We've noticed some situations where df fails due to the tracer not initializing correctly, and therefore we are unable to determine available disk space. Let's instead fail gracefully when we can't determine available disk space.

My comment shouldn't block having this merged, but something to add later if we want.

Do we want to capture the reason for the df failure and send it as part of the status report?

The message wouldn't make it into kusto, but at least it would be available in splunk.

We could probably add an internal error diagnostic for this. Let's address as potential follow up, as you suggest.
