Mount and Unmount EFS

Here’s the command to mount and unmount AWS EFS. Assuming the EFS IP address is 10.0.0.23.

Mount:

mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport 10.0.0.23:/ /efs

Umount:

# lazy unmount
umount -l /efs
# force unmount
umount -f /efs

You may have to force it if it’s busy.
