AFS service/operation meeting

AFS operations meeting 2016-03-07

present: Dan, Jan, (Massimo)

Issues:

• re-UID campaign still ongoing, restarted for E.McIntosh files (many scattered over different BOINC-user volumes)
  • SIXTRACK BOINC could perhaps benefit from new IT consultancy service (parameter sweep files (10.20M) -> DB? output file merge step?)
• removed swap from AFS servers
• tweaked LEMON disk-full exception to give poolmonitor a chance to drain (fills up to 90%, hardcoded)
• disabled Thu morning "client stat" script. No issues reported this Thu, but blind..
• more aggressive tracing on 'reschedule' messages (after seeing some p.atlas.root overloads without indication where these came from)...
• OpenAFS client unhappiness:
  • Windows SHA1 deprecation - unclear whether this affects all attempts to execute on all clients, or only new installs with code signed after 2016 (OpenAFS got signed in 2014?). Can CERN (re-)sign & distribute? --> ticket
  • Linux 4.4 kernel issues on mailinglist: can't compile, might corrupt data? looks like Marc Dionne used to maintain the kernel parts (until 4.2), but (relatively) recently got hired by AuriStor
