NFS error when exporting in read only mode.

[Gulam Mohiuddin]

I am getting following error when I tried to export filesystem in read only "ro" mode althogh "rw" mode works:

host:/#exportfs -i -o ro=hosta,hostb /u27/prodfiles
exportfs error: unknown option: ro=hosta

Why "ro" option is not working?

Thanks,

Gulam.

because "ro" does not accept a list of hostnames. You simply use "ro". If you want to export read-only and read-write to a few machines then you would use "rw=mickey,minnie,goofy" and then only hosts mickey,minnie, and goofy would have read-write access; all other hosts would have read-only access.
