Operation problems

on 2013 boxes. Will set the 2011 servers to RO

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.

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
