AFS service/operation meeting

AFS operations meeting 2015-06-22

• ABS:  some mails form afscron1 - ignored? dangerous? no, look like usual "CASTOR is busy" send2ns() error; we are no longer using a dedicated CASTOR nameserver..
• ABS: installed on AFS; worried about ability to disaster recovery situation.. (but currently is on 9 replicas). Should be deployed as RPM; Jan will help with .spec file. ABS needs VLDB to be up for full-machine restores (or to get volume list from AFSCONSOLE DB), could also add fileserver name to CASTOR filename.
• ABS: should do a restore exercise at large-but-regular intervals (6months?)
• CC7: test VM set up (in testcell), needs newer OpenAFS (CERN 1.6.7 does not cleanly rebuild). Jan to rebase onto 1.6.11
• OpenAFS mailing list discussion "OpenAFS still in development?" (admin from TU Berlin looking for fresh Windows builds), confirms overall gloomy feeling
• TH/Elena (ticket, triggered by "overload" mails): will talk to her, then organize some "which storage system to use"-tutorial for TH
• WEBAFS replacement via EOS: need to talk to AndreasW. Static content can be served from EOS, but .htaccess and cgi-bin need some intermediate web server (which DSS should not run). Ideally could have self-service "EOS-hosted web page" similar to current "AFS-hosted web page"..
  • needs stable EOS client RPM (still clash with xrootd-4?)
  • might need a migration campaign for 'default' mapping (http://cern.ch/$USER -> /afs/cern.ch/user/U/$USER/www )
• any news on AFS-vs-EOS-FUSE POSIX compatibility test (results)? No.
• OpenAFS workshop - send somebody ? IT/DSS travel budget issues, Massimo will cross-check with Alberto [after meeting: no go]
