Agenda

• Site reports
  • Doris : upgraded to 1.9.1-5 to day.
  • Ron : RT 4316: Error in dumping and restoring srm postgres database. Will be followed up on by Timur. Sara is using dCache version : 1.9.0-6.
  • Triumf : (srm-deployment) : Recently Triumf got couple of time 'timeout failure' on SAM test. There are about 60-70 requests queued in PnfsManager. Gerard reports that as soon as there are requests queued, overall responds times will be higher. A set of improvements are on the way. They are running the 8.3 and 'fast pnfs' which are the recommended versions.
  • PIC : Running 1.9.0-7 : Sometimes SAM tests report 'files not found'. Recommendation : ftp doors should use the permission handler instead of running on the mounted file system.
  • Sara : SRM moved to a separate machine as well as the information service.
  • FERMI : Pool to pool doesn't start when expected. Timur will provide more information on this. (PoolManager > cm ls -r)

• AOCB
