first make sure nfs daemons are running: ps -ef |grep nfs, if they are not running go to /etc/rc.config.d and vi the nfsconf file...change the NFS_CLIENT to 1 vs. 0 and NFS_SERVER respectively.
then start nfs from /sbin/init.d/nfs*
once daemons are running...
then create your /etc/exports file, see manpage for exports for more info on this file.
make sure the /etc/exports file includes your /home/firstuser entry...save it, then run exportfs -a on server A
then on server B mount -F nfs serverA:/home/firstuser /tmp_mnt
make sure that /tmp_mnt (or whatever you want to call your mountpoint on serverB) has been created (with mkdir).
Hope this helps.

Into server A /etc/exports contains:
serverA:/->cd etc
serverA:/etc->cat exports
/sap/P1/exe -anon=65534
/sap/P1/global -anon=65534
/sap/P1/profile -anon=65534
/usr/sapp/trans -anon=65534
/usr/sapp/P1 -anon=65534

now, it has the following message:
serverB:/->mount -F nfs serverA:/usr/sapp/P1 /usr/sapp/P1
mount: access denied for serverA:/usr/sapp/P1

Into server B already is created the folder named /usr/sapp/P1

why do not works at the moment when i want to mount de nfs?

Thanks ...

Hi,
Just curious to know whether did you restart your NFS deamon after new configuration. If so, restart it.

Hi,

Your machine name is not in the export list for the file system you are trying to mount from the server.

There can be any typo; so Execute this command

#showmount -e hostname

Hi,
Please export the filesystem again:-) using following commnands;

1. Editing the /etc/exports file appropiately
2. re-exporting the exports file with the /usr/sbin/exportfs -a command.

Then try again:-).

Re: NFS

Manuales — Mon, 04 Dec 2006 00:39:29 GMT

serverA:/usr/sap->showmount
serverB

serverB:/sbin/init.d->showmount

hi manuales,

It seems like the portmapper doesn't want to talk to you, or something is broken.

I would suggest that you Kill nfsd, mountd, and the portmapper and try the sequence again.

hope this helps!

kind regards

Hello,
The problem looks like rpcbind problem, so please restart nfs daemon on both the server and client.

Re: NFS

Manuales — Mon, 04 Dec 2006 00:52:16 GMT

ok .. appeared:

serverB:/usr/sap/CP1->mount -F nfs serverA:/usr/sap/CP1 /usr/sap/CP1
mount: serverA:/usr/sap/CP1 on /usr/sap/CP1 : Device busy

/usr/sap/CP1:
serverA:/usr/sap/CP1->bdf | grep usr
/dev/vg00/lvol7 997333 273593 624006 30% /usr

serverB:/usr/sbin->bdf | grep usr
/dev/vg00/lvol7 401408 292590 102024 74% /usr
serverC:/usr/sap/trans/
1024000 279431 698115 29% /usr/sap/trans
/dev/vgsap/sapcp1 5128192 620850 4225646 13% /usr/sap/CP1

I think what is the problem ... is the size???
serverA's size is greather than serverB's , is not it?

mmmm...
taking advantage of your help ..

how do i do a link??
how do i use ln command??

for doing something like this one (where appears "->" ):
lrwxrwxrwx 1 root sys 18 Nov 24 2001 global -> /sapmnt/CP1/global
lrwxrwxrwx 1 root sys 19 Nov 24 2001 profile -> /sapmnt/CP1/profile

THANKS ...

Senthil Prabu.S_1 — Mon, 04 Dec 2006 01:10:14 GMT

Links are of two types.
Soft anf hard....

ln -s sourcefile destination file
creates only a soft link.

This is what you want I guess.

Read this page for clear understaning....

Hi,
Space is not a problem. On serverB, I guess you are in the dir usr/sap/CP1 and running the mount command. so come out of dir usr/sap/CP1 and execute the mount command.

#cd ..
So, ur currnet dir will be usr/sap/
then execute mount command
