What are /zfsfool and /zfsfool1 ?

In any case, you cannot remove a device if there is no data redundancy (mirroring or raidz).

Assuming there is enough space to complete the operation, the only way would be to backup your data, destroy the pool, remove the device, recreate a pool and restore your data.
