这是具体报错信息，能否重新执行root.sh脚本呢

先查$GRID_HOME/log/主机名/下面的日志具体报错原因，直接重新运行root.sh是没用的

有一个alert日志下有以下信息：没太看明白

在安装的时候默认会选择AFD，建议取消勾选。

那个也没有勾选过，我是在4G的虚机内存，不知道会不会因为内存太小的缘故。

4G内存够了，AFD会默认勾选，要手工取消

重头检查了一遍，AFD是我手动取消的，跑root.sh到第18步,报了相同的错误，网上和mos也都没查到，能看出是哪的问题吗？
错误如下：

解决了没，dd磁盘重新运行试试。

问题应该是我虚拟机内存太小缘故，换其他环境是没有问题的。
