Hi,

The command is used in an NFS server.

showmount -a
============
This shows which and all the clients are mounted the exported file system.This data is taken from /etc/rmtab.

There are some warnings:

If a client crashes, executing showmount on the server will show that the client still has a file system mounted. In other words, the client's entry is not removed /etc/rmtab until the client reboots and executes:
umount -a.

Hi again; forgot to mention -e

showmount -e
============

This command shows what ever the filesystems exported from the server.

The command output will be somthing like
# showmount -e
export list for rx26-217:
/tmp rw=16.118.114.83

Regards,
Sooraj

Hi

From your NFS server -

# showmount -e (* verify that the file system is exported. If not, then "exportfs -av" and re-verify with showmount -e *)

From your NFS client server -

# showmount -a (* verify the the NFS file systme is mounted. If not, them "mount -a" *)
