Thanks again for putting together such helpful information. This is the way I think people should make tutorials. This is even better than your previous post and that one was very helpful.

I had a question about your mention that the size of the blockchain was currently 417GB in mysql. Do you get that from the amount of space used on /mnt/ or from the size of /_data/ or from a mysql query. My /_data/ directory is currently using 388GB, and I want to make sure that some of the issues I had early on didn't result in missing information.
