I've started the process of offloading the last 5 months of raw minute trend data (3.1TB) from h1tw0's SSD raid to h1ldasgw0:/trend-0 spinning media (compressed ZFS file system on SATA-BOY raid). The entire copy-and-verify process takes about 3 days.
Since h1nds0 is not the default NDS for the control room, I'll skip the exporting of these data from their temporary location while the offloading is progressing.
