NAME
       swapon - specify additional device for paging and swapping

SYNOPSIS
       /etc/swapon -a
       /etc/swapon name ...

DESCRIPTION
       Swapon  is used to specify additional devices on which paging and swap‐
       ping are to take place.  The system begins by swapping  and  paging  on
       only  a  single  device  so that only one disk is required at bootstrap
       time.  Calls to swapon normally occur in the system multi-user initial‐
       ization  file  /etc/rc  making  all swap devices available, so that the
       paging and swapping activity is interleaved across several devices.

       Normally, the -a argument is  given,  causing  all  devices  marked  as
       ‘‘sw’’ swap devices in /etc/fstab to be made available.

       The  second  form gives individual block devices as given in the system
       swap configuration table.  The call makes only this space available  to
       the system for swap allocation.

SEE ALSO
       swapon(2), init(8)

FILES
       /dev/[ru][pk]?b     normal paging devices

BUGS
       There  is no way to stop paging and swapping on a device.  It is there‐
       fore not possible to make use of devices which may be dismounted during
       system operation.
