Operation problems

  * Unroutable files to tape from CMS - need to anticipate this

  * Load issue on genTape - possible fault with the recently deployed 2013 ds? Increased slot count 
    on 2013 boxes. Will set the 2011 servers to RO

Operation news

  * Rob has retired fdsadm01 which is the old Fac WebDAV
  * lcgcadm03 and lcgcadm04 have been patched against Spectre/Meltdown

Plans for next few weeks

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

RA/GP to talk to Chris Brew about alerting for new CMS file classes and tape families

RA to remove cedaRetrieve service class from cheksum validation

Investigate the history of the failed files on gdss766 RT ticket

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

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 on the NewRequests DB table that remain for a long time

Staffing

GP on call
