Description of problem:

As described in the Jira case OCPBUGS-773, the file /var/lib/containers/storage/overlay/backingFsBlockDev is deleted randomly on nodes with in clusters.

Reviewing all the available Must-gather attached to the Jira case (This Comment) we have noticed that the Operator packageserver is installed in all cluster (version 0.17.0 => 0.19.0)

Version-Release number of selected component (if applicable):

version 0.17.0 => 0.19.0

How reproducible:

The issue is random on nodes and rare.

Steps to Reproduce:

Unknown

Actual results:

Before the fix provided in OCPBUGS-773, the file /var/lib/containers/storage/overlay/backingFsBlockDev was removed and not created, leading the POD to be stuck while trying to be created on the node.

Expected results:

The file /var/lib/containers/storage/overlay/backingFsBlockDev not to be removed and maybe ensure that no other file may be impacted by some kind of clean-up completed by the Operator.

Additional info:

So far the issue is managed at the crio level, monitoring the file.
But it will be great if you can check on the packageserver code and ensure that it's not doing something crazy 😉
