Operation problems

 * gdss757 (cmsDisk) was removed from prod as a precaution

 * Unusual high failure rate in LHCb transfers from RAL WN to CASTOR GGUS ticket

Operation news

 * The endpoint for the new CASTOR instance is published on GOCDB as monitored

Plans for next few weeks

  * Push gsi authentication for xrootd in production

  * Decommission gdss747

Long-term projects

gsi authentication for xrootd: 1) Return preprod to a working state 2) Ask Raja and Tim to test the gsi config on preprod 3) Perform a stress test

Things need doing: log rotation, xrootd for ALICE

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 - the check will run every xxx min (to be aggreed with Production) and issue an alarm if the number exceeds 1,000 for an extended period of time (15 min)
