Ubuntu 20.04 on ESXi Generating multipathd Errors

Posted on 03-Jun-2020 by krylon

Brand new install of Ubuntu 20.04 LTS (Focal Fossa) running as a virtual machine on ESXi was generating a lot of errors in syslog like the below

multipathd[711]: sda: failed to get udev uid: Invalid argument
multipathd[711]: sda: failed to get sysfs uid: Invalid argument
multipathd[711]: sda: failed to get sgio uid: No such file or directory
multipathd[711]: sda: add missing path

The solution is to edit the configuration of the virtual machine using the steps shownb elow for ESXi 6.7. Source https://ubuntuforums.org/showthread.php?t=2441797

  1. Shut down the VM
  2. Edit the VM -> Edit settings -> VM Options
  3. Under Advanced ->Configuration Parameters -> click Edit Configuration button
  4. Add a new parameter with following properties:
    Key: disk.EnableUUID
    Value: TRUE
  5. Click OK -> Save
  6. Power on the VM and confirm the errors have stopped in /var/log/syslog
