RAL Tier1 Operations Report for 28th February 2018
Review of Issues during the week 21st February 2018 to 28th February 2018 |
- AliceDisk is getting very full. Alice have been in informed.
- There is an outage on Castor announced for Thursday (1st March) while the database systems have Oracle patches applied.
- The IPv6 connections, both to the RAL Core network and the 'bypass' route were moved to share the IPv4 connections was completed successfully. This was done ahead of a change to enable IPv6 (dual stack) on the Echo Gateways (scheduled for the 27th).
Current operational status and issues |
- The problems with data flows through the site firewall being restricted is still present. New firewall kit has be purchased and delivered, awaiting deployment.
- Echo Gateway Dual Stack upgrade was implemented but appears to have broken RAL FTS. Currently CERN FTS is being used as a stop-gap solution. This issues is on-going at time of writing.
Resolved Castor Disk Server Issues |
- gdss776 (d1t0) - Back in production (RO)
- gdss762 (d1t0) - Back in production (RO)
Ongoing Castor Disk Server Issues |
- None
Limits on concurrent batch system jobs. |
- CMS Multicore 550
Notable Changes made since the last meeting. |
- Move to IPv6 connectivity - currently on 10Gbit links - to share the higher bandwidth (40Gbit) links used by IPv4. This has been approved at the CAB meeting (13/2/18), and will implemented on the 21/2/2018.
Entries in GOC DB starting since the last report. |
- None

Advanced warning for other interventions |
The following items are being discussed and are still to be formally scheduled and announced. |
Listing by category:
- Echo
- Enable IPv6 (idual stack IPv4/6) on Echo gateways
- Castor:
- Update systems to use SL7 and configured by Quattor/Aquilon. (Tape servers done)
- Move to generic Castor headnodes.
- Networking
- Extend the number of services on the production network with IPv6 dual stack. (Done for Perfsonar, FTS3, all squids and the CVMFS Stratum-1 servers).
- Replacement (upgrade) of RAL firewall.
- Internal
- DNS servers will be rolled out within the Tier1 network.
- Infrastructure
- Testing of power distribution boards in the R89 machine room is being scheduled for some time late July / Early August. The effect of this on our services is being discussed.
