Operation problems
gdss762 (atlasStripInput) crashed again
gdss761 (lhcbDst) crashed and removed from prod
Alice used more of the batch farm than they are allowed to and this put a large load on aliceDisk disk servers
Operation news
New check_tape_pools version running on Atlas Stager
Disk space rebalancing on lhcbDst
Plans for next week
Run new check_tape_pools version on all Castor stagers
GP: Fix-up on Aquilon SRM profiles.
Long-term projects
CASTOR stress test improvement - Script writing, awaiting testing and validation
Headnode migration to Aquilon - Stager configuration almost complete, awaiting testing.
Target: Combined headnodes running on SL7/Aquilon - implement CERN-style 'Macro' headnodes.
Draining of remainder of 12 generation HW - waiting on CMS migration to Echo. No more draining ongoing.
Actions
RA to check if the disk server setting, changed to bring disk servers back more quickly after a CASTOR shutdown, is still in place
RA/BD: Run GFAL unit tests against CASTOR. Get them here: https://gitlab.cern.ch/dmc/gfal2/tree/develop/test/
GP/RA to chase up Fabric team about getting action on RT197296(use fdscspr05 as the preprod stager - replacement for ccse08)
Miguel to determine of there is a need to have a nagios test for checking the number of entries on the newrequests table
Staffing
RA back next week
