RAL Tier1 Operations Report for 15th April 2015
| Review of Issues during the week 8th to 15th April 2015. |
- On Wednesday 1st April there was a problem with the Argus service. The service was restarted before there were any tickets.
- On Thursday 2nd April, a HyperVisor locked up and this caused a production squid and a test fts machine to be unavailable for some hours.
| Resolved Disk Server Issues |
- None
| 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.
| Ongoing Disk Server Issues |
- None
| Notable Changes made this last week. |
- gfal2 and davix rpms are in the process of being updated across the worker nodes.
| Declared in the GOC DB |
| Service | Scheduled? | Outage/At Risk | Start | End | Duration | Reason |
|---|---|---|---|---|---|---|
| All Castor (all SRM endpoints) | SCHEDULED | OUTAGE | 08/04/2015 10:00 | 08/04/2015 14:00 | 4 hours | Upgrade of Castor storage to version 2.1.14-15 |
| Advanced warning for other interventions |
| The following items are being discussed and are still to be formally scheduled and announced. |
- Separate some non-Tier1 services off our network so as to be able to more easily investigate the router problems.
Listing by category:
- Databases:
- Switch LFC/3D to new Database Infrastructure.
- Update to Oracle 11.2.0.4
- 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:
- 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)
