Mount an EFS file system via NFS on AWS

On target system, install prerequisites:

apt install nfs-common

Create EFS file system in the same region.

Add to /etc/fstab and replace the values:

availability_zone.file_system_id.efs.region.amazonaws.com:/ /mnt nfs4 nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport,_netdev 0 0

Mount:

mount /mnt/ -v

Check:

df -ha|grep /mnt

Typical output:

eu-north-1a.fs-xxxxxxxxxxxxx.efs.eu-north-1.amazonaws.com:/  8.0E     0  8.0E   0% /mnt
