How to Remove Extra Swap Space

1. Become superuser.

2. Use the swap -d command to remove swap space.

   # /usr/sbin/swap -d /path/filename

   The swap file name is removed from the list so that it is no longer available for swapping. The file itself is not deleted.

3. Edit the /etc/vfstab file and delete the entry for the swap file.

4. Recover the disk space so that you can use it for something else.

   # rm swap-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 system.

   See Chapter 36, Mounting and Unmounting File Systems (Tasks) for information on mounting a file system.
