Pipeline

  • Oracle Upgrade/Tuning/Stress testing done

h3, Low priority items

  • Add prioritization of processes within pipeline
  • Improve performance of web front-end
  • Improve robustness of monitoring (ping can say OK even when server is stuck)

xrootd

  • All new file servers (except wain021) now in production
  • New version of xroot server/redirector/client ready to go
    • Will support read/write access restrictions
      • Write access will be restricted to glast/glastraw/glastmc accounts
      • Read access will be restricted to users listed (with SLAC username) in glast.stanford.edu database
    • Fixes a number of problem with xrootd found over last few months
      • In particular duplication of files when disks become (almost full)
  • Plan to submit CCB request to put this into production (yesterday)
    • Aim to have it in production by early next week.

(Note this will restrict access to data in xrootd to glast users. Most of our NFS disks remain accessible via anonymous FTP. If we care we need someone to look into how to fix this)

Low(er) priority items

  • Turn on automatic archiving of data to tape
  • Automatic taring of small files
  • No labels
