SWAPON !!!SWAPON NAME SYNOPSIS DESCRIPTION NOTE SEE ALSO FILES HISTORY ---- !!NAME swapon, swapoff - enable/disable devices and files for paging and swapping !!SYNOPSIS __/sbin/swapon [[-h -V] /sbin/swapon -a [[-v] /sbin/swapon [[-v] [[-p__ ''priority''__]__ ''specialfile'' __... /sbin/swapon [[-s] /sbin/swapoff [[-h -V] /sbin/swapoff -a /sbin/swapoff__ ''specialfile'' __...__ !!DESCRIPTION __Swapon__ is used to specify devices on which paging and swapping are to take place. Calls to __swapon__ normally occur in the system multi-user initialization file ''/etc/rc'' making all swap devices available, so that the paging and swapping activity is interleaved across several devices and files. Normally, the first form is used: __-h__ Provide help __-V__ Display version __-s__ Display swap usage summary by device. This option is only available if ''/proc/swaps'' exists (probably not before kernel 2.1.25). __-a__ All devices marked as ``sw'' swap devices in ''/etc/fstab'' are made available. __-p__ ''priority'' Specify priority for __swapon__. This option is only available if __swapon__ was compiled under and is used under a 1.3.2 or later kernel. ''priority'' is a value between 0 and 32767. See swapon(2) for a full description of swap priorities. Add __pri=__''value'' to the option field of ''/etc/fstab'' for use with __swapon -a__. __Swapoff__ disables swapping on the specified devices and files, or on all swap entries in ''/etc/fstab'' when the __-a__ flag is given. !!NOTE You should not use __swapon__ on a file with holes. Swap over NFS may not work. !!SEE ALSO swapon(2), swapoff(2), fstab(5), init(8), mkswap(8), rc(8), mount(8) !!FILES ''/dev/hd??'' standard paging devices'' /dev/sd??'' standard (SCSI) paging devices'' /etc/fstab'' ascii filesystem description table !!HISTORY The __swapon__ command appeared in 4.0BSD. ----
