We are facing problem related NFS FS..

We were checked the /etc/exports, /etc/xtab, /etc/rmtab & /etc/rc,config.d/nfsconf file entries... we didn`t found any pblm.. NFS service is running properly.. Here i attached the screen shots the above files:--

Re: NFS filesystems are not mounting...( permission denied)
Ensure NFS subsystem is in the kernel
2edit /etc/rc.config.d/nfsconf
3start NFS daemon
/sbin/init.d/nfs.client start
4 /etc/fstab
5 mount the NFS file system.

Re: NFS filesystems are not mounting...( permission denied)
did u checked what i posted before if it is
perfectly ok
next u have to check file permissions also
if u are getting file permission denied error the reason may be the following
u should to check the permissions of the directory you have shared.
The permissions should be atleast 755.

Re: NFS filesystems are not mounting...( permission denied)
Hostname & filesystem config are verified properly...
Now what i am thinking, is this any patches related issue?.. Becaz recently we installed ARPA cumalative patches on this 1 server.. we didn`t done on second..
Thanks in advance,

Re: NFS filesystems are not mounting...( permission denied)
are u logged as root to the NFS client, check the export permissions to determine whether root access to the directory is granted to your NFS client.
If you are logged in as root to the NFS client, and your client is not allowed root access to the exported directory, check the passwd database on the NFS server to determine whether it contains an entry for user nobody. Without root access, the root user on an NFS client is given the access permissions of user nobody. Also, check whether anonymous users are denied access to the directory (with the anon=65535 export option).
If your client is not allowed root access or anonymous user ID access to the exported directory, log in as a non-root user to get access to the directory.
If you are not running NIS or NIS+, or if the server is in a different domain from the client, check the passwd databases on the server and the client to make sure you have a valid login on both machines and that your user ID is the same on both machines. If your user ID is unrecognized on the NFS server, you will be granted the permissions of user nobody.

Re: NFS filesystems are not mounting...( permission denied)
The servers epapp01 & epapp02 are not listed in /etc/xtab on epprddb
fyi:-
epprddb/>>cat /etc/xtab
/export/sapmnt/EP1 -root=epprdci:epprddb:dbEP1:ciEP1,access=dbEP1:ciEP1:epprdci:epprddb
/export/usr/sap/trans -root=epprdci:epprddb:dbEP1:ciEP1,access=dbEP1:ciEP1:epprdci:epprddb
/oracle/EP1/sapbackup -root=ebsdp01:ebsdp02
/oracle/EP1/saparch -root=ebsdp01:ebsdp02
/oracle/EP1/sapreorg -root=ebsdp01:ebsdp02
Please do :-
1)
on epapp01&epapp02
---------
unmount /export/sapmnt/EP1
unmount /export/usr/sap/trans
2)
on epprddb
-------
#exportfs -av
Confirm the server names epapp01&epapp02 in xtab or showmount -e
3)
Then do mount the nfs shares on epapp01&epapp02
Thanks ,
Aneesh
