a subdirectories which exported on a server, but when I try to enter a directory in /mnt/nfs got an error:

bash: cd: mount/: Permission denied

Can anyone advance me?

  • The 'access denied' error message - shouldn't that be SERVER-IP:/mount/test ? Also, are there additional exports on the server you haven't mentioned here? – Haxiel Feb 17 at 9:10
  • I provide a full list of exported filesystems. Yes, seems there a SERVER_IP, i just misspelled. – Николай Шехавцов Feb 17 at 9:16
  • Very strange but I am successfully mount FS on working laptop, seems problem in NFS versions mismatches... I just try to upgrade a test ubuntu client machine and then write here results. – Николай Шехавцов Feb 17 at 9:17
  • You can force the version from the client by specifying the mount option nfsvers=4.0. – Haxiel Feb 17 at 9:26
