RAL Tier1 Operations Report for 10th December 2018

Review of Issues during the week 4th December to the 10th December 2018.
  • Argo tests for CMS Castor were failing on Monday and Tuesday last week (3rd and 4th December). This was as a result of a BDII problem (it stopped publishing the information).
  • There was a successful load test of the generator on Wednesday,
  • ~5% of SAM tests via GridFTP against Echo have been failing due to the “Address already in use” problem. We are investigating the problem and disabled NIS on the gateways as it is not needed and was using up ~13000 ports. We are monitoring to see if the situation improves.
  • CMS successfully migrated to the new consolidated Castor tape instance on Thursday (6th December).
  • The physical machine hosting MySQL databases for the Tier-1 (RT ticket system + LFC) died on Thursday. The service was restored from backup on Friday on a VM.
