WP8572 h1tw0 raw minute trend data offload

Dave:

today I completed the h1tw0 offload process which I had started last Friday. Today at 09:55 PDT I restarted h1nds0 (IFO was unlocked) with its new daqdrc configuration serving the past 9 months of minute trends from their final archive location. I was then able to delete the 256,674 old files from h1tw0, taking its SSD raid usage from 94% down to 2% (this took just over 2 hours). h1tw0 is now good for another 9 months.
