***aborting after fassert() failure

早期的MongoDB版本是4.2，并且可以正常工作。我需要将其降级到3.6，但失败了。之后，我再次安装了4.2。现在，Mongo 4.2也无法正常工作。

Answer 1

似乎降级/升级损坏的数据库文件。

您是否按照推荐的步骤操作了4.2 to 4.0 downgrade，然后是4.0 to 3.6 downgrade？我不知道存在从4.2到3.6的直接降级。

您可以尝试使用mongod --dbpath /data/db --repair修复数据库。如果失败，则必须删除WiredTiger db文件，然后重新安装mongodb并从备份中还原。
