Operation problems
gdss746 went out of production
lcgsrm11 (gen) failed and had to be re-installed RT198211
lhbDst is almost full (%2 free space is left) which caused problems to LHCb GGUS132094

Operation news
Completed SL7 upgrade of the Facilities tape servers
Plans for next week
Upgrade of the non-LHCb SRMs to 2.1.16-18 on Wed 06/12
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.
Special topics
Patching - consider turning repeatedly re-used patching plan into standard procedure.
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/GP: 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 to chase up Fabric team about getting action on RT197296(use fdscspr05 as the preprod stager - replacement for ccse08)
Staffing
GP on call
RA out until 6th December
