• eos-4.3.11 is now in "qa"  (btw - no release announce?) - CRM-2823
• FUSEX / microtests: reduced coverage from "microbench" to "ci"
  • since reverted since no fresh Grafana data - need to kick out too-slow tests, or see why no data got sent.

(andreas) - things below are not yet tagged.

• tracked LHCB QA machine problems with EOSXD down to 'out of filedescriptor' case
  • prevents reading /proc entries to assign kerberos token (falls back to unix in this cases, gives "permission denied" to client)
  • moving to 512k as default (had use case merging 10-100k files)
     
• observed memory aggregation on HOME migration machines (4-6 GB RSS)
  • improved memory release functionality, now back to initial RSS after 8min (helps on non-automount, otherwise would not release back memory. Would explain observed OOM of EOS FUSEX daemons)
     
• disabled a main performance bottleneck config value, which requires create/open(w) to wait for creation on both FSTs
  • this had been enabled because recovery wasn't working reliable (yet)
    • data is still in local journal, but might be lost after a client crash (missing credentials)
  • was triggered by FORTRAN microtest

Note: AIADM-EOS test cluster is being set up by CDA ($HOME dir on /eos), discovering known issues (slow GIT commands?, incl "git status") "EOS migration" is being misunderstood?
