RAL Tier1 Operations Report for 25th February 2019
Review of Issues during the week 18th February 2019 to the 25th February 2019. |
- Castor disk server were physically moved to make room for new procurements. This was done in a rolling manner during Tuesday 19th February. The data on a disk server was unavailable while it was being moved, but relatively little impact on LHCb was observed.
- We have had two Castor disk server crashes since the move gdss776 and gdss783 both lhcbDst disk servers.
- All but one of the ARC CEs has been upgraded. We are observing significantly less load on the machines, which we believe was the cause of most of the other issues observed.
- CPU efficiency is improving. There is an ongoing discussion with CMS regarding some of their jobs. Their most problematic jobs involve large input files (> 10GB) which have metadata spread across the file (this is being worked on by CMS).
