Review Comment:
I dont have a strong opinion in this specific case.
This is a retriable failure, and could simply succeed on next attempt. Note
that the exception, when if it gets bubbled up (`retried == true`), gets logged
at `INFO` currently (see `loadDiskStore`) - so the `logWarning` level here, to
begin with, looks slightly off.
