Upgrade eqiad/codfw Ganeti clusters to Buster
Open, MediumPublic


Edge ganeti clusters were setup with Buster from the start, but eqiad/codfw are still in need of an update:

  • Import the last backport of ganeti 2.16.0-1~bpo9+1 to a repo component and add to Ganeti/stretch
  • Upgrade a single node to 2.16 and test (verify, verify-disks, create new VM, start/stop)
  • Upgrade remaining stretch nodes to 2.16
  • Run gnt-cluster renew-crypto (for SHA256 compat)
  • Run gnt-cluster upgrade
  • For each stretch host:
  • Empty a node of VMs with gnt-node migrate / gnt-node evacuate -s
  • Reimage to buster (which also brings new qemu compared to before)
  • Re-add the node and test
  • Move back VMs
