About dump:  Unless you have r151008 or later, you can only use a zvol on a mirror or single-disk pool.  Having said that:

zfs create -V <size> newpool/dump
dumpadm -d /dev/zvol/newpool/dump

And for swap (which should be good regardless what "newpool" is...):

zfs create -V <size> newpool/swap
swap -a /dev/zvol/newpool/swap
swap -d /dev/zvol/oldpool/swap

Hope this helps,
Dan


Thanks, Dan, that was EXACTLY what I needed!!! And the "newpool", wich is called "mainpool" here, are mirrored disk, yes.
