Ubuntu22: Mitigation for waagent's failure register DNS #205

Closed ryanhamel closed 6 months ago

ryanhamel commented 6 months ago

Ubuntu 22 or greater and DNS hostname resolution Due to an issue with the underlying DNS registration scheme that is used across Azure, our Slurm scripts use a mitigation that involves restarting systemd-networkd when changing the hostname of VMs deployed in a VMSS. This mitigation can be disabled by adding the following to your Configuration section.

  [[[configuration]]]
  slurm.ubuntu22_waagent_fix = false

In future releases, this mitigation will be disabled by default when the issue is resolved in waagent. Fixes: #203
