Backup Data Files to SILO

Cron scripts are installed on the idaq account on opsmdaq0 to back up data and delete it from /data and /data1: 

/opt/idaq/cron/cron_opsmdaq0

Do not attempted to copy, delete, move, or rename files. Never !

The scripts assume that data appears in /data*/DIR where DIR = "annihilation" or "compton" or "mott" Files must have the keywords "PEPPo" or "Scalers" or at least "dat". This avoids writing scratch files like root output. Do not start putting data in some new place or with new names. It won't be backed up to MSS if you do that.

The data are deleted from local disks if they have been written in duplicate with correct byte count to the MSS tape silo. The data stay on disk for an amount of time that is related to the amount of disk space is available. If lots of disk available, the data stay forever. If not much disk, the data are deleted aggressively. 

 The data is copied to: /mss/accel/peppo/raw

The copying of data was disabled on January 3rd, 2014.

  • Reference: JLab Module Manuals [1]
  • Mott_SemiInt uses FADC Mode 7 This mode provides:
  1. Pulse integral (sum of all 4ns samples over set threshold, up to 3 pulses per window)
  2. Pulse time (62.5 ps resolution)
  3. Pedestal average of 4 samples at beginning of window.

Issues and FAQ

  • RunNumber: if the run number in msql is different from the one in CODA cool database, coda doesn't work. Open dbedit => localhost => sessions and change the RunNumber to match the one in CODA cool database.
