我在 Windows 10 上的 Ubuntu Linux 子系统中的 docker 容器中运行 oracle DB oracle/database 18.4.0-xe。我想在本地保存我的数据文件，这样当我停止容器时就不会丢失数据。我使用下面的 docker 命令。
docker run -d -it --rm --name oracleXe -p 1521:1521 -p 5500:5500 -e ORACLE_PWD="Password1_One" -v /home/user/opt/oracle:/opt/oracle/oradata oracle/database:18.4.0-xe
当我查看 docker 日志时，出现以下错误
[FATAL] [DBT-06604] The location specified for 'Data Files Location' has insufficient free space.
CAUSE: Only (999MB) free space is available on the location (/opt/oracle/oradata/XE).
ACTION: Choose a 'Data Files Location' that has enough space (minimum of (3,609MB)) or free up space on the specified location.
Database configuration failed. Check logs under '/opt/oracle/cfgtoollogs/dbca'.

数据文件位置在哪里？999MB 的限制从何而来。我该如何增加它？如果我省略 -v，那么容器可以正常启动，当然无需在本地保留数据。
谢谢
