/dev/hda5 – activate the swap
Swapon is used to specify devices on which paging and swapping are to take place. Calls toswapon 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:
- Provide help
- Display version
- Display swap usage summary by device. Equivalent to “cat /proc/swaps”. Not available before Linux 2.1.25.
- All devices marked as “swap” swap devices in /etc/fstab are made available. Devices that are already running as swap are silently skipped.
- When -a is used with swapon, -e makes swapon silently skip devices that do not exist.
- -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 for a full description of swap priorities. Add pri=value to the option field of/etc/fstab for use with swapon -a.
