I'm fairly sure you can't, but you can clone an EBS and attach it to another instance.

This is useful for fixed datasets, or for testing on 'real' data but doesn't allow more than 1 instance to operate on a single block store

No, according to the EBS docs: "A volume can only be attached to one instance at a time". 

How are you using the shared storage currently? If it's just for serving files from the fileserver, have you considered setting up a system so that you could proxy certain requests to a process on the fileserver rather than having the webservers serve those files?

Multiple Web Servers accessing MySQL Server &amp; File Server is normal in AWS. Some of the best practices to be followed for the above mentioned architecture are:

Point 1) MySQL on EC2 can be setup as Master-Slave in async/semi sync mode in AWS. EBS-OPT+PIOPS in RAID 0 is recommended for High performance DB

Point 2) Alternatively you can use Amazon RDS + Multi-AZ mode. For read scaling Multiple RDS Read Replica's can be attached to MySQL RDS.

Point 3) EBS Volume cannot be attached to Multiple EC2's simultaneously. You can create File server based on GlusterFS on Amazon EC2 using EBS. Multiple Web Servers can talk to single GlusterFS simultaneously on AWS infra.

Point 4)In case your application can be integrated with S3 as file store, then it is preferred because of the stability it brings in to the architecture. You can also access S3 using tools like S3fuse as well from your application.

You can totally use one drive on multiple servers in AWS. 
I use sshfs to mount an external drive and share it with multiple servers in EC2. 

The reason I needed to connect a single drive to multiple servers is to have a single place to put all my backups before pulling them down local.

Although EBS has previously only allowed a single EC2 instance to be attached to a given volume, multi-attach is now possible, at least for io1 volumes.

We currently use multiple webservers accessing one mysql server and fileserver. Looking at moving to the cloud, can I use this same setup and attach the EBS to multiple machine instances or what's another solution?

Can you attach Amazon EBS to multiple instances?

文件存储

文件系统

数据库

服务器

MySQL

我们目前使用多个We服务器访问一个mysql服务器和文件服务器。看看迁移到云，我是否可以使用相同的设置并将EBS连接到多个机器实例，或者其他解决方案？
