This Week

  • Alastair
    • Inventory project
      • continue working through InvProjectWorkFlow
      • Document clientreport (eg how to add modules)
      • Document order sync code
      • Document hpreport processing script
      • Start work on final report!
      • and give details on how Tartarus tables are accessed to Ian D for inclusion in his privileged access discussion paper
      • Look at postgresql replication (do after shipping)
      • Add tartarus info to SwitchToSelfManaged
      • Need tests for API /orders and need new tests to check for correct authorisation
      • 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?
      • Look at whether there is an easy library way for Chris to grab the macaddr of a machine given the hostname
      • Add dmidecode to installroot, fixup install.patchurl and locate the serial number grabber appropriately and then document process for machines with multiple serial numbers.
    • Schedule MPU meeting to discuss systemd ordering
    • Take a look at RT #78875
    • Look at /etc/hosts - dns issue (IPV6?)
      • work out what we need to fix current problem
    • 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'
    • Start looking at https and computing.help (remove assumption that https means want cosign login)
      • wait on Neil's efforts with EdWeb
    • Investigate systemd reboot bug on gaivota and add some more debugging (store tree diff somewhere)
    • drupal username collection re GDPR
      • configure live server to run the user expiry script
      • Fixup email domains for existing accounts and check fix for domain setting to inf.ed.ac.uk is in place on live service
      • need to ship fixed cosign module on live service
    • Inventory stuff re GDPR
    • Check with Tim / George about capability for login to student machines - where are we
      • Tim says that we should create a capability that is given to the base cohort and set that capability to no-grace
    • 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
      • Investigate spectre / meltdown wrt VMs
      • 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>
      • Update: looked at this. We should be safe to set CPU model to host-model on clusters where the CPU is identical across the cluster (KB and AT). However we can't where the CPU's aren't identical (IF) - here we should be able to set a base minimum machine (SandyBridge ?). We'd need to check that migration works. Recent versions of virsh allow you to specify the hosts in the cluster and ask for a CPU model description which will work across all the cluster. Setting the base minimum to SandyBridge on 'oyster' fixed one of the Spectre flaws, but not all. It looks like we need a more up-to-date qemu-kvm to fix all the remaining flaws. * Wait until 7.6ish is settled re KVM software versions and try above again * Need to disable hyperthreading on all KVM servers
    • Move IBM disk array to B.03 and mark as junk
    • Produce some notes from OSS
