Sonotype Nexus Repository/OrientDB 无法连接到数据库

Question

昨天我们的 nexus 存储库实例由于磁盘已满事件而横盘整理。释放一些空间并尝试重新启动后，nexus 不再可用。结果，数据库损坏（大概）并且无法连接。当我运行 nexus-orient-console.jar 进行连接时，这是我得到的：

orientdb> CONNECT plocal:/nexus-data/db/component admin admin

因为我什至无法连接到数据库，所以我无法尝试此处建议的恢复步骤 > OrientDB Nexus Repository version 3.2.0-01 中的损坏状态。有没有办法修复和恢复数据库，或者我们只是SOL？有没有办法在忽略数据库问题的安全模式下启动 nexus？

该线程必须解决我们的问题。 https://groups.google.com/a/glists.sonatype.com/g/nexus-users/c/64W_y9fDGzQ/m/o0FKRgiDAwAJ?pli=1

总而言之，此步骤修复了我的错误（与您相同）：

rm /mnt/sonatype-work/nexus3/db/config/*.wal

然后尝试启动控制台并修复数据库

在 orientdb 提示符下运行以下命令：

connect plocal:/mnt/sonatype-work/nexus3/db/confg admin admin
repair database --fix-links
rebuild index *
disconnect 
exit

对于 Nexus 3.2.1+，可以使用附带的 OrientDB 客户端。
