EFS is somehow being unmounted from ec2 linux servers after some time

Question

I currently have a EFS mount to 2 linux servers. Randomly after weeks one of them would randomly get unmounted. I have been trying to do some research as to why this would happen. Are there any logs or any general issues with EFS that this could pertain to? This is the command I use to mount the EFS:

sudo mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2 fs-xxxxxxx.efs.us-west-2.amazonaws.com:/ /var/lib/emapi/static

Any help would be much appreciated.

Thanks!

Answer 1

Have you added the volume to /etc/fstab ?

Its likely being lost when the instance reboots.
