RAL Tier1 Operations Report for 30th October 2018
Review of Issues during the week 29th October 2018 to the 30th October 2018. |
- Availability of the CMS-AAA service is improving. Machines have had their memory doubled, which has stopped the machines going in to swap. The other problem is a bug which is fixed in a later version of XRootD than we are running. We will need to recompile XRootD, create an RPM and deploy as appropriate.
- Patching of machines against CVE-2018-14634 is in progress. The WN which were the most at risk of being exploited by this vulnerability were done on the 22nd - 23rd October. We still need to reboot around 500 other machines (total 1500).
- OPs tests are finally passing for Echo solving a ticket that was open for nearly 2 years!

The following items are being discussed and are still to be formally scheduled and announced. |
Listing by category:
- Castor:
- Disk only storage will end in Castor. A new single tape-only Castor instance (called WLCGTape) is being tested. This is using generic Catsor headnodes on SL7 configured by Quattor/Aquilon with a slightly newer Castor version.
- Update systems to use SL7 and configured by Quattor/Aquilon. (Tape servers done)
- Internal
- DNS servers will be rolled out within the Tier1 network.
