Swiss Grid Operations Meeting on 2015-12-10
Site status
CSCS
- Storage
- dCache: stable but still have to run the cleaner manually. Upgrade to 2.10 will be performed on Wed 13th Jan 2016
- Atlas: working on the monthly dumps
- GPFS (scratch): nothing to report
- New hardware: 4 server for dcache and ~1PB of storage. Working to move GPFS metadata disk on Flash based storage.
- Compute
- Added some check function to nodehealtcheck:
- SWAP cleaner
- auto solve some blakhole scenarios like auto remount fs
- after 60 + random number of days the node is putted in dreain for clean and reboot
- Started some test with new slurm version, to migrate sltop.
- Today we will order 40 new compute node with E5-2680v4

UNIBE-LHEP
- Operations
- ATLAS specific operations
- Stable worflows by ATLAS (very large improvement since beginning of run II)
- Stuck with the implementation of monthly dumps of the namespace on the DPM SE:
- headnode on SLC5: the dump script does not work and also generating a valid proxy is problematic
- decided to push the re-deployment of the head node on SLC6
- legacy config tool (YAIM) no longer supported
- puppet based configuration, got the right docs at the DPM workshop earlier this week in CERN
- tests ongoing on a pps VM
- also complicated by the fact my site-bdii is still co-located with the DPM head node
- this will likely be the first task for 2016
UNIBE-ID
UNIGE
- Operations
-
- atlasfs29.unige.ch : New certificate
- Another File Server has been already installed, but this is for DAMPE experiment (no host certificate needed)
- We have new hardware to be installed at the cluster: File Servers and a couple of PCs for services
- We will install puppet for DPM and probably cluster configuration and setup: Let's say we will use a testbed with atlasfs29 + 1 PC of service (1 out of 2, of the previous ones mentioned just above)
- Network - Outlook
- We intend for a new network switch of 10 Gb/s, but this is still under negotiation
- Most likely, it will be in the beggining of next year
- Storage
- There wass a DPM SE workshop at CERN on December 7th-8th: https://indico.cern.ch/event/432642/
- Checking the data stored at the DPM SE for cleaning purposes, since ATLAS requested it
- Checking data in order to identify files which are registered in the catalogue (rucio), but not physically at the DPM SE and vice versa
