RAL Tier1 Operations Report for 16th July 2018
Review of Issues during the week 9th July to the 16th July 2018. |
- Tier-1 has been very much business as usual this week. The only incident of real note was the loss of an Atlas server(gdss747 - d1t0). This incident involved a lost drive that was found to be not recoverable. Subsequently a data loss declared. Under normal circumstances this would be considered a serious incident, however Atlas are all but complete in the process of migrating from CASTOR to ECHO. As such, no primary data had been lost with 89% of lost data comprising log files.
