go to ec2 instance terminal
lsblk
As you can see there is only 1 volume at this point, now lets attach the new one
status is now in-use
lsblk
Now we have 2. Now lets mount. Lets make a directory. “/werm”
mkdir /werm
though in our terminal it shows up as xvdf1, we need to actually use this value
mount /dev/sdf1 /werm
to unmount
umount -d /dev/sdf1
to ensure mounting on restart edit /etc/fstab
