Data Management & Other Tier1 Service Issues

Site Status Recent changes Planned changes
CERN CASTOR 2.1.11-2 (SL5); SRM 2.10-x (SL4); xrootd: 2.1.11-1
FTS SL4 3.2.1 i.e old
EOS -0.1.0/xrootd-3.0.4
All instances are now on the latest CASTOR version. All of them use the Transfer Manager for internal sceduling (LSF replacement) . The end of August technical stop was used to perform several DB maintenance intervention (security patched on all, including the Name Server, CMS stager DB moved to new more performing hardware, ATLAS stager DB defragmented

Complete the migation to new hardware (all instances -but CMS, and the Name Server)

Resource move (disk space) from CASTOR to EOS is being planned (time scale: October 2011)

Other site news

  • CERN: the CERN-T2 FTS had its agents upgraded to SLC5 (IT SSB post).

CASTOR news

CERN operations and development

The Transfer Manager is now in production on all CERN instances. It shows all the expected advantages compared to the LSF-based scheduling (lightweight and efficient scheduling, less overall complexity). Residual issues are reasonably under control and are worked around satisfactorily.

Resource movement (disk space) from CASTOR to EOS is being planned (time scale: October 2011)
