Dear Experts,

I try to run the Mounted Remote File Systems through SAM in D Class machine (to mount remote file from L Class), but not sure why error appear.

I have check the permission in L Class it seem OK.

D class server configuration
Model:D270
Operating System:HPUX 10.20

L class server configuration
Model:L1000
Operating System:HPUX 11.00

Attached is the screen shot for the error.

can we use command line to try mount the NFS mount point ?

#mount NFS_SERVER_NAME:/ABC /ABC_NFS

Hi

This had been reported as bug JAGae26582. The fix is SAM patch PHCO_36562.

Note that SAM has it's own command set and is different from HP-UX. So it needs to be patched up serparately. If you are not up to date then you're probably missing many SAM patches.

Unfortunately for you, this fix is an 11.11 fix with nothing for 11.00.

Hi Johnson,

Still not able to mount error..
Is the command correct ?

# mount amlicmgen02:/backL1000
mount: amlicmgen02:/backL1000 was either ignored or not found in /etc/fstab

Above error looks like you have not configured NFS mount point share .

Couple things to start from scratch, becoz info post on your original post its very simple and we need to check step by step

1. can ping D Clasd Server <=> L class server

verse vise ?

2. ps -ef |grep nsf

3. # showmount -e servername
current export list on NFS server

# showmount -a
currently connected NFS clients

# mount amlicmgen02:/backL1000 ? -. you are missing ??

mount: amlicmgen02:/backL1000 was either ignored or not found in /etc/fstab

when your trying to mount like above "it will look for the mount point in your "NFS Client"
without specifying were /which directory . System will sreach in "Current fstab file of your nfs client"

Example :-

# mount NFS_SERVER_NAME:/ABC /ABC_NFS_Client

NFS_SERVER_NAME= amlicmgen02
/ABC = Source Directory of your NFS Server
/ABC_NSF_Client = target are were you want to mount

Please take note /ABC_NSF_Client -> directory is temporary mount point for your "NFS Server mount point to have has NFS mount point under your NFS Client

Hi Johnson,

Below is the result show in D Class server.

# ps -ef |grep nsf
root 16024 16010 0 15:01:59 ttyp2 0:00 grep nsf

# showmount -e amlicmgen02
export list for amlicmgen02:
/backup (everyone)

# showmount -a

Hello..

Looks like a typo in previous thread.Correct command is:
# ps -ef |grep nfs

>># showmount -e amlicmgen02
>> export list for amlicmgen02:
>> /backup (everyone)

This means that /backup is exported from nfs server.

All you need is to mount /backup onto the client by using:

# mount :/backup /newdir
Where /newdir is a newly created directory on client (or any other directory that you wish).

R.K. # — Fri, 04 Dec 2009 11:29:33 GMT

If above "mount" command works well (check with #bdf), then to make this mount point permanent on NFS CLIENT, make en entry in fstab:

# vi /etc/fstab
:/backup /newdir nfs soft 0 0

This will survive reboot.

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

>How to change the /back permission from sys to root?

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 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"

Regards
Firmus

R.K. # — Mon, 07 Dec 2009 05:22:37 GMT

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.
