If you know there is no trouble with the disks, as is the case here (most
probably) then just reenable the disks starting with the one that is not
"Last Erred" since thet "Last Erred" on eis most up to date...
i.e.
metareplace -e d34 c0t0d0s7
and when thats synced up
metareplace -e d34 c0t8d0s7
all done
