Is there a way to define an alias for a NFS-exported directory directly inside /etc/exports (without using a symlink)?
For example, I want to access this export
/home/username/nfsdir 192.168.0.100(rw,sync,no_root_squash)
as `"hostname:/myalias" instead of "hostname:/home/username/nfsdir".

3Right, but that is the same as creating a symlink. I'm searching for a way to do this using the
/etc/exportsfile only. Something like the share names in Windows/Samba, which are mapped to real paths. – AndiDog – 2010-02-08T11:56:19.250Which OS is your nfs server running? It appears that some nfs servers support a "refer" option which may do what you want. See "man exports" on your nfs server to see if it supports "refer". – Convict – 2010-02-08T12:45:34.483
It's a minimal Debian lenny. Thanks for the suggestion, I'll try that asap. – AndiDog – 2010-02-08T13:13:06.477
Tried
/myalias 192.168.139.0/24(rw,sync,no_root_squash,refer=/real/directory@192.168.39.129)(.129 being the NFS server itself) with no success. It keeps showing me the empty directory/myaliasinstead of "forwarding" me to the files in/real/path. Can you give me a working example config? (note: I tried it with and withoutmount --bind /real/directory /real/directoryas described in the man page) – AndiDog – 2010-02-08T15:22:19.770Sorry, I haven't used the refer option before. :-( I saw it there and thought it might be useful to you. – Convict – 2010-02-09T01:31:23.047
I have a feeling that you can't do what you want from within /etc/exports. However, I can see how to achieve the result you're looking for using NFSv4 and mount -t bind. If you're interested, I can show you my NFSv4 configuration. – Convict – 2010-02-09T10:04:11.180
@Convict Yes, append it into your answer – Eugen Konkov – 2017-01-07T23:29:48.587
