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

Corrupted/incompletely written files due to 20/11 power outage

SOLID access/ceritificate issues GGUS131840

Operation news

Completed SL7 upgrade of the Facilities tape servers. Memory issues due to wrong configuration on Aquilon resolved

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.

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
