> Kahadb checkForCorruptJournaFiles will pick up journal corruption via the checksum, but
if the corrupt locations are not referenced by the index the corruption is ignored, even if
ignoreMissingJournalFiles (which should be called ignoreMissingJournalFilesOrCorruptJournalLocations)
is false (the default).
> this means that acks can be missing and in the event of a journal replay, there is no
indication of the missing acks.
> If ignoreMissingJournalFiles=false and corruption or missing journal files that just
have acks are detected, the broker should error out.
> This ensures that corruption does not go unnoticed and the root cause can be determined
before restart.
