RAL Tier1 Operations Report for 13th May 2019
Review of Issues during the week 5th May 2019 to the 13th May 2019. |
- We are seeing high outbound packet loss over IPv6. Central networking intend to perform a firmware update to the border routers (provisionally scheduled for Wednesday 22nd May).
- On 7th May, LHCb finished their migration from Castor to Echo.
- We have temporarily halted the setup of Tape for Dune while we bring the new Tape robot online.
- CMS job failures were a result of incorrectly configured jobs trying to access all their data from a Finnish Tier-2.
