RAL Tier1 Operations Report for 12th August 2015
| Review of Issues during the week 29th July and 5th August 2015. |
- There was a site network outage on Saturday 8th August. The Tier1 was affected from approx 07:30 until 10:00. The issue was resolved when a member of the network team came on site and re-seated a card in a router.
| Resolved Disk Server Issues |
- None.
| Current operational status and issues |
- The post mortem review of the network incident on the 8th April is being finalised.
- The intermittent, low-level, load-related packet loss over the OPN to CERN is still being tracked.
- There are some on-going issues for CMS. These are a problem with the Xroot (AAA) redirection accessing Castor; Slow file open times using Xroot; and poor batch job efficiencies.
| Ongoing Disk Server Issues |
- gdss720 (part of ATLASDATADISK) crashed on Tuesday 11th. The machine is currently being drained so the fabric team can replace some components.
| Notable Changes made since the last meeting. |
- Atlas have transferred a share of their FTS service back to RAL.
- The test of the updated worker node configuration (with grid middleware delivered via CVMFS) continues on a one whole batch of Worker Nodes. We are now draining a second batch of worker nodes.
- Investigative work into the ongoing issues for CMS Castor. This included putting the CMS xroot reads through the Castor scheduler again.
| Declared in the GOC DB
None |
| Advanced warning for other interventions |
| The following items are being discussed and are still to be formally scheduled and announced. |
- Upgrade of Castor disk servers to SL6. We plan to do this during the second part of August (17-28). Rollout plan to be discussed.
- Upgrade of the Oracle databases behind Castor to version 11.2.0.4. This is a multi-step intervention. Whilst we need to confirm exact dates we are looking at the following days in September:
- Tuesday 8th: day's Outage for Atlas & GEN.
- Tuesday 15th: at risk on Atlas & GEN.
- Thursday 17th: day's Outage for ALL instances.
- Tuesday 22nd: day's at risk for ALL instances
- Thursday 24th: Half day outage for ALL instances.
- Extending the rollout of the new worker node configuration.
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, Atlas Frontier (LFC done)
- Castor:
- Update SRMs to new version (includes updating to SL6).
- Update the Oracle databases behind Castor to version 11.2.0.4. Will require some downtimes (See above)
- Update disk servers to SL6.
- Update to Castor version 2.1.15.
- Networking:
- 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.
- Cabling/switch changes to the network in the UPS room to improve resilience.
- Fabric
- Firmware updates on remaining EMC disk arrays (Castor, FTS/LFC)
