Hi Bob,

Sorry for the delay--are you still experiencing this problem?

I tried to reproduce this in my environment, but didn't see the above 
errors.  Errno 2 is ENOENT, meaning part of the pathname in the mkdir() 
call doesn't exist.  I suspect something went wrong before this, and this 
is just a symptom.  Do you recall any errors creating the export domain? 
Does it look properly mounted on the host and contain the images directory 
from the above log snippet?

I'd suggest re-creating the export domain, if that's feasible, and 
re-trying.  If that doesn't work, please send logs with the re-creation 
and export failure and we'll dig a bit deeper.
