RAL Tier1 Operations Report for 6th May2015
Review of Issues during the three weeks 15th April to 6th May 2015. |
- On Wednesday 8th April a minor network change triggered a wider problem across the Tier1 network and caused significant disruption of services. The planned Castor upgrade for that day had to be abandoned. A post mortem is being generated for this incident.
Resolved Disk Server Issues |
- GDSS633 (AtlasTape - D-T1) failed on Sunday 3rd May. It was returned to service late evening the following day (Bank Holiday Monday 4th May).
Current operational status and issues |
- We are running with a single router connecting the Tier1 network to the site network, rather than a resilient pair.
- The bypass link from the Tier1 to the UKLR has been restored to 2 x 10Gb/s but traffic going outbound is not being correctly balanced across the two links. This is still under investigation.
- Since 27th March there has been sporadic low level packet loss on the OPN primary link to CERN. This is being investigated.
Ongoing Disk Server Issues |
- None
Notable Changes made this last week. |
- Castor was successfully upgraded to version 2.1.14-15 this morning.
- gfal2 and davix rpms are in the process of being updated across the worker nodes.
Declared in the GOC DB |

All Castor (All SRMs) | SCHEDULED | OUTAGE | 15/04/2015 09:30 | 15/04/2015 15:30 | 6 hours | Castor upgrade to 2.1.14-15 as this was postponed last week. |
Advanced warning for other interventions |
The following items are being discussed and are still to be formally scheduled and announced. |
- Turn off CREAM CEs (planned for 5th May).
- Turn off ARC-CE05. This will leave four ARC CEs (as planned.) This fifth was set-up to temporarily workround a specific problem and is no longer required.
Listing by category:
- Databases:
- Switch LFC/3D to new Database Infrastructure.
- Update to Oracle 11.2.0.4. This will affect all services that use Oracle databases (Castor, LFC and Atlas Frontier)
- Castor:
- Update SRMs to new version (includes updating to SL6).
- Fix discrepancies found in some of the Castor database tables and columns. (The issue has no operational impact.)
- Networking:
- Separate some non-Tier1 services off our network so as to be able to more easily investigate the router problems.
- Resolve problems with primary Tier1 Router
- Enable the RIP protocol for updating routing tables on the Tier1 routers. (Install patch to Router software).
- Increase bandwidth of the link from the Tier1 into the RAL internal site network to 40Gbit.
- Make routing changes to allow the removal of the UKLight Router.
- Fabric
- Firmware updates on remaining EMC disk arrays (Castor, FTS/LFC)
