Both of these methods use the EFS mount helper to mount the file system. The mount helper is part of the amazon-efs-utils set of tools. For more information about amazon-efs-utilssee Using the amazon-efs-utils Tools. The EC2 instance mounts the file system automatically the instance first launched and also whenever it restarts. Before you perform this procedure, make sure that you have created your Amazon EFS file system.

Before you can launch and connect to an Amazon EC2 instance, you need to create a key pair, unless you already have one. If you already have a key pair, you can use it for this exercise. For Subnetchoose a default subnet in any Availability Zone.

For File systemschoose the EFS file system that you want to mount. The path shown next the file system ID is the mount point that the EC2 instance will use, which you can change.

Choose Add to user data to mount the file system when the EC2 is launched. Under Advanced Detailsconfirm that the user data is present in User data. Name your instance and choose Next: Configure Security Group.

Choose the default security group to make sure that it can access your EFS file system. You can use the following settings:. Select the check box for the key pair that you created, and then choose Launch Instances.If you've got a moment, please tell us what we did right so we can do more of it.

Why is my Linux instance not booting after I changed its type to a Nitro-based instance type?

We're sorry we let you down. If you've got a moment, please tell us how we can make the documentation better. Following, you can find information about troubleshooting file-system mounting issues for Amazon EFS. This issue can occur if your NFS client does not have permission to mount the file system. If you are attempting to mount the file system using IAM, make sure you are using the -o iam option in your mount command.

If you still don't have access, check your file system policy and your identity policy to ensure there are no DENY clauses that apply to your connection, and that there is at least one ALLOW clause that applies to the connection. This result is because network file systems need to be initialized after the compute instance starts its networking. In this case, the dmesg output shows one or more lines similar to the following.

Then restart your Amazon EC2 instance.

How to Attach and Mount an EBS volume to EC2 Linux Instance

The file systems are mounted on demand, generally within a second. If you receive this message, install the nfs-utils or nfs-common on Ubuntu package.

This error message most likely means that your Linux distribution doesn't support Network File System versions 4. To confirm this is the case, you can run the following command. If you're programmatically creating and mounting file systems, for example with an AWS CloudFormation template, we recommend that you implement a wait condition.

The file system mount command hangs for a minute or two, and then fails with a timeout error. The following code shows an example. This error can occur because either the Amazon EC2 instance or the mount target security groups are not configured properly. Make sure that the mount target security group has an inbound rule that allows NFS access from the EC2 security group.

For more information, see Creating Security Groups. Verify that the mount target IP address that you specified is valid. If you specify the wrong IP address and there is nothing else at that IP address to reject the mount, you might experience this issue.

A file system mount that is using a DNS name fails. Check your VPC configuration. To specify a DNS name in the mount command, you must do the following:. Use the noresvport mount option to make sure that the NFS client uses a new TCP source port when a network connection is reestablished.

Doing this helps ensure uninterrupted availability after a network recovery event. The mount target lifecycle state is stuck in the creating or deleting state. An Amazon EFS mount appears unresponsive. For example, commands like ls hang. This error can occur if another application is writing large amounts of data to the file system. Access to the files that are being written might be blocked until the operation is complete. In general, any commands or applications that attempt to access files that are being written to might appear to hang.

For example, the ls command might hang when it gets to the file that is being written. This result is because some Linux distributions alias the ls command so that it retrieves file attributes in addition to listing the directory contents. To resolve this issue, verify that another application is writing files to the Amazon EFS mount, and that it is in the Uninterruptible sleep D state, as in the following example:.It is built to scale on demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files, eliminating the need to provision and manage capacity to accommodate growth.

By simply enabling EFS Lifecycle Management on your file system, files not accessed according to the lifecycle policy you choose will be automatically and transparently moved into EFS IA. Amazon EFS transparently serves files from both storage classes in a common file system namespace.

Step 6: Format the volume to the ext4 filesystem using the following command. Step 7: Create a directory of your choice to mount our new ext4 volume. You can add more than one EBS volumes to an ec2 instance as an additional disk. You can follow the same steps explained above and the only difference will be the disk name that you get from the lsblk command.

You can attach a maximum of 20 EBS volumes to the instance. However, limit the maximum volumes to have optimal performance. Also, plan your instance capacity based on the workload you are trying to run. For example, databases require high IOPS for high read-write rates.

IOPS depends on the disk size. Higher the size, the higher the IOPS. If you get any error during the setup, please feel free to contact us in the comment section.

Thanks for letting us know this page needs work. We're sorry we let you down. If you've got a moment, please tell us how we can make the documentation better. 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. You can take snapshots of your EBS volume for backup purposes or to use as a baseline when you create another volume.

Use the following procedure to make the newly attached volume available for use. Connect to your instance using SSH. For more information, see Connect to Your Linux Instance.

aws fstab

The device could be attached to the instance with a different device name than you specified in the block device mapping. For more information, see Device Naming on Linux Instances. Use the lsblk command to view your available disk devices and their mount points if applicable to help you determine the correct device name to use. The following is example output for a T2 instance. Determine whether there is a file system on the volume.

New volumes are raw block devices, and you must create a file system on them before you can mount and use them. Volumes that have been restored from snapshots likely have a file system on them already; if you create a new file system on top of an existing file system, the operation overwrites your data.

aws fstab

Use the file -s command to get information about a device, such as its file system type. If the output shows simply dataas in the following example output, there is no file system on the device and you must create one. If the device has a file system, the command shows information about the file system type.

For example, the following output shows a root device with the XFS file system. Conditional If you discovered that there is a file system on the device in the previous step, skip this step.

If you have an empty volume, use the mkfs -t command to create a file system on the volume. Do not use this command if you're mounting a volume that already has data on it for example, a volume that was restored from a snapshot. Otherwise, you'll format the volume and delete the existing data. If you get an error that mkfs. Use the mkdir command to create a mount point directory for the volume.

The mount point is where the volume is located in the file system tree and where you read and write files to after you mount the volume.
