GEOM_MIRROR: Synchronization request failed (error=5).

[Jim Nasby]

Trying to add a disk to an existing gmirror (which, unfortunately is sitting on a GPT partitioned drive):

GEOM_MIRROR: Synchronization request failed (error=5). ad4[WRITE(offset=141343457280, length=131072)]

Does this mean the new drive (ad4) is bad? smartmon doesn’t show anything and a quick bonnie++ test was OK.
