Operation problems
Lost na62 and snoplus files that never migrated to tape
OPS tests for WLCGTape are failing and a change in static ldif file needs to be made
A list of irregular files on fdsdss35 [[1][RT213302]] confirm that tape copies are good
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 after Rob finishes with cleaning it up * Proceed with the atlasStripinput decommissioning
Long-term projects
gsi authentication for xrootd: 1) Return preprod to a working state (done) 2) Ask Raja and Tim to run a functional test on preprod to make sure their prod users work 3) 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)
