"wouldn't it be very nice to ask zfs to recalculate it's parity and resilver
all the drives to the new state?
Is that posible?"
man zpool
{ snip}
zpool replace [-f] pool old_device [new_device]
Replaces old_device with new_device. This is equivalent
to attaching new_device, waiting for it to resilver, and
then detaching old_device.
The size of new_device must be greater than or equal to
the minimum size of all the devices in a mirror or raidz
configuration.
new_device is required if the pool is not redundant. If
new_device is not specified, it defaults to old_device.
This form of replacement is useful after an existing
disk has failed and has been physically replaced. In
this case, the new disk may have the same /dev/dsk path
as the old device, even though it is actually a dif-
ferent disk. ZFS recognizes this.
-f Forces use of new_device, even if its appears to
be in use. Not all devices can be overridden in
this manner.
