Operation problems

  * gdss737 failed and brought to production after drive replacement

  * genTape load issue again; ilc and na62 trying to do things at the same time: try a bulk recall of ca. 50 files  
    and see how fast 
      Noted that gdss745 and gdss752 have odd ganglia readings, i.e noe data is read from them

  * Transfers from RAL_Disk to Florida (CMS) are failing GGUS ticket

Plans for next few weeks

   * RA to finish developing the new information system for tape

   * Decommission 2011 genTape disk servers

Long-term projects

Headnode migration to Aquilon - The former vcert headnodes have been configured as CASTOR macroheadnodes and they pass functional tests Sl7 name severs installs ok. Next step: HAproxy

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

RA writing a new accounting system to match WLCG archival requirements

Actions

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
