boldly plowing forwards I request a few disks/vdevs to be mirrored
all at the same time :
bash-3.2# zpool status zfs0
pool: zfs0
state: ONLINE
scrub: resilver completed with 0 errors on Thu Feb 1 04:17:58 2007

needless to say there is some thrashing going on
bash-3.2# zpool status zfs0
pool: zfs0
state: ONLINE
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
scrub: resilver in progress, 0.00% done, 45h14m to go

moments later I see :
bash-3.2# zpool status zfs0
pool: zfs0
state: ONLINE
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
