Thanks David. Maybe I mis-understand how a replace works? When I added disk E, and used 'zpool replace [A] [E]' (still can't remember those drive names), I thought that disk A would still be part of the pool, and read from in order to build the contents of disk E?
Exactly. Disks A and E will be arranged into special vdev of type 'replacing' beneath the raidz vdev which behaves like a mirror. As soon as resilvering is complete, disk A will be removed from this 'replacing' mirror making disk E to stay alone in the raidz vdev.
