I created two virtual disks for AWS EC2. One is 16G and the other is 100G.
When I connect to EC2 with puTTy it does not show the disks that I created.
Anyone know what the problem is or how to fix it? Thanks.
Make an Amazon EBS volume available for use on Linux
After you attach an Amazon EBS volume to your instance, it is exposed as a block device. You can format the volume with any file system and then mount it. After you make the EBS volume available for use, you can access it in the same ways that you access any other volume. Any data written to this file system is written to the EBS volume and is transparent to applications using the device.
Depending on your requirement you can choose two ways:
Format and mount an attached volume
Automatically mount an
attached volume after reboot

I've looked at EFS and EBS Multi-Attach, but neither support Windows. I've looked at S3, but it's blob storage (I guess?), not a proper volume.
I just want a simple volume that I can mount from multiple instances. I realize I could just set up a share on one of the instances, but I'd prefer it not be instance-dependent (IE if I do scaling, etc).
Ideally I'd be able to access it as a mounted disk, but I'd also be fine with a mapped network drive.
Is there an AWS service that will do this?
I think you can mount an S3 bucket on ec2 instances.

We have a EBS volume from a previous T2 instance, which contains operating system, mysql installation, created users and all configurations.
For launching a new instance (T2), how to use
the pre-existing EBS volume as main bootable disk so that we have the operating system, apps and all configurations? This would save us days of time and efforts.
For a business application, should we choose T2 or T3?
As discussed you can perform the below steps to create an EC2 instance from a pre existing EBS volume.
Create a snapshot from the EBS volume.
Create an AMI from the same.
Look for the AMI in your private AMI.
Create the EC2 instance with desired instance-type from this AMI.
Also you need to care for the EBS volumes with this new EC2 instance with minimum EBS volume size etc.
Please let me know.
I am having a problem here in AWS Instance I already created the volume but when I check in the Remote Desktop it only shows the 100GB storage.

Attaching new volume to an instance is not enough to be able to use it. You have to format it for your operating system. For example, for linux:

Here is my problem:
Deleted attachments from an app we're using
Attempted a restore from backup but unfortunately the app was not set up to back up needed attachments
The app is hosted in AWS on an EBS-backed volume. I would like to attempt to create a volume from an earlier snapshot which contains the needed attachment files. The question is have is, ServerA is the prod server and ServerB is the staging server, both with completely different/unique FQDNs, if I were to mount the volume from ServerA into ServerB, would that cause any problems with ServerA?
I have tested the mounting method and i know it works. I can mount the volume and then from within the instance, I can mount the volume to a virtual device and then mount that virtual device to a mount point. From there, I can access the files and copy as needed. I just don't want to mess up anything on ServerA since it contains our prod application. Has anyone done this before? Will mounting an earlier snapshot of ServerA onto ServerB cause problems for the live version of ServerA??
Sorry for the confusing explanation.
An Amazon EBS volume can only be attached to one Amazon EC2 instance at a time.
If you have created a new EBS volume from an EBS snapshot, then it is a totally separate volume and may be attached to any instance (prod/non-prod, any VPC, etc) within that Availability Zone. (You nominate the AZ when creating the Volume from the Snapshot.)
No danger will result from mounting your 'restored' volume on any instance. It will not impact your production system. Just think of it like plugging a portable USB drive into a computer -- it will not impact any other drive.
[Eucalyptus]
I have a EBS volume created, and i will have to attach it to all other running instances. Currently AWS EBS volume attaches to only one running instances at a time.
So, Are there any other volume types which actually attaches one volume to multiple instances? Please help.
A Better approach would be to use AWS EFS. It's Network File Sharing on Steroids (provided by AWS, obviously). You can share a volume between multiple instances. AWS EFS - Elastic File System
Hope this helps.
No, you can not attach one EBS Volume to multiple instances at the same time in Eucalyptus. You can only attach to one instance, then detach the volume and attach to another instance.
