Quiet Christmas aside from disk server issues.
Major failure on gdss745 (atlasStripInput), possible loss of the whole server.

LHCb DB thread count increase worked (?); on Monday plan to reduce back to original setting (maybe in 2-3 steps)
Operation news
Plans for next week
Work on cattle headnodes.
Long-term projects
CASTOR stress test improvement - Script writing, awaiting testing and validation
Headnode migration to Aquilon - Stager configuration almost complete; functional tests pass. Focus on features but not personalities
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: Turn CASTOR SRMs & other Aquilonised nodes from clients to servers
GP/RA to chase up Fabric team about getting action on RT197296(use fdscspr05 as the preprod stager - replacement for ccse08)
Staffing
GP out until 15th January
RA on call
