Operation problems

OPS tests for WLCGTape are failing and a change in static ldif file needs to be made

Operation news

 * ATLAS tape test completed successfully on the new CASTOR instance

Plans for next few weeks

  * Push gsi authentication for xrootd in production

  * Decommission gdss747 & gdss753

  * Proceed with the atlasStripInput decommissioning

Long-term projects

gsi authentication for xrootd: 1) Ask Raja and Tim to run a functional test on preprod to make sure their prod users work 2) Perform a stress test

New CASTOR WLCGTape instance: Upgraded stagers and ns nodes to 2.1.17-35. Need to upgrade tape servers to make migrations/recalls to work. Because of CASTOR version depedencies, tape servers cannot all be upgraded and allocated to the new instance at the same time. Rob suggested we do 5 tape servers for every VO migration to the new CASTOR instance. Also need to negotiate with TimA how many tape drives ATLAS would be happy to use for the tape "carouselle" test.

Things need doing: log rotation(RT212634), xrootd for ALICE

Actions

GP to add ldif entry for the new srm-wlcgtape endpoint

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

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)
