NFS Share issue

[shikhar_1]

Hi All,

I have exported one FS from server itshrs01. Entries are as follows:

#-> cat dfstab | grep -w "/sap/install"
share -F nfs -o  root=itshrd01.jnj.com:JJCPRD02.na.jnj.com,rw=itshrd01.jnj.com:JJCPRD02.na.jnj.com /sap/install
[root@itshrs01:/etc/dfs]#

[root@itshrs01:/etc/dfs]#
#->  showmount -e | grep -i /sap/install
/sap/install       itshrd01.jnj.com,JJCPRD02.na.jnj.com

Issue is that when i am logged into itshrd01.jnj.com and try to write anything on FS /sap/install, it is giving below errors:

[root@itshrd01:/sap/install]#
#-> touch tt
touch: tt cannot create
[root@itshrd01:/sap/install]#

Although i am able to write on server JJCPRD02.na.jnj.com

Please reply

Sounds like a hostname resolution problem for itshrd01.jnj.com.  Does nslookup on both systems return the same IP address for this host?  Does this NFS client have multiple network interfaces?  Have you verified that the client is using the expected IP interface to access the server and that interface-specific IP address is what gets resolved on the NFS server when you lookup itshrd01?
