Increase the particular Lvol.

# swapinfo -tam
Mb Mb Mb PCT START/ Mb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 18432 0 18432 0% 0 - 1 /dev/vg00/lvol2
reserve - 8643 -8643
total 18432 8643 9789 47% - 0 -

In this case it is lvol2

this is the command

1- you must know what is the logical vol is the swap

2-execute this command

lvextend -L @@M /dev/vg##

@= the new size you need for the swap

## the vg number

Any reason you don't have pseudoswap enabled? swapmem_on(5)
