Removing Swap Space

Sometimes it can be prudent to reduce swap space after installation. For
example, say you downgraded the amount of RAM in your system from 1 GB to
512 MB, but there is 2 GB of swap space still assigned. It might be
advantageous to reduce the amount of swap space to 1 GB, since the larger 2
GB could be wasting disk space.You have three options: remove an entire
LVM2 logical volume used for swap, remove a swap file, or reduce swap space
on an existing LVM2 logical volume.
