NFS mount in HPUX

[Sreer]

Hello all,

I have a requirement in my production box.


file system /test need to exported from server A must be secured.

only server B must access have rw access to /test

All other servers must have read only access to the exported FS /test from server A.

How can we implement the same?

the entry I put in /etc/exports:

/local/home/INTACT -ro,-root=p650-n33

But while doing exportfs -a Iam getting the below error:

[root@pacfrp2:/]#exportfs -a
exportfs error: only specify one of rw or ro.

Could you pls provide the exact steps?
thanks in advance

Hi,

from 'man exportfs':
The ro and rw options cannot be used on the same exportfs command line.

Use it this way (like mentioned in the man-pages):
rw=hostname[:hostname]...
Export the directory read-mostly. Read-mostly means read-only to most machines, but read-write to those specified.

You just have a small problem in your /etc/exports syntax. Only the first option should start with the minus sign "-", not all of them.

To export the filesystem /test, you should use:

/test -rw=serverB

When you use the rw= option to list the systems allowed to write on the exported filesystem, all the other systems will automatically be read-only. So you don't need the "ro" option in this case. This is called "read-mostly" in the man page.

If you need the root access option, the syntax should be:

/test -rw=serverB,root=serverB

But you *really* should set up your user groups & group permissions so that you won't need the root option.

(the above detailed information is also available on your system, simply use the command "man exports")

Hello All,
Thnaks for your reply.

I have solved the issue by giving only rw to the mentioned server.
Now it seems Ok.

Thanks again
