Create a new directory and mount it to EBS volume:
$ cd / && mkdir ebs-data
$ mount /dev/xvdf /ebs-data/
Check volume mount:
$ df -h

In order to make it mount automatically after each reboot, we need to edit /etc/fstab, first make a backup:
$ cp /etc/fstab /etc/fstab.orig
Find the UUID for the volume you need to mount:
$ ls -al /dev/disk/by-uuid/
total 0
drwxr-xr-x. 2 root root 80 Nov 25 05:04 .
drwxr-xr-x. 4 root root 80 Nov 25 04:40 ..
lrwxrwxrwx. 1 root root 11 Nov 25 04:40 de4dfe96-23df-4bb9-ad5e-08472e7d1866 -> ../../xvda2
lrwxrwxrwx. 1 root root 10 Nov 25 05:04 e54af798-14df-419d-aeb7-bd1b4d583886 -> ../../xvdf
Then edit /etc/fstab:
$ vi /etc/fstab
with:

Check if fstab has any error:
$ mount -a
