Lately my drive has been hovering close to failure so I decided to replace it.

Code: 
zpool status -v samsung
  pool: samsung
 state: DEGRADED
status: One or more devices is currently being resilvered.  The pool will
        continue to function in a degraded state.
action: Wait for the resilver to complete.
  scan: resilver in progress since Tue Jun 18 17:24:22 2013
    183G scanned out of 17.6T at 210M/s, 24h12m to go
    18.2G resilvered, 1.02% done

        status: ZFS detected errors on this device.
                The device is missing some data that is recoverable.
           see: http://support.oracle.com/msg/ZFS-8000-QJ for recovery

Ah it feels great to do a seamless replacement.
Thanks ZFS!
 
The failed drive is a Samsung F4EG 2 TB SATA2 5400rpm 32 MB Hard Drive HD204UI

And it got replaced with a:
Model Family: Seagate Barracuda 7200.14 (AF)
Device Model: ST2000DM001-1CH164
