It takes almost 6 hours to run the initial snap mirror sync for this vFiler migration, and its failed twice with

Waiting for SnapMirror-Resync to complete on 'dbdev2, dbdev5, dbdev7' flex-clones…
then
SnapMirror Resync failed: Reason: SnapMirror error: Volume is a clone and scanners have not completed on the parent volume: cannot execute operation 

Src and dest are 3270 clusters running 8.1RC2
This is the last remaining migration blocking our long awaited shelf upgrade - and we have a case open with Netapp 

Anyone seen this one and worked around it?

Thanks,

Fletcher
