Removing a Swap File From Use
If you have unneeded swap space, you can remove it.
How to Remove Unneeded Swap Space
- Become superuser.
- Remove the swap space.
# /usr/sbin/swap -d /path/filename
The swap file name is removed so that it is no longer
available for swapping. The file itself is not deleted.
- Edit the /etc/vfstab file and delete the entry for the swap file.
- Recover the disk space so that you can use it for something else.
# rm /path/filename
If the swap space is a file, remove it. Or, if the
swap space is on a separate slice and you are sure you will
not need it again, make a new file system and mount the file
For information on mounting a file system, see Chapter 19, Mounting and Unmounting File Systems (Tasks).
- Verify that the swap file is no longer available.
# swap -l
