MPU Meeting Wednesday 20th June 2018

Inventory

  • Alastair has modified the script to mail the kit lists to people for the laptop audit.
  • The --fields option for the ii command has been improved for Graham.
  • Alastair found an unusual test failure which only occurs approx 1 in 70 runs. This is due to a motherboard replacement which does not return a model name.
  • Stephen queried how RT gets machine information.

Virtual Desktop

LCFG Profile Security

UEFI Boot

SL 7.5

The LCFG level package lists have been generated and the headers have been checked. Stephen has now begun work on the DICE level.

Misc Development

libvirt
Chris is testing the latest libvirt from SL7.5 on circle. A small change is required for the config so that kvmtool create works properly.

Operational

nvidia drivers
Some versions of the nvidia driver needed updating for the new kernel from SL7.5

azul serial console
We need to fix the serial console, maybe we should just switch to an old fashioned serial cable for now?

computing.help and GDPR
Alastair will check with George.

  • Alastair
    • Inventory project
      • continue working through TartarusWorkFlow
      • Document clientreport (eg how to add modules)
      • Document order sync code
      • Document hpreport processing script
      • Start work on final report!

      • Complete removal of non authenticated access to API and web
      • Need tests for API /orders and need new tests to check for correct authorisation
      • Need to check that LCFG header generation is generating stuff for static self-managed machines (as need for DHCP)
      • Make lcfg header generation live (need to check what will be deleted when we do this - big discrepancy between old inventory and new)
      • Look at user support form - how does that lookup hostname?
      • Produce a python library to provide people with a programmatic equivalent of ii query
      • Look at whether there is an easy library way for Chris to grab the macaddr of a machine given the hostname
    • Schedule MPU meeting to discuss systemd ordering
    • Take a look at RT #78875

      • work out what we need to fix current problem
    • Circulate info on RH7.3 systemd changes we may wish to consider
    • RT actions (as agreed)
    • Implement change to kvmtool to allow KVMs to be marked as disabled
      • looked at this - looks like the metadata tag isn't passed through libvirt (prior to 4.0.0), so can't be read/written by kvmtool
      • put on activities list to do once upgrade to libvirt-4.0.0
    • Look at Stephen's 'Thoughts on shell components'
    • Look at MPUActivitiesList
    • Start looking at https and computing.help (remove assumption that https means want cosign login)
      • wait on Neil's efforts with EdWeb
    • Chase Alison about LCFG check monitoring ( start doing again )
    • Investigate systemd reboot bug on gaivota and add some more debugging (store tree diff somewhere)
    • Report on this at next ops meeting that have changed journald configuration (MPU report)
    • Discuss with Neil - drupal username collection re GDPR
      • write a script to remove users who haven't used computing.help in, say 30 days (except COs) - and fix the email address issue (currently defaults to umich.edu)
      • Ask George whether this is covered by legitimate business interest.
    • Inventory stuff re GDPR
    • Check with Tim / George about capability for login to student machines - where are we
    • Add %slaac to hulp and lagun after 21/02/18
    • Useful? - a script which checks how fast a machine's console log is growing (eg huge number of dbus problems on hammersmith)
      • suggest to Ian D
    • Blog on projects
    • KVM pcid
      • Created MPUSpectreMeltdown
      • Put detection script somewhere for people to use
      • Which CPU is needed for each group..
Following config worked on 'brent' (hosted on vermelha). We might need to consider whether we want "match='exact'" wrt migrations.
<cpu mode='host-model' match='exact'>
<model fallback='allow'>IvyBridge</model>
<vendor>Intel</vendor>
<feature policy='require' name='pcid' />
</cpu>
    • Look at why kvmtool doesn't work on circle (running libvirt 4.0.0)

    • Remove IBM disk array from stack * First ask RAT whether they might find the array useful
    • Read Chris's blog on ThoughtsOn403
    • Look at moving stuff from the immediate todo back to the main Todo list and then we can prioritise that list

  • Chris
    • Inventory project
      • Continue work on clientreport modules for replacing firmwarereport
    • Look at MPUActivitiesList
    • Look at RT
    • Continue work on SL7 coordination final project report (currently pending other units completing)

    • Look at where we're using ALL in access.conf
    • Agree with RAT how software package requests are handled - waiting on Graham documenting
