Operation problems

  * Load issue on genTape - possible fault with the recently deployed 2013 ds? 
  * Failed snopuls transfers; FTS point : either a issue with gdss766 or FTS/SRM mis-scheduled the transfers RT206651
  * fdsdss21 crashed and removed from production - it is now back in production  

  * ChrisP 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

  * GridPP40 meeting

Plans for next few weeks

  * Incease the slot count on the 2013 genTape disk servers and see if it makes a difference on performance

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

No point to move Atlas and CMS to the macroheadnode setup since their d1t0 data are moving to Echo over the next two months

HA-proxyfication of the CASTOR SRMs: HA proxy set up has been tested on the SRMs

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

Actions

Investigate hte history of the failed files on gdss766

Tell whether a Facilities functional test which was running on on lcgcadm05 is running on castor-functional-test1

JK to investigate why ralreplicas fails and submit a "bug" report

JK to investigate castor functional test on facilities

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

RA to check if there is any outstanding action for Fabric

GP/RA to write a Nagios test to check for large number of requests on the NewRequests DB table that remain for a long time

Staffing

RA on call
