rmtab(4) File Formats rmtab(4)NAME
rmtab - remote mounted file system table
SYNOPSIS
/etc/rmtab
DESCRIPTION
rmtab contains a table of filesystems that are remotely mounted by NFS clients. This file is maintained by mountd(1M), the mount daemon.
The data in this file should be obtained only from mountd(1M) using the MOUNTPROC_DUMP remote procedure call.
The file contains a line of information for each remotely mounted filesystem. There are a number of lines of the form:
hostname:fsname
The mount daemon adds an entry for any client that successfully executes a mount request and deletes the appropriate entries for an unmount
request.
Lines beginning with a hash (' #') are commented out. These lines are removed from the file by mountd(1M) when it first starts up. Stale
entries may accumulate for clients that crash without sending an unmount request.

rmtab - table of local file systems mounted by remote NFS clients
Description
The file resides in the directory and contains a list of all remote hosts that have mounted local file systems using the NFS protocols.
Whenever a client performs a remote mount, the server machine's mount daemon makes an entry in the server machine's file. The command
instructs the server's mount daemon to remove the entry. The -b command broadcasts to all servers and informs them that they should remove
all entries from created by the sender of the broadcast message. By placing a -b command in tables on NFS servers can be purged of entries
made by a crashed client, who, upon rebooting, did not remount the same file systems that it had before the system crashed. The file is a
series of lines of the form:
hostname:directory
Rather than rewrite the rmtab file on each request, the mount daemon comments out unmounted entries by placing a number sign (#) in the
first character position of the appropriate line. The mount daemon rewrites the entire file, without commented out entries, no more fre-
quently than every 30 minutes. The frequency depends on the occurrence of requests.
This table is used only to preserve information between crashes and is read only by when it starts up. The daemon keeps an in-core table,
which it uses to handle requests from programs like and
Restrictions
Although the table is close to the truth, it may contain erroneous information if NFS client machines fail to execute -a when they reboot.

Hi ,
Is there any way we can find what the resources that are mounted by clients on a server via NFS.
I tried dfmonts but it doesn't show anything. Also /etc/rmtab file doesn't have the information.
