RAL Tier1 Operations Report for 14th February 2018
Review of Issues during the week 7th February 2018 January 2018 to 14th February 2018 |
- We had an incident with our disk servers that deal with tape recalls/migrations on our Gen instance. A network misconfiguration was introduced after they had been physically move to a new rack location last Thursday. As a result, tape transfers were not running over the weekend, with this issue being resolved on Monday morning. We are holding a post-mortem review on this incident with the view of improving the relevant processes and to ensure we reduce the risk of this problem happening again.
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.
Resolved Castor Disk Server Issues |
- None
Ongoing Castor Disk Server Issues |
- None
Limits on concurrent batch system jobs. |
- CMS Multicore 550
- ALICE jobs 750. (Attempt to re-balance farm)
Notable Changes made since the last meeting. |
- The Upgrade of Echo to the latest CEPH release (“Luminous”) was carried out successfully during the second half of last week. This was done as a rolling update with the service available throughout.
- ALICE VOBOXes (lcgvo07 and lcgvo09) and LHCb VOBOX (lcgvo10) are now dual stack IPv4/6.
- The Hyper-K VO has been enabled on the batch farm.
- Atlas have moved their FTS transfers from our "test" FTS service to the Production one. This change was made at our request and effectively consolidates us with a single production FTS service.
Entries in GOC DB starting since the last report. |
- None
Declared in the GOC DB |
- No downtime scheduled in the GOCDB between 2018-02-07 and 2018-02-14
Advanced warning for other interventions |
The following items are being discussed and are still to be formally scheduled and announced. |
Ongoing or Pending - but not yet formally announced:
- Move IPv6 connectivity - currently on 10Gbit links - to share the higher bandwidth (40Gbit) links used by IPv4.
Listing by category:
- 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).
- Move IPv6 connectivity - currently on 10Gbit links - to share the higher bandwidth (40Gbit) links used by IPv4.
- 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.
