AWS EFS /etc/fstab

by Ulysses · Dec 23, 2019

To automatically mount a EFS volume after each reboot, you’ll need to add the following format to /etc/fstab.

You can use the DNS name given by AWS.

fs-12345678:/ /mnt/efs efs defaults,_netdev 0 0

Or the IP address.

10.0.0.22:/ /mnt/efs efs defaults,_netdev 0 0

Mount all with fake and verbose.

mount -fav

NFS Client

by Ulysses · Jun 10, 2019

Services to check.

chkconfig nfs on
service rpcbind start
service nfs start
mount -a

If missing, install it.

yum install nfs-utils nfs-utils-lib

Mount it.

mount -a
mount 192.168.1.200:/home /mnt/nfs/home

Add to /etc/fstab.

10.10.10.10:/home on /mnt/nfs/home type nfs (rw,noatime,nolock,bg,nfsvers=2,intr,tcp,actimeo=1800,addr=10.10.10.10)

The /etc/fstab file allow volumes to be automatically mounted on bootup. Add nofail in your automated mounts to prevent instances from hanging on boot. Nofail makes the instance to boot even if there are errors with the mounted volume.
