Windows版Nexus因磁盘空间占满导致orientdb数据损坏修复

由于年底公司项目多，大量程序打包，导致windows虚拟机用于存放库文件的nexus所在磁盘空间减少，jenkins打包和本地发布jar包出现无响应情况，开始怀疑为磁盘空间不足导致，关闭系统扩展了虚拟机磁盘空间，但是依旧无法启动服务，查看“E:\Nexus\sonatype-work\nexus3\log”下的日志报如下：

经网上查询为磁盘空间不足导致数据库文件损坏！但是查看修复方式几乎全是linux上的，按照其步骤尝试发现修改一些方式后可修复，为防止原作者删除文档，故修改为windows版发布。

执行指令：

E:\Nexus\nexus-3.11.0-01\jre\bin\java -jar E:\Nexus\nexus-3.11.0-01\lib\support\nexus-orient-console.jar

此指令是进入orientdb数据库工具包，nexus自带，且可用自带的jre运行。

在工具包运行下的命令行执行指令：

CONNECT PLOCAL:E:/Nexus/sonatype-work/nexus3/db/component admin admin

 注意：windows复制出来的“\”要全改成“/”否则将会报错，路径不识别。

通常数据库损坏时，该方式现无法访问数据库。

输入“exit”指令，退出工具包程序，到“E:\Nexus\sonatype-work\nexus3\db\component”目录下，删除所有wal后缀的文件。

然后执行上方指令重新进入工具包（忘记要不要登录到component 下了，因无损坏环境，故可先尝试是否可admin登陆，再执行指令），逐条执行如下指令：

REBUILD INDEX *

REPAIR DATABASE --fix-graph

REPAIR DATABASE --fix-links

REPAIR DATABASE --fix-ridbags

REPAIR DATABASE --fix-bonsai

DISCONNECT

 执行完成后，尝试重启系统，查看nexus服务是否正常启动
