AFS operations meeting 2015-09-21

Issues:

  • afsdb5 is now in "qa"
  • need to split up existing LanDB set (different ports for FS and DB, ideally get test machines out of the firewall); created new sets and asked for firewall openings (duplicate), eventually remove from old set
  • afs255, afs270 both locked up (affected GIT, ATLAS)
    • should discuss evolution with GIT people
    • how to auto-detect? invoke_accesstimes" - was sometimes actually working. Look for stuck "vos exa", "vos listvol"
    • restart may fail (even when waiting for 15min)
  • CMS "AFS is slow" thing on weekend, correctly self-diagnosed.
  • increase number of fileserver threads?
  • AFS CASTOR backup is "slow" - are we piling up transfers in CASTOR?
There are minutes attached to this event. Show them.
