NFS Automount issue in Office

Hi ,

This posts are not for advanced users as they all know these common issues.
I came across this issue regarding NFS automount in my office.
I checked o/p of : df -h but nfs share was not shown in o/p

We though that issue might be from Server end d wanted to check nfs server side , but one thing I didn't know was when we perform AUTO-MOUNTING of NFS share , unless user request for share it is not mounted on specified directory , and that is why client tool was generating message like "share XXX not mounted on XXX"

Finally we suppressed that alarm and now its working fine. :)

Thanks & Regards,
