Currently there isn't a way to do this without having some additional buffer disk space available. What you can do is attach some vdev to your current raidz. This will create a mirror. After the resync, detach your raidz, do whatever you want to do, like attach the first disk of your raidz. Now you may either detach your buffer-vdev or attach the second disk from your former raidz. The order doesn't really matter that much. And you have moved your pool around without backing up the data. You have to watch the exact sizes of the disks/vdev though, since the space in a mirror only occupies the size of the smallest vdev and grows with the size of the smallest vdev. Last weekend, I had to move a pool around and attached an external USB-drive with a disk considerably larger than my zpool. So I created a zpool on the disk and used a zvol as the buffer-vdev.
