    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.

    Regards Johan
