[Lukasz]

Ohh… I forgot mention:
it's 12.1-p3

# zpool status -v mypool
    pool: mypool
   state: DEGRADED
 status: One or more devices has experienced an error resulting in data
          corruption.  Applications may be affected.
 action: Restore the file in question if possible.  Otherwise restore the
          entire pool from backup.

Yes, I did exacly as you wrote - removed the failed drive, installed a replacement drive, and issued a 'zpool replace' command.
I tried this way to:
I disabled running services in that pool, unmounted and mounted it again. Even I exported/imported that pool.
It has no readonly property.
Of course I have a backup.
