NFS mount

[Yajuvendra Singh]

Dear All,

I have HP-UX 11.11 C8000 machine, i have exported a filesystem XYX from server which is been mounted on 'n' no. of machines. This file system has full read/write access.

Problem:
The client machines where the remote file system is mounted XYZ, is not able to read CAD data or store the CAD data in that particular file system, process gets hang.

Please let me know any settings to be done.

Thanks in advance.

Regars,
Yajuvendra Singh

Hi,

Make sure all the users in NFS server and client have same "USER ID". This is important if your NFS user access needs to be consistence across NFS setup. Secondly, roots of NFS client would have minmal access on the FS exported from NFS server. This is default security feature, unless you explicitly include "root" keyword appropiately in the /etc/exports file on NFS server.

The UID of a user in NFS client whose UID is not defined in passwd file of NFS server would be considered as "anonymous" or "nobody" and would be given only minimal access. Please make sure the NFS mounts on the NFS server is indeed exported. Just because NFS server daemons are running doesnot mean that all the FS mentioned in /etc/exports file are exported. You need to explicitly run the command "exportfs -a" on NFS server when u do modifications to /etc/exports file.

Make sure the rpcbind process is running on the nfs server and has not hung.

Once exported from the NFS server, u can use the follwoing commads to verify.

showmount -e , on nfs server will indicate all the FS that are exported.

showmount -a , on nfs server will show you what are the client which are currently mounted the exported FS.

Please also see the man pages of "exportfs" and "showmount" for more info. I have presented a few basic checks above. As such the trouble shooting of NFS is very extensive and should be done systematically to arrive at a solution.
