Operation problems
* gdss771 (lhcbDst) failed and were removed from prod
* gdss757 (cmsDisk) was removed from prod as a precaution
* gdss747 is irretrievably lost - work in progress to clean up stager db
* 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)
Staffing
GP on call
