Notes from Meeting. |
- The recent problems with Echo were discussed. A summary is also in the Operations report. Several points:
- Current situation is that we have “production” access running
- Atlas and CMS have upper limits on batch jobs about equal to pledge.
- The additional memory for the Dell storage nodes has arrived. This will be added – at least initially in a rolling upgrade. However, it is expected this may take up to something like 2 weeks. (At which point we expect to be able to give full access to Echo). Discussions on the best way to do the memory upgrades is ongoing.
- Before the problem we had noted that the LHCb files came from Castor in a “bursty” way. It was suggested last week that we limit the FTS to smooth out this burstiness.
- When discussing GGUS tickets: LHCb are seeing some file transfer failures between worker nodes and Castor. This to be escalated.
- The requirement for us to be able to easily contact all users of Echo in the event of a problem was noted.
