rmtab(4)

NAME

rmtab − local file system mount statistics

DESCRIPTION

File /etc/rmtab contains a record of all clients that mounted remote file systems from this machine. Whenever a remote mount is done, an entry is made in the rmtab file of the machine serving that file system. umount removes the entry of a remotely mounted file system. umount -a broadcasts to all servers that they should remove all entries from rmtab created by the sender of the broadcast message. By placing a umount -a command in /etc/brc, rmtab tables are purged of entries made by a crashed host which, upon rebooting, did not remount the same file systems it had previously. The table is a series of lines of the following form:

hostname:directory

This table only preserves information between crashes, and is read only by mountd when it starts (see mountd(1M)). mountd keeps an in-core table to handle requests from commands such as showmount and shutdown (see showmount(1M) and shutdown(1M)).

WARNINGS

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