I'm migrating away from Drobo. I have about 4TB of data on a Drobo 5D, which is connected to a Mac Mini and formatted with HFS+. I used this command to copy the data there originally:
sudo rsync -vaE --progress /Volumes/SourceName /Volumes/DestinationName
I'm moving the data to FreeNAS, which uses ZFS. However, this command produced hundreds of thousands of errors when I tried to use it for this move, which I believe may be due to trying to copy extended attributes and resource forks.
What are appropriate arguments to copy data stored on HFS+ to a FreeNAS ZFS dataset? I only want to see a status summary and errors. I'll be running this command from a macOS Sierra Terminal Window.
