That won't work L2ARC devices can not be a ZVOL of another pool, they
can't be a file either. An L2ARC device must be a physical device.
I could have sworn I did this with a zvol awhile ago. Maybe that was for
something else...
The check for the L2ARC device being a block device has always been
there.
I just tried a couple of things on one of my test machines, and I think
I know where I was mis-remembering it from: you can add a file or zvol
as a ZIL device.
Frankly, I'm a little confused by this. I would think that you would
have consistent behavior between ZIL and L2ARC devices - either they
both can be a file/zvol, or neither can. Not the current behavior.
