EFS implementation

EFS implementation:

To install and mount the EFS service on instances:

Set up your EC2 instance:

• Open an SSH client and connect to your EC2 instance.

• If you're using an Amazon Linux EC2 instance, install the EFS mount helper with the following command:
  

  sudo yum install -y amazon-efs-utils
  You can still use the EFS mount helper if you're not using an Amazon Linux instance. [https://docs.aws.amazon.com/console/efs/efs-utils Learn more
  

  ]If you're not using the EFS mount helper, install the NFS client on your EC2 instance:

  • On a Red Hat Enterprise Linux or SUSE Linux instance, use this command:
    sudo yum install -y nfs-utils

  • On an Ubuntu instance, use this command:
    sudo apt-get install nfs-common

Mounting your file system:

1. Open an SSH client and connect to your EC2 instance.

2. Create a new directory on your EC2 instance, such as "efs".

   • sudo mkdir efs

3. Mount your file system with a method listed following. If you need encryption of data in transit, use the EFS mount helper and the TLS mount option. Mounting considerations

   • Using the EFS mount helper:
     sudo mount -t efs fs-641191b5:/ efs

   • Using the EFS mount helper and the TLS mount option:
     sudo mount -t efs -o tls fs-641191b5:/ efs

   • Using the NFS client:
     sudo mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport fs-641191b5.efs.ap-south-1.amazonaws.com:/ efs

fstab entry:

#sudo nano /etc/fstab
Add this blow command in the fstab file.
fs-641191b5.efs.ap-south-1.amazonaws.com:/ /efs nfs4 nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2 0 0

1. sudo umount /efs
   

#sudo mount -a
