遇到问题：nexus磁盘满了，当清理出一些空间后，发现能正常上传assets，但是通过API调用时，无法查询assets

根因

因为磁盘满了的时候，nexus的orientdb数据库文件损坏了。导致调用API时报错：Exception 241F5D11 in storage plocal:/nexus-data/db/component

解决办法

参考：
进入到nexus db目录下，找到对应的component目录，

cd /usr/local/soft/sonatype-work4/nexus3/db/component
rm -rf *.wal
java -jar /usr/local/soft/nexus-3.13.0-01/lib/support/nexus-orient-console.jar
CONNECT PLOCAL:/usr/local/soft/sonatype-work4/nexus3/db/component admin admin
REBUILD INDEX *
REPAIR DATABASE --fix-graph
REPAIR DATABASE --fix-links
REPAIR DATABASE --fix-ridbags
REPAIR DATABASE --fix-bonsai
DISCONNECT

以root用户进入nexus的docker容器内，授权目录给所有用户

docker exec -it -u root  4344ab1ab44e sh
chmod 777 -R  /nexus-data/nexus/db

重启nexus容器即可

参考脚本命令
