exporting autofs managed directory using NFS

exporting autofs managed directory using NFS

[ramana]

We are facing problems where /home is managed by autofs ( in Autodir ) 
but this directory is to to be exported using NFS.

Exactly reverse of what autofs supposed to do  -- lol

When tried to mount nfs exported home some where else, Persmission 
denied error is reported by nfs server.

Are you saying you want to reexport an nfs mounted filesystem?  I don't
believe that is supported.

No. Autodir do mount local directories only on autofs mounted fs.

In simple terms, exporting this special case autofs mounted dir using nfs.

I suspect and almost sure that this problem is because of  'The "magic" 
process group'.

Any comments?

The kernel nfs server doesn't export across mountpoints by default.  You
may try using the nohide option, but it has limitations (like the fact
that it must be a single host export).

I suspect that the kernel nfsd may have issues trying to export an
autofs imported fs, so I'd try the userspace nfs server.

What I don't understand is why don't you run an automounter on the other
host and have nis maps that point to the respective home dir locations?
