Unable to cd to a directory

[Poonam_1]

I am unable to cd to a directory.
This directory is mounted on from some other machine.Neither i am able to execute any command on that directory such as ls or even chmod.
If i try to do that then the process just hangs.
When i try to kill these process using kill -9 pid i am not able to kill those process.
What can be the problem and why is the process not getting killed even after using -9 option

Is the other machine up?

If it is, log into it and run exportfs -av

The other machine is up.And i am able to access the other mounted directories but this particular inaccessible directory lies within one of the directory which i am able to access and which is also mounted from the same machine.
I mean directory A is mounted from M1 to M2.
and B,C are a subdir of A.
I am able to access A,C but i am not able to access B.
I executed this command what did u want me to check?

Is B in its own filesystem? Could be a disc crash. Can you cd to B from the host machine?

Can you login to NFS server and try accessing B ? There could be some corruptions ?

i am able to cd to that inaccesible directory from actual machine as well as from any other machine.

Returning to one of my earlier questions, is the directory in its own filesystem? If so, it needs to be explicitly referred to in /etc/exports.

Just try umount and mount again. It may help

I dont understand what is meant by the current file system as well i dont know how do i check that?

[MarkSyder]

1. Login to the server that contains directory B

2. bdf -il|grep (name of directory A).

If directory B is in the same filesystem as directory A you should only see one entry. If directory B is a separate filesystem you will see an entry for it. In this case, you will need to make sure it is in /etc/exports and that the server you want to access it from is listed.
