Do a "df /nfs4exports/home" an "ls -ld /"  a "ls -ld /nfs4exports/home" and a "ls -ld /nfs4exports/" and a "ls -l /nfs4exports".

On the client you can tell which device it is using by what df shows for it, if / it will show the size of / and if correct it will show the sizes of the correct fs.


"df -lhT / /home /nfs4exports /nfs4exports/home" might provide a useful overview.   Directories give entries that match their "parent" filesystem.
box:

For example, a Fedora 32 system shows:

% df -lhT / /home /usr /usr/local
Filesystem                              Type  Size  Used Avail Use% Mounted on
/dev/mapper/fedora_localhost--live-root ext4   34G   18G   15G  55% /
/dev/mapper/fedora_alt-home             ext4  151G   68G   76G  48% /home
/dev/mapper/fedora_localhost--live-root ext4   34G   18G   15G  55% /
/dev/mapper/fedora_alt-local            ext4   69G   27G   39G  42% /usr/local

This shows that "/" and "/usr" reside on the same filesystem ("/"), while "/home" and 
"/usr/local" each reside on a different filesystem.
