通过Amazon EBS 多重挂载,您可以将单个预置 IOPS SSD(io1或io2)卷挂载到位于同一可用区中的多个实例。您可以将多个启用多重挂载的卷附加到一个实例或一组实例。卷附加到的每个实例都对共享卷拥有完全读取和写入权限。通过多重挂载,您可以更轻松地在管理并发写入操作的应用程序中实现更高的应用程序可用性。
Before you can use your volume, you must attach it to one or more Amazon EC2 instances that are in the same Availability Zone as the volume. You can attach multiple volumes to an instance. If needed, you can detach a volume from one instance and then attach it to another instance. If...

@gnufiedI tried setting the--volume-attach-limitargument in a test environment and it worked fine. The only limitation that I find is that it applies to the entire cluster, if I have nodes, the other types of instances in AWS could limit the number of volumes that I can host, increasin...
In a traditional setup, if you want to add a disk to legacy systems, you need to purchase, find the hardware vendor, and insert it, which is a lengthy procedure. With Amazon EBS, if you want to add an additional disk to an EC2 instance, you can simply attach an EBS volume by click...
