Operation problems

  * Serious firewall misconfiguration resulted in the breaking of external xrootd access to RAL
  * Chris reports that a functional test that used to run on lcgcadm05 doesn't work anymore (probably because the machine has been turned off)
     * Should have been ported to castor-functional-test1 - maybe just needs repointing?

Operation news

  * Aquilon SRM profiles fixed up and deployed to prod
  * lcgcts12 (preprod) upgrade to SL7 properly attached to the preprod instance

Plans for next few weeks

Patching of the Neptune and Pluto DB and testing of switching over to R26 postponed until 27th March.

GP: Continue work on 'macroheadnodes' and write the change control. Deployment of new genTape disk servers.

Long-term projects

Headnode migration to Aquilon - Stager, scheduler, utility and nameserver configuration mainly complete. Stager, scheduler, utility tested seperately and all together on preprod. Combined Stager, scheduler, utility and SRM features in one node which passes functional tests

'Macroheadnode' configuration testable :D

HA-proxyfication of the CASTOR SRMs: HA proxy is back and can be tested on preprod

Target: Combined headnodes running on SL7/Aquilon - implement CERN-style 'Macro' headnodes.

Draining of 4 x 13 generation disk servers from Atlas that will be deployed on genTape - draining complete, waiting for Fabric.

Draining of 10% of the 14 generation disk servers

Actions

RA/BD: Run GFAL unit tests against CASTOR. Get them here: https://gitlab.cern.ch/dmc/gfal2/tree/develop/test/

GP/RA to write a Nagios test to check for large number of requests that remain for a long time
