Question

我的分布式geode系统刚好过去，但最近没有，我不知道它是否与昨晚公司的停电有关。似乎所有geode数据都存在之前无法反序列化。

这是错误信息：

我的项目是基于play框架构建的，我的geode缓存和区域配置如下：

cache.setIsServer(true);

    diskStorage = configuration.getString("geode.storage.name");
    String fileStorage = configuration.getString("geode.storage.path");
    cache.createDiskStoreFactory()
            .setDiskDirs(new File[]{new File(fileStorage)})
            .setDiskUsageWarningPercentage(0.8f)
            .setAutoCompact(true)
            .create(diskStorage);

geodeCache.getCache()
            .<DataKey, When2GoData>createRegionFactory(PARTITION_REDUNDANT_PERSISTENT_OVERFLOW)
            .setStatisticsEnabled(true)
            .setEntryIdleTimeout(new ExpirationAttributes(TIMEOUT_LONG, ExpirationAction.DESTROY))
            .setDiskStoreName(geodeCache.getDiskStorage())
            .setPartitionAttributes(new PartitionAttributesFactory<>()
                    .setRedundantCopies(REDUNDANT_COPIES)
                    .setPartitionResolver(new DataKey())
                    .create())
            .create("xxx");

cache = new CacheFactory()
            .set("locators", configuration.getString("geode.locator"))
            .set("name", configuration.getString("geode.name")+ "-"+ uuid)
            .set("mcast-port", "0")
            .set("log-level", "error")
            .setPdxPersistent(true)
            .setPdxReadSerialized(true)
            .create();

以下是readPdxSerializable方法的相关代码：

PdxType pdxType = gfc.getPdxRegistry().getType(typeId);
if (logger.isTraceEnabled(LogMarker.SERIALIZER)) {
    logger.trace(LogMarker.SERIALIZER, "readPdxSerializable pdxType={}", pdxType);
}
if (pdxType == null) {
  throw new IllegalStateException("Unknown pdx type=" + typeId);
}

所以看起来你的缓存中有一些东西你不能再反序列化......因为（我认为）这个类型不再在类型注册表中注册了。

未知的pdx类型= 4
