我创建了一个公共VPC，然后添加了一堆节点给它，这样我可以使用它的火花集群。不幸的是，他们都有一个分区设置，看起来像下面这样：

I created a public VPC and then added a bunch of nodes to it so that I can use it for a spark cluster. Unfortunately, all of them have a partition setup that looks like the following:

ec2-user@sparkslave1: lsblk
/dev/xvda 100G
/dev/xvda1 5.7G /

我安装在这些机器顶部的云管理器，所有的节​​点只有1G留给HDFS。如何扩展的分区，这样，它占用了所有的100G的？

I setup a cloud manager on top of these machines and all of the nodes only have 1G left for HDFS. How do I extend the partition so that it takes up all of the 100G?

我试图创建的/ dev / xvda2，然后创建一个卷组，添加了所有的/ dev / xvda *到它，但为/ dev / xvda1没有得到补充，因为它的安装。我无法从现场CD在这种情况下启动，这是在AWS上。我也试过resize2fs中，但它说，根分区已经占用了所有的可用块，所以它不能被调整。我该如何解决这个问题？如何避免以后发生这种问题呢？

I tried created /dev/xvda2, then created a volume group, added all of /dev/xvda* to it but /dev/xvda1 doesn't get added as it's mounted. I cannot boot from a live CD in this case, it's on AWS. I also tried resize2fs but it says that the root partition already takes up all of the available blocks, so it cannot be resized. How do I solve this problem and how do I avoid this problem in the future?

谢谢！

我不认为你可以调整正在运行的根卷。这是你如何去增加根大小：

I don't think you can just resize the running root volume. This is how you'd go about increasing the root size:
