Как исправить недопустимое хранение данных на неопределенное время?
У меня есть приложение, которое использует Modeshape (версия 4.2.0.Final) и Infinispan (версия 6.0.2.Final). Во время недавнего простоя кажется, что мое бесконечное хранилище сломалось, потому что теперь я не могу получить данные из этого хранилища с такими исключениями, как

Мой бесконечный кластер настроен с использованием этого XML

как упоминалось ранее, все вышло из строя во время простоя, но как я могу восстановить это хранилище данных?

Там нет fsck-как инструмент для несогласованного хранения. Тем не менее, формат хранилища отдельных файлов довольно прост (см. https://github.com/infinispan/infinispan/blob/6.0.x/core/src/main/java/org/infinispan/persistence/file/SingleFileStore.java), чтобы вы могли написать свой собственный читатель и проанализировать, что не так.
