  • LBTO Remote Observing Science Operations Policy (DRAFT)
    • shared, reviewed, feedback - should be clear where we stand.
      • partners will send us their feedback.
      • CV: send both for the UC next week, move forward.
    • many tools but little guidance. Do we need more explicit guidelines e.g., as sketched here?
      • most partners know what works for them. We'll see at next iteration if there's more needed. LBTO already has experience as we operate remotely,
  • progress with LBC / fedora
    • obs2-4 centos6
    • obs5-6 in the process. SH/LR obs6 almost complete.
    • obs1 / LBC IT 8211 (desktop app shortcut) - it's WIP, pending until everything is "blessed"
  • obs workstations
    • reboot schedule policy: recent obs2 episode (reboot but slow the same night)
      • cpu/ram nothing obvious
      • /tmp directory full (wfs? tbd), lbti wfs computer, soul wfs computer. check what's using this on the obs machine, zabbix is monitoring those locations.
        • swap usage, off ramfs? obs2 8GB, obs1 48GB
      • GCSGUI still a problem? better, but yes maybe not all the time. but use / improve FACSUM instead.
    • luci / 64
  • foreseeable IT budget implication from ROWG (ctd.) - do we need new displays
    • repeat a survey, more input from more people trying.
    • MODS display space hog
  • What's next
    • next meeting Oct 26, same zoom, same time.
