RAL Tier1 Operations Report for 1st April 2015
Review of Issues during the fortnight 18th March to 1st April 2015. |
- There were problems with the argus server that affected batch work on wed 18th March. This as fixed following a callout in the evening.
- A further investigation into the primary Tier1 router on the morning of Thursday 19th March failed to fix the problem whereby the router fails after a few minutes in service.
- A problem was found and fixed that caused gridmap file updates to fail.
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.
