Hi,

I admit it is on Linux, but still hope to find the answer here...

When Replacing a broken disk I ended up with 2 times the same disk
and thus the zraid is in DEGRADED state:
   pool: zfs-data
  state: DEGRADED
status: One or more devices has experienced an unrecoverable error.  An
         attempt was made to correct the error.  Applications are 
unaffected.
action: Determine if the device needs to be replaced, and clear the errors
         using 'zpool clear' or replace the device with 'zpool replace'.

Any idea how to fix this?
