NAME

rmtab − remotely mounted file system table

SYNOPSIS

/etc/rmtab

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(1M) is done, an entry is made in the rmtab file of the machine serving up that file system.  Umount(1M) removes entries, if of a remotely mounted file system. The −a option of umount broadcasts to all servers, and informs them that they should remove all entries from rmtab created by the sender of the broadcast message.  /etc/rc.nfs executes umount −a so that 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).
