Greyhole question

I setup greyhole and now want to undo what I did. I had a USB drive with 1.1tb of videos and 3 internal drives which were assigned to Greyhole. I then told greyhole that I wanted to duplicate 2 copies of the SMB share on the USB drive, this quickly filled up the internal drives, and reduced the size of the USB drive by about 500gb. I would like to undo this. How can I restore all the files to the USB drive and clean the internal drives, without losing any data?

***BUMP***

Anyone have a solution to this? I searched around but cannot find a way, beyond just copying everything to nicely move everything back to the external USB drive and start again.

Ok thanks!

Any suggestion for the best CLI command to copy and overwrite the data from the greyhole drives back to the USB?

I was going to use cp -avr /media/storage1 /media/usb

Then do the same for storage2

This worked perfectly. Solved.
