Mount NFS directory as read-only except for 1 sub-directory

[erwindv]

Hi guys,

We currently have a NFS shared Directory mounted as read-only on our server. This directory contains multiple sub-directories and files. It being read-only is a requirement.

Now, we need a directory underneath to be read-write. Is there a graceful way to make that happen? Like a special mount option to use?

Basically objective is:

/u01 is mounted as read-only and has 3 directories: dir1, dir2, dir3
dir3 has 2 sub-directories - sub1,sub2

/u01/dir3/sub2 needs to be read-write, while all other are read-only. Whats the best, most graceful way to do this?

welcome to the forum

have you tried using /etc/exports on the server

/u01 workstation (r)
/u01/dir3/sub2 workstation (rw)

then mounting as usual on the workstation?

Hi. The above solution does not work - /u01/dir3/sub2 is still read-only.

As a workaround, you can mount /u01/dir3/sub2 as read-write using /u01/dir3/sub2as the mount-point (after mounting /u01), but this is still a "two mount" solution, something were avoiding.

P.S. the workaround worked from an OS propective, but Oracle Apps still cant write to it.
