This could also result in a very high log volume. Can you use a metric instead? There was a problem hiding this comment.

I could add additional metrics as well, but after thinking this over a bit, I wasn't sure what kind of metric to add. Are you thinking of a counter each time this failure happens? Or something else? |

When this is called as part of postUnseal(), as best as I can tell, we're passing an empty context all the way through these methods, originating here: https://github.com/hashicorp/vault/blob/main/vault/core.go#L1693 That means the namespace specific path that we need to add to the path won't exist in the context, as Taint() expects it to. Instead, we use the namespace specific path from the mount entry.
