Removing disk from zfs pool permanently

Question

I tried to add a SSD to zpool by ZIL but I did a mistake.

I expected.. zpool add zones log c0t1d0
But I did... zpool add zones c0t1d0

I tried to execute zone remove, detach, offline commands, but it failed.
How can I remove a SSD without data loss in zpool?

$ zpool status
pool: zones
state: ONLINE
scan : non requested
config:
   NAME          STATE     READ  WRITE CKSUM
   zones          ONLINE      0      0      0
       c0t0d0     ONLINE      0      0      0
       c0t1d0     ONLINE      0      0      0


$ zpool iostat -v               
capacity     operations    bandwidth
pool        alloc   free   read  write   read  write

UPDATE: the ZoL 0.8.0 release will contain this feature.

@user121391 is correct that today this is not possible except through a send/recv storage migration.

However, there is a new feature developed by Matt Ahrens (head of the OpenZFS community) that is close to landing on the master branch and will eventually make its way to other platforms (FreeBSD / Linux / macOS / etc.). Here is a link to the pull request on Github.

Once it integrates, you will be able to run zpool remove on any top-level vdev, which will migrate its storage to a different device in the pool and add indirect mappings from the old location to the new one. It's not great if the vdev you're removing is already very full of data (because then accesses to any of that data have to go through the indirect mappings), but it is designed to work great for the use case you're talking about (misconfiguration that you noticed very quickly).
