Hi Nejad,

If you want to start an NFS server without rebooting the system, follow these steps.

1) Edit the /etc/exports file and add entries for exported file systems.
2) Use the exportfs -a command to export these file systems.
3) Edit the /etc/rc.config.d/nfsconf file and set proper values to different variables as mentioned
earlier.
4) Execute the /sbin/init.d/nfs.core start command.
5) Execute the /sbin/init.d/nfs.server start command.

The client configuration process
1) Edit the /etc/rc.config.d/nfsconf file to enable an NFS client to be started at boot time.
2) Edit the /etc/fstab file to mount remote file systems at system boot time.
3) Create mount points for the remote file systems.
4) Ensure that the name of the NFS server is present in the /etc/hosts file if NIS or DNS are not
being used.

Jeeshan — Sun, 06 Apr 2008 08:43:23 GMT

you have either problems in

file permission in /etc/exports. it will be 666.

or did u apply command exportfs -a while runnig /sbin/init.d/nfs.server?

run first
#/sbin/init.d/nfs.server start
it will read information listed in /etc/exports

NFS is the solution to share file system from one server to another.

you did exportfs -a /backup, its wrong

you apply command

#exportfs -a

Davis Paul — Sun, 06 Apr 2008 10:39:59 GMT

Hi,
Check the example of /etc/exports file:
/home -access=myhp:hp0
/usr/share/man -ro
/opt/apps -ro
Then execute the command # exportfs -a

>after that i am using exportfs -a /Backup
>exportfs error: invalid argument(s) with -a option

As mentioned by others, with -a, exports all of the filesystems in /etc/exports.

>i try with #exportfs /Backup but another message appeared
>exportfs error: /home not found in /etc/exports

What's the relation between /Backup and /home?

>when edit the /etc/fstab on the client add this
>server:/Backup /Backup vxfs default 0 0

This isn't vxfs but NFS. You may want to use SAM to help you export and to mount it on the client.

>i want to share file between two server, not between server and client

You can't. You can only share the filesystem from a NFS server to NFS clients.
