Jonathan, Dave:
The file copy completed yesterday. Today we reconfigured nds0 to serve the past 6 months of raw minute trends from its new permanent location. I restarted nds0 daqd at 13:23 PST when H1 was out of lock.
The deletion of the files from tw0's SSD-RAID took from 14:18 to 16:28 (2hr 10min). Final cleanup was to delete the temporary directories under /rawtrends/minute_raw_deleteme on tw0.
