If your 3.3 volume is near or over half full, the migration is likely to 
completely fill up your volume and then fail partway through.

I have speculated that if I were to abort the remove-brick before the 
other bricks filled up completely, I could repeat that cycle and 
eventually it would finish with no errors.  I have not actually tested 
this, though.

Thanks,
