swapon , swapoff , swapctl - specify devices for paging and swapping
The swapon utility adds the specified swap devices to the system. If the -a option is used, all swap devices in /etc/fstab will be added, unless their ``noauto'' option is also set.
The swapoff utility removes the specified swap devices from the system. If the -a option is used, all swap devices in /etc/fstab will be removed, unless their ``noauto'' option is also set. Note that swapoff will fail and refuse to remove a swap device if there is insufficient VM (memory + remaining swap devices) to run the system. The swapoff utility must move swapped pages out of the device being removed which could lead to high system loads for a period of time, depending on how much data has been swapped out to that device.
The swapctl utility exists primarily for those familiar with other BSD s and may be used to add, remove, or list swap devices. Note that the -a option is used differently in swapctl and indicates that a specific list of devices should be added. The -d option indicates that a specific list should be removed. The -A and -U options to swapctl operate on all swap entries in /etc/fstab which do not have their ``noauto'' option set.
Swap information can be generated using the swapinfo(8) utility, pstat -s or swapctl -l The swapctl utility has the following options for listing swap:
The BLOCKSIZE environment variable is used if not specifically overridden. 512 byte blocks are used by default.
