Error on mounted remote file systems

[Chui Kock You_1]

Hi R.K,

Permission from L Class.
"backup" already mounted successful, but "back" failed (access denied).

drwxrwxrwx 3 root sys 1024 Sep 15 15:22 back
drwxrwxrwx 7 root root 4096 Oct 1 13:51 backup

How to change the /back permission from sys to root?
Any idea.

Regards
Chui

On the server just use "chgrp root /back".
This shouldn't prevent the mount.

Hi Again..

What error do you get when you try mounting /back on the client.

Please post
#more /etc/exports #(from nfs server)

Hi Dennis & R.K,

Both server hostname AMLICMGE
I want to do remote connect from D Class to L Class by using name /backL1000 -> L Class /back/mdb/db1 (/dev/vg01/lvol12 6144000 1758797 4111198 30% /back/mdb/db1)

Currently D Class already have one remote connection /backupL1000 -> L Class /backup


Result show in D Class:

# showmount -e AMLICMGE
no exported file systems for AMLICMGE

# showmount -e AMLICMGEN02
export list for AMLICMGEN02:
/backup (everyone)

# more /etc/exports

Hi Chui,
According to your words,the nfs "/backup" is ok,and the nfs"/back"is not well.
You need to edit the /etc/exports file in L Class,add the nfs"/back" .
then run the command "exportfs -a" to publish the new nfs"/back".
at last,go to D Class ,mount the remote nfs"/back"

Hi Again,

Yes, you need to edit /etc/exports and add entry of /back. Then run #exportfs -a.

So..
1. Edit /etc/exports in server where /back resides.
2. #exportfs -a
3. NOw, mount it on other server.
