.Os
|
||||
.Sh NAME
|
||||
.Nm growfs
|
||||
.Nd start up script to grow the root file-system.
|
||||
.Sh DESCRIPTION
|
||||
The following options in
|
||||
.Pa /etc/rc.conf
|
||||
control the behavior of
|
||||
.Nm :
|
||||
.Bl -tag -width ".Va growfs_enable" -offset indent
|
||||
.It Va growfs_enable
|
||||
.Pq Dq Li NO
|
||||
If set to
|
||||
.Dq Li YES ,
|
||||
the first time the machine boots, the root file-system will be automatically
|
||||
expanded, if possible, to fill up all available space after it.
|
||||
.El
|
||||
.Pp
|
||||
To expand the root file-system with-out rebooting, run the following command:
|
||||
.Dl % /etc/rc.d/growfs onestart
|
||||
.Sh IMPLEMENTATION NOTES
|
||||
The script requires that
|
||||
.Pa awk
|
||||
be present and on the path.
|
||||
This usually means that
|
||||
.Pa /usr
|
||||
should be mounted prior to running the script.
|
||||
.Sh FILES
|
||||
.Pa /etc/rc.conf
|
||||
.Sh EXIT STATUS
|
||||
.Ex -std
|
||||
