The error is about the first device not being in the zpool, so I would 
first make sure that I shell completed the device name (path) instead of 
cut and paste or typing. A hidden character (backspace maybe) could make 
this fail.

If that fails I would try exporting the importing the zpool.

I saw your comment about size, but error is not related to size of the 
new device, but that the zpool command cannot find the existing device 
in the zpool to attach the new one to. You _may_ still have a space 
issue, but that is not this error.
