SWAPON(8) System Manager's Manual SWAPON(8)
NAME
swapon - specify additional device for paging and swapping
SYNOPSIS
swapon -a
swapon name ...
DESCRIPTION
Swapon is used to specify additional devices on which paging and swapping 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 therefore not possible to make use of devices which may be dismounted dur-
ing system operation.
swapon is not implemented in 2.11BSD.
