WP8376 h1tw1 raw minute trend disk almost full

Jonathan, Dave:

The workpermit was to investigate if we could temporarily use h1tw3's data for h1fw1 instead of  the almost full h1tw1 data disk. We will be decommissioning h1tw1 in October and so we didn't want to go through with a full offload procedure if it could be skipped).

We tested this out initially on h1nds0 (only used by guardian) and found that the NDS1 code could not handle duplicate data (data in both the online raw_minute area and in the archived area).

So we are going to have to do a standard SSD->HDD offload.

h1nds0 was restarted twice (going into test mode, and then reverting back)

h1nds1 was restarted once (getting 5 months of raw minute from the frozen area on h1tw1's SSD while the data is being transferred).

I started the data transfer at 12:53 PDT, it normally takes about a day. h1tw1 disk is 96% full and I expect it to fill by the weekend.
