NFS client unmounts. But NFS server still shows mounted
On a Red Hat ES3 client (hostname genesis) I mounted a directory on another server (hostname hnsnas_hpsim ip 192.168.23.108) using the following command
genesis $ mount -t nfs 192.168.23.108:/users1/oraclerman /rmanshare
Later on I unmount the directory using the following command
genesis $ umount /rmanshare
Using the df command /rmanshare is not shown not to be mounted.
But running showmount on the server still shows that genesis is still mounted
[12:11:49 root@hnsnas_hpsim ~]# showmount
Hosts on hnsnas_hpsim:
genesis
Is the client genesis still mounted on hnsnas_hpsim ?

Re: NFS client unmounts. But NFS server still shows mounted
"The completeness and accuracy of the information that showmount displays varies according to the NFS serverâ s implementation."
So the showmount command might be inaccurate.
What's the OS version of the server host, and is it up to date with patches?

Re: NFS client unmounts. But NFS server still shows mounted
There may be an open file handle that may not be triggering the normal "device busy" notice at umount time.
Use fuser to find file handles.
See about the system patches as well.

Re: NFS client unmounts. But NFS server still shows mounted
I tried the export command you suggested. Still the same results :(
