cannot remove gpt/tankssdzil0: operation not supported on this type of pool
According to man zpool:
zpool remove pool device ...
Removes the specified device from the pool. This command
currently only supports removing hot spares, cache, and log devices. A
mirrored log device can be removed by specifying the top-level mirror
for the log.
So zpool remove tank mirror-1 should work. In fact in works fine on
other box with similar configuration.
