Most disks think that da10 is not a member of the pool, but da10 thinks that it is. Perhaps you added it as a spare, then physically removed it, and then did a "zpool remove" to remove the spare from the configuration? If you're very very very sure that there is no data on da10 that you care about, you can do "zpool labelclear -f /dev/da10"
