NFS mount

[Wael_4]

I have a problem as per the following scenario:
1) created one export NFS folder on one host
2) mounted the NFS exported folder from other two hosts successfully
3) from one of the other hosts which the exported NFS folder mounted I can not process the followin command
touch ww
but from the other host I can

what is the problem that I have
I set the NFS as read-write for both hosts.

please help

Can you check the permissions of Mount Point Directory??

Regards,

[Wael_4]

it's the same for both system but with another user as the following
drwxrwxrwx 13 fq1adm sapsys 1024 Mar 2 14:57 /trans
drwxrwxrwx 13 fd1adm sapsys 1024 Mar 2 14:57 /trans.

Try loggin with that specific user and see if you can touch any file.

when I log with fd1adm on the host afgdev1 and access the mount pont I get
touch: ww cannot create
however in the other system which is afgqas1 when I login with fq1adm
no prblem creating the file

Hey;

Run the following commands on either (or both) of the nfs clients and post the results:

showmount -e ${nfs_server}
mount | grep trans
grep trans /etc/fstab

On the nfs server, run and post:

exportfs

That should help us troubleshoot your issue a little better.

Hey;

You don't have the /usr/sap/trans exported rw to afgdev1. If you specify a rw list, every other client that can mount it will be set read only.

If you re-export the filesystems adding afgdev1 to the rw list, you should be good to go.

BTW, you'd probably get more people willing to help you out if you'd supply some points to the answers that you receive.

Oops; never mind. I xfer'ed your list to a vi session and apparently didn't get the entire /usr/sap/trans thing. Looking at it again, I see the afgdev1 in there.

Next thing to do is to check the uids of the users trying to write as well as the permissions on the exported filesystem:

On failing client:

id ${user}

On working client:

id ${user}

On NFS server:

ls -ld /usr/sap/trans

Post those; maybe we'll see something tere.
