我正在尝试创建一个可以将条目写入磁盘的缓存。它在我在 Windows 上的测试中运行良好，但是当我在 IBM z/OS USS 上部署它时，我最终出现以下错误。我的目录中有 0777 并且磁盘上有足够的可用空间。df -k 给我 405591/901440 的可用/总计。对我应该寻找诊断的任何见解都会有所帮助。以下是我的缓存配置-

CacheManager cacheManager = CacheManagerBuilder.newCacheManagerBuilder().with(new CacheManagerPersistenceConfiguration(new File(CACHE_DIR, "DictionaryCache")))
        .withCache("dictionaryCache", CacheConfigurationBuilder.newCacheConfigurationBuilder(Integer.class, KeywordDictionary.class,
                ResourcePoolsBuilder.newResourcePoolsBuilder()./*offheap(200, MemoryUnit.MB).*/disk(200, MemoryUnit.MB).heap(20, EntryUnit.ENTRIES))
                .build()).build(true);
