以防万一对其他人来说真的很重要 - 上面没有帮助我，但json导出/导入一个。
在我的情况下，nexus运行在官方的docker镜像中，所以
docker exec -it nexus bash
或者您访问nexus shell
cd /tmp
/opt/jdk1.8.0_141/bin/java -jar /opt/sonatype/nexus/lib/support/nexus-orient-console.jar
CONNECT plocal:/nexus-data/db/component admin admin
export database component-export
drop database
create database plocal:/nexus-data/db/component
import database component-export.json.gz
在您的情况下，java路径可能会有所不同，我们用来连接/创建数据库的数据路径（nexus数据）也是如此。
之后，重新启动服务和组件数据库应该再次启动并运行
由于不干净关机，我们在Nexus OSS版本3.2.0-01和OrientDB损坏状态方面遇到了类似的问题。
在我们的例子中，损坏的存储是位于的组件

根据Nexus支持，您可以使用Nexus OSS verison 3.2.1-01访问Orient DB控制台。一切都解释了here。在对数据库应用任何操作之前，请确保正确关闭Nexus应用程序。
进入Orient DB控制台后，使用连接到本地数据库
> CONNECT PLOCAL:${your_install_dir}/sonatype-work/nexus3/db/${database} admin admin
然后执行以下操作：
> REBUILD INDEX *
> REPAIR DATABASE --fix-graph
> REPAIR DATABASE --fix-links
> REPAIR DATABASE --fix-ridbags
> REPAIR DATABASE --fix-bonsai
> DISCONNECT
我完全清楚我的答案可能无法解决您的具体问题，但我仍然想给您一些指示，因为您没有任何备份。
数据库预写日志已损坏。
备份$install-dir/sonatype-work/nexus3/db/component，然后从该目录中删除扩展名为.wal的文件。然后再次尝试启动
如果问题仍然存在，请尝试清除“DB”目录下的所有.wal文件，将解决问题，
我确实尝试过这种方法，它就像魅力一样。
关于vinay
使用Nexus 3.16，现在有一项任务：创建修复 - 从blob存储中协调组件数据库
超级慢，但它有助于重新创建仍在磁盘上的意外删除的blobstore。
