Hi,

I must export fs by NFS /opt/dir1/fich1
but in /etc/exports already is exported /opt/dir1.

Is possible a /etc/exports with this:
/opt/dir1
/opt/dir1/fich1
How can i do it??

Thanks and regards.-

It's possible, but unnecessary: when you run it it will tell you that the parent directory is already exported. Because you've exported the parent, fich1 is already available.

It's not possible to export a subdirectory of an already exported directory.
You could export /opt/dir1 to include the host you want to mount on and only mount /opt/dir1/fich1.
Or unexport /opt/dir1 (exportfs -uv /opt/dir1) and then export /opt/dir1/fich1. Of course any hosts that had /opt/dir1 mounted would then lose access.

You don't need to export sub directories with exportfs command.

man exportfs says,

You cannot export a directory that resides within the same file system
and is either a parent or sub-directory of a directory that is
currently exported. For example, /usr and /usr/local cannot both be
exported if they reside in the same disk partition.

Whenever you export a directory through NFS, all sub direcortories will also be exported and available.. So, its not necessary to do so.

thank you,
Could i then mount /opt/dir1/fich1 in server node and mount it in server client without problems?
Thanks and sorry because my questions..

If you've exported the parent directory you should only have to cd on the client.

Yes surely.

Example:

# exportfs -iv /opt/dir1

will not consider /etc/exports file.

# mkdir /tmp/trydir
# mount /opt/dir1/fich1 /tmp/trydir
# ls -l /tmp/trydir /opt/dir1/fich1

will be same.

### Revert procedure ####
# umount /tmp/trydir
# rm -rf /tmp/trydir
(will revert to old stage ;) )

1. Check what /opt/dir1 is exported as

2. log in to node 2 and type:

cd /vol//fich1

where is the result of test 1.
