.SH NAME
|
|
rmtab \- local file system mount statistics
|
|
.SH DESCRIPTION
|
|
.IX "rmtab file" "" "\fLrmtab\fP \(em remote mounted file system table"
|
|
.LP
|
|
.B rmtab
|
|
resides in directory
|
|
.B /etc
|
|
and contains a record of all clients
|
|
that have done remote mounts of file systems
|
|
from this machine. Whenever a remote
|
|
.BR mount (8)
|
|
is done, an entry is made in the
|
|
.B rmtab
|
|
file of the machine serving up that file system.
|
|
.B umount
|
|
removes entries, if of a remotely mounted file system.
|
|
.B umount \-a
|
|
broadcasts to all servers, and informs
|
|
them that they should remove all entries from
|
|
.B rmtab
|
|
created by the sender of the broadcast message.
|
|
By placing a
|
|
.B umount \-a
|
|
command in
|
|
.BR /etc/rc.boot ,
|
|
.B 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
|
|
.IP
|
|
.IB hostname : directory
|
|
.LP
|
|
This table is used only to preserve
|
|
information between crashes, and is read only by
|
|
.BR mountd (8)
|
|
when it starts up.
|
|
.B mountd
|
|
keeps an in-core table,
|
|
which it uses to handle requests from programs like
|
|
.BR showmount (1)
|
|
and
|
|
.BR shutdown (8).

.SH BUGS
|
|
Although the

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