Mounting Remote file system

[mehul_3]

I want to mount remote file system with /dev/vg01/lvol1 giving following command
mount -F vxfs 10.162.185.7:/dev/vg01/lvol2 /n01 but confronted with following error
mount: /n01: No such file or directory.

Could somebody please hassle free way to resolve the issue.

Hi Mehul,

server 10.162.185.7

/dev/vg01/lvol2 /n01
# cat /etc/exports
check if above filesystem (/n01)is the exports file.

Serverb

mkdir /no1
mount -F nfs 10.162.185.7:/no1 /no1

You need to setup nfs on 10.162.185.7 and export the directory that /dev/vg01/lvol2 is mounted on. also does the directory /n01 exist?

[RUET]

also don't use -F vxfs, this option can only be applied to local mount ..
so use -F nfs, even it's not really needed ..

Don't mount the remote LV volume, but the remote mount point of this LV

Export on the remote side (NFS server) the directory to tour NFS client

On the client, create the directory on which you are going to mount the remote dir ...

mkdir /dir2
mount xx.yy.zz.ww:/dir1 /dir2
cd /dir2
ls

Hi Mehul,

1. check if your nfs is configured.

2. add the entry of the directory you want to mount in the /etc/exports file on the remote server.

3. do exportfs -a

4. mount the file system. also there isn't any need to use the -F option with mount. it works perfectly fine without it.

I could not find exports file getting following error message.
# cat /etc/exports
cat: Cannot open /etc/exports: No such file or directory

[Robert-Jan Goossens_1]

Hi Mehul,

# vi /etc/exports
/n01 -rw -root=[remote_host]
:wq

# /usr/sbin/exportfs -a

On remote_host

# mkdir /n01
# mount -F nfs 10.162.185.7:/n01 /n01

I created a new exports file but could not able to save whatever you have suggested to enter text. One doubt I want to clear that in text you suggest to enter [remote_host].So, should I enter remote hostname as a [srsux004] or simply srsux004.

regards,
Mehul

[Robert-Jan Goossens_1]

srsux004

# vi /etc/exports
n01 -rw -root=srsux004
:wq!
# exportfs -a

[Court Campbell]

I would suggest starting here:

http://www.docs.hp.com/en/5991-1154/index.html

[mehul_3]

I exactly followed a steps by entering new entry suggested in exports file but getting following error message when executed exportfs
exportfs error: unknown option:
rw-root=srsux004

Regards,
Mehul

[Sunny Jaisinghani]

Hi Mehul,

This should work fine.

# vi /etc/exports
n01 -root=srsux004 #root access to srsux004
:wq!
# exportfs -a

Now everthing is working fien but getting error message "permission denied"

Pl, help me in this regard.

Regards,
Mehul

[Robert-Jan Goossens_1]

Please post the exact error message and post the /etc/exports file.

[mehul_3]

when I tried to mount file system using following commnad
mount -F nfs -o rsize=32768,wsize=32768 10.162.185.7:/arch /u01
I got error message "permission denied"
(Note: entry in exports
/u01 rw-root=srsux004)

Regards
Mehul

[Robert-Jan Goossens_1]

(Note: entry in exports
/u01 rw-root=srsux004)

Try this one

/u01 -rw access=srsux004,root=srsux004
exportfs -a

Dear RJ
Still I confronted with same error. I entered the same what you have suggested in export file as following
/u01 rw- access=srsux004,root=srsux004

[cutaway]

you have only one network interface??

try to share to all for test:

vi /etc/exports
/n01 -rw
:wq!

if NFS server is not started, start it on nfs server:

/sbin/init.d/nfs.server start

on clilent, retry to mount using ip addr not the name of the server, for ex:

mount -F nfs 10.10.10.10:/n01 /n01

bye

other question!!:
if you export on nfs server (10.162.185.7) /u01
on the client youmust mount what you share.
You must mount /u01 like this:

mount -F nfs 10.162.185.7:/u01 /u01

[mehul_3]

Thanks for immediate response and I am again troubling all of you and got same error message "Permission denied" while mounting.

Hi Mehul,

Ok, let's take this step by step.

On the NFS server, I want to see the following:

1) bdf - show me exactly which filesystem you're wanting to share
2) cat /etc/exports
3) cat /etc/xtab

Once I know the server is setup correctly then we'll move to the client.

Dave

Thanks Dave

Pl, accept my apologies for not being reply to anyone because I am on leave.

Providing you a more information of what you expected.Pl, refer attached doc

Hi Mehul,

# cat /etc/exports
/arch rw- access=srsux004,root=srsux004

# cat etc/xtab
/n01 -access=rw-root=srsux004
/u01 -access=rw-:access=srsux004,root=srsux004
/arch -access=rw-:access=srsux004,root=srsux004


I think the problem is the syntax you're using to export the filesystems. The "rw- access=..." looks bogus. Also, if you only want /arch exported you should get rid of the other two exported filesystems from the kernel's export table (represented by /etc/xtab).

Here is what I suggest:

1. Unexport everything

# exportfs -uav


2. Modify the /etc/exports entry for /arch

/arch -access=srsux004,root=srsux004


3. Re-export /arch

# exportfs -av


4. Verify that /arch is exported correctly

# cat /etc/xtab
/arch -access=srsux004,root=srsux004


5. Verify that the NFS server resolves the hostname srsux004 to the proper IP address used by the client to send NFS requests. It doesn't matter if you use /etc/hosts, NIS, DNS, LDAP, etc. for hostname resolution, the NFS server needs to resolve the string "srsux004" to the correct IP address in order to grant the mount request and subsequent NFS requests.

Once you've done all this, try mounting the filesystem again from srsux004. If it fails, do a cut/paste of the screen and let me see exactly what it says, including your mount command syntax.

Dave

Shalom Mehul,

My 2 shekel.

showmount -e hostname

If the hostname is the remote host you will see exactly what folders are exported on the remote system. If they exist and there are no permissions blocks in /etc/exports, the mount should be excessive.

Hassle free way to resolve the issue? Little concerning NFS is hassle free.

Dear dave
I did so far exactly what you have suggested but once again failed when I fire cat /etc/xtab and not a single entry found in this file. Following is the snapshot for your referance.

# cat /etc/exports
/arch-access=srsux004,root=srsux004
# cat /etc/xtab
#
