由于磁盘空间不足，Nexus 删除快照时出错

Question

它无法部署较新版本的部署，并出现以下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project finances-web: Failed to retrieve remote metadata com.finances.web:2.1.7-SNAPSHOT/maven-metadata.xml: Could not transfer metadata com.finances.web:2.1.7-SNAPSHOT/maven-metadata.xml from/to isban (http://nexus3:8081/nexus/repository/maven-snapshots/): Failed to transfer file: http://nexus3:8081/nexus/repository/maven-snapshots/com/finances/web/2.1.7-SNAPSHOT/maven-metadata.xml. Return code is: 500 , ReasonPhrase:javax.servlet.ServletException: com.orientechnologies.orient.core.exception.OLowDiskSpaceException: Error occurred while executing a write operation to database 'component' due to limited free space on the disk (241 MB). The database is now working in read-only mode. Please close the database (or stop OrientDB), make room on your hard drive and then reopen the database. The minimal required space is 256 MB. Required space is now set to 256MB (you can change it by setting parameter storage.diskCache.diskFreeSpaceLimit) .?? DB name="component". -> [Help 1]

我尝试删除一些文件，以获得一些可用空间，但是我收到此错误（在 nexus Web 应用程序上）：

Error occurred while executing a write operation to database 'component' due to limited free space on the disk (1 MB). The database is now working in read-only mode. Please close the database (or stop OrientDB), make room on your hard drive and then reopen the database. The minimal required space is 256 MB. Required space is now set to 256MB (you can change it by setting parameter storage.diskCache.diskFreeSpaceLimit) . DB name="component"

我无法增加空间，因为它是附加到 Docker 映像的外部卷。

我能做些什么？
