'pwd' command not working in a particular directory.

>The /sapmnt/PEP is NFS filesystem which is exported from the same server. The original filesystem is /export/sapmnt/PEP. The pwd command is working fine if you go to the original filesystem.

Can you umount /sapmnt/PEP and then do "ll -d /sapmnt/PEP"?
If you don't have the right permissions on the mount point, bad things happen.

>as a root user the pwd command is working fine in the same directory.

This seems to point to the mount point permissions?

>Is it bug in 11.31?

Sounds like a sysadmin bug. :-)

Only with csh shell this issue is happening.

It is production box not possible to umount:(

We have another 3 nodes with same mount points and permissions. No issue with other nodes.

The scummy C shell uses a different algorithm to find the CWD. It's lazy and just calls /usr/bin/pwd.

In a real shell try these:
pwd
pwd -P
/usr/bin/pwd

> It is production box not possible to umount:(

You might be able to use fire to fight fire.
I.e. if you can export / and mount it on another machine, you can then look at the permissions of /sapmnt/PEP mount point

They should be: dr-xr-xr-x 2 root root

Or even mount it back on itself:
# mkdir ROOT
# mount host1:/ $PWD/ROOT
# ll -d ROOT/sapmnt/PEP
(Then umount when done.)

>We have another 3 nodes with same mount points and permissions. No issue with other nodes.

How do you know without checking? You cloned the machines?

[N,Vipin]

these are cluster nodes.

What is the permission of /sapmnt ? Can you post
ls -ld /sapmnt ?

Thans to you all..
