根据我们Kubernetes部署的neo4j 4.2的一部分，我们得到了这个异常。我们只有一个吊舱在运行，现在它进入了崩溃状态。后端是谷歌的文件存储，但目前还没有人访问它。需要帮助-

不建议使用google filestore代替常规的持久卷声明;出于性能原因，Neo4j需要高速、高性能的本地磁盘，通常他们推荐使用ssd。使用像云抽象这样的文件存储，如果它工作的话，可能会导致性能下降。
一般来说，您看到的错误是指磁盘上的文件被另一个进程锁定。这可能是因为Neo4j的上一个(崩溃的)版本锁定了它，或者可能是由于容量问题，这里您必须深入研究filestore如何在GKE之类的东西上提供POSIX投诉驱动器。
