Xrootd server Setup

  • Create a new files system for the xrootd data on weka:  sdfdata/xrd
    • increase SSD cache (set to 100TB)
    • increase HDD object space. The space was increased to a usable 3.8 PB
  • New Xrootd server that exports the S3DF space. server name: sdffermixrd001
    (the server FQN is sdffermixrd001.sdf.slac.stanford.edu . As the sdf.slac.stanford.edu name is not exporter outside the S3DF the IP address, which is routeable, need to be used.
  • Ensure that the S3DF server is accessible from within SLAC: centos7, fermilnx-vNN, lsf batch nodes
  • Connect S3DF xrootd to glast-rdr
  • Connect S3DF xrootd to glast-test-rdr
  • File Archiving

File Migration

  • Migrate data from fermi-xrd012  (server has been shutdown)
  • Restore files from fermi-xrd012 that were not transferred but are on tape to S3DF
  • Migrate data from fermi-xrd011
  • Migrate data from fermi-gpfs

Others

  • Xrootd preload library for RHEL8/9
    • statx is not supported by xrootd
  • ensure fits files can be read with preload lib
  • Move fermi xrootd tools from afs to S3DF

Questions

  • Do the redirector need to be moved of the fermilnx-vNN (02,12, 03,06)
