NFS4 pseudo filesystem and home directories

oweinmann — Thu, 05 Jun 2025 06:34:40 GMT

Dear All,

I'm trying to setup an nfs4 autofs (auto.home) mount. Currently all of our linux machines are using nfs3 and some will still be using nfs3 since they don't support nfs4.

Somehow I just can't get home directories to automount via nfs4. I believe it has something todo with the new nfs4 pseudo filesystem. If I understood correctly from the docs nfs4 pseudo filesystem will not allow you to mount subdirectories below an exported top level directory if the sub directory is not explicitely exported too?

e.g.

on the filer I have the following:

/vol/Home/user1

/vol/Home/user2

etc...

my auto.home:

-fstype=nfs4

gedasan02:/vol/Home/&

If I remove the nfs4 it works. I hope I don't have to explicitely export every subdirectory?

Hi,

Since you have not gotten an answer, you may want to ask this question in the NetApp Support Community. The current customers, partners and internal Subject Matter Experts are addressing technical product questions there.

Hi,

I have already raised a ticket for this. On our old FAS 3020c this works fine with nfs4 but on the new filer 2040c DataOntap 8.x it doesn't work. Let's see what they come up with.
