NAME

rmtab − local file system mount statistics

DESCRIPTION

rmtab resides in directory /etc and contains a record of all clients that have done remote mounts of file systems from this machine.  Whenever a remote mount is done, an entry is made in the rmtab file of the machine serving up that file system.  Umount removes entries, if of a remotely mounted file system.  Umount -a broadcasts to all servers, and informs them that they should remove all entries from rmtab created by the sender of the broadcast message.  By placing a umount -at nfs command in /etc/brc rmtab tables can be purged of entries made by a crashed host, which upon rebooting did not remount the same file systems it had before.  The table is a series of lines of the form

 hostname:directory

This table is used only to preserve information between crashes, and is read only by mountd(1M) when it starts up.  Mountd keeps an in-core table, which it uses to handle requests from programs like showmount(1M) and shutdown(1M).

BUGS

Although the rmtab table is close to the truth, it is not always 100% accurate.
