RAL Tier1 Operations Report for 23rd April 2018
| Review of Issues during the week 16th April to the 23rd April 2018.
|
- The upgrade (replacement) of the RAL firewall is scheduled to take place on the morning of the 25th April. Hopefully this will fix problems we have seen with data flows to/from our worker nodes.
- A chassis needs replacing has almost all the services that DS provide to the whole STFC going through it. The chassis also has DNS (IPV4 & V6) which will potentially (read as 'will'), affect some of the transfers that Tier-1 are part of. This is to be scheduled three weeks time, however if required (i.e. the chassis state deteriorates further), then this will be done sooner as an emergency intervention.
| Current operational status and issues
|
- The problems with data flows through the site firewall being restricted is still present. New firewall equipment has been delivered and is now scheduled for deployment 25th April 2018.
| Resolved Castor Disk Server Issues
|
- gdss782 (atlasStripInput - D1T0) - Back in full production.
| Ongoing Castor Disk Server Issues
|
- gdss756 (genTape - D1T0) - Currently out of production awaiting investigation by the CASTOR and Fabric teams.
| Limits on concurrent batch system jobs.
|
| Notable Changes made since the last meeting.
