Why does the disk performance preflight not work in ITRS Analytics 2.18.2 or 2.18.4?

In affected ITRS Analytics 2.18.2 and 2.18.4 releases, the iax-troubleshoot chart can use an incorrect platformTools image tag. When this happens, preflight-related features may not work correctly, including the disk performance test in the KOTS Admin Console.

How can I work around this issue? Copied

Before you install, upgrade, or save the configuration for an affected release, add the appropriate override in the Helm Chart Values Override advanced setting.

For ITRS Analytics 2.18.4, use:

iax-troubleshoot:
  iax-troubleshoot:
    platformTools:
      image:
        tag: 2.18.5

For ITRS Analytics 2.18.2, use:

iax-troubleshoot:
  platformTools:
    image:
      tag: 2.18.5

Note

ITRS Analytics 2.18.4 uses the newer override structure for Helm Chart Values Override entries. For more information, see the upgrade notes.

How do I run the preflight checks manually? Copied

If the preflight feature in KOTS does not complete successfully, run the preflight check manually instead.

You can also disable the Run Disk I/O Performance Test option in the KOTS Admin Console > Advanced Settings.

For bring-your-own-cluster (BYO) deployments:

kubectl preflight cm/itrs/iax-preflight

For embedded-cluster (EC) deployments:

kubectl preflight cm/kotsadm/iax-preflight

If the KOTS preflight screen still shows the disk performance test, skip that test and continue by using the manual preflight command that matches your deployment type.
