部署新版本的部署失败，但出现以下错误：

我试图删除一些文件，以获得一些可用空间，但是我得到了这个错误（在nexus网络应用程序上）：
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，因为它是附加到泊坞窗图像的外部卷。
我该怎么办？
