How can I create a new swap location in ZFS?

I am running OpenSolaris v5.11

During installation, the installation created default ZFS filesystems, like the dump and swap locations.

I want to change the blocksize of the /dump and /swap locations and make them ZFS volumes.

The ZFS system is on a zpool called rpool

I was able to do a zfs destroy on /rpool/dump and then create another dump location with the proper options:
zfs create -b 131072 -V 1024m rpool/dump

I cannot destroy /rpool/swap though. It tells me that the ...dataset is busy. I did some investigating and found that I have to do a dumpadm but that doesn't work either:

>dumpadm -d swap
dumpadm: no swap devices could be configured as the dump device

>swap -l
swapfile dev swaplo blocks free
/dev/zvol/dsk/rpool/swap 182,1 8 16775160 16775160

How can I destroy the /rpool/swap directory and then create another swap directory and make it a volume with a particular blocksize? Do I rename the swap location to something else?

Thanx.
