RAL Tier1 Operations Report for 2nd July 2018
Review of Issues during the week 25th June to the 2nd July 2018. |
- Tier-1 are currently undertaking a campaign of better keep a track of our smaller VOs and trying to provide a more proactive approach to monitoring VOs usage (and where required, intervention). Among a number of methods we are using a combination of InfluxDB, Telegraf and Grafana we are now monitoring and alerting on weekly usage of all the smaller VOs.
Current operational status and issues |
- None.
Resolved Castor Disk Server Issues |
- None
Ongoing Castor Disk Server Issues |
- None.
Limits on concurrent batch system jobs. |
- CMS Multicore 550
Notable Changes made since the last meeting. |
- None.
Entries in GOC DB starting since the last report. |
Declared in the GOC DB |
- No downtime scheduled in the GOCDB for next 2 weeks
Advanced warning for other interventions |
The following items are being discussed and are still to be formally scheduled and announced. |
Listing by category:
- Castor:
- Update systems to use SL7 and configured by Quattor/Aquilon. (Tape servers done)
- Move to generic Castor headnodes.
- Networking
- Extend the number of services on the production network with IPv6 dual stack. (Done for Perfsonar, FTS3, all squids and the CVMFS Stratum-1 servers).
- Internal
- DNS servers will be rolled out within the Tier1 network.
- Infrastructure
- There is currently a scheduled three day period (July 24th - July 26th), where RAL Tier-1 will be undertaking server room circuit breaker testing. Although it is believed that these tests should not effect our services, such is the nature of these tests all Tier-1 production services should be considered "At Risk" during this time. All VOs are asked to give consideration with respect to possible unexpected outage to any high priority/critical jobs they may wish to run during this period.
Open
GGUS Tickets (Snapshot taken during morning of the meeting). |

Notes from Meeting. |
- MICE
- Will create a (GGUS) ticket to record the Castor file permission changes
- SKA
- There is an ongoing permissions problem that causes FTS file transfers to Echo to fail to overwrite files.
- Need to resolve the access to various Rucio machines for the SKA contact in this area.
- Question about FTS transfers appearing as either belonging to the SKA VO or to the individual submitter.
- A couple of batch worker nodes are reserved for the SKA multi-core jobs (i.e. for those requiring a large number of cores).
- Dune
- Job Submissions. These are OK through ARC-CE01, ARC-CE02 and ARC-CE04. Awaiting confirmation that job submission via ARC-CE03 is now OK.
- Dune are carrying out data transfer tests. There is a problem with use of our UK-CA (IGTF) certificates. There is a workaround in place but some more definitive solution is needed.
- Euclid
- An RT ticket has been created to track progress. There is a problem getting the Euclid environment in our Docker images and an issue of job sequencing.
- Procedure Improvements:
- The Grafana plot of non-LHC VO batch jobs was presented. This provides useful information. Some details of the layout to be tweaked.
