# check if it has a file system
sudo file -s /dev/xvdf
# ...likely not, in which case you get:
#> /dev/xvdf: data
# if no file system, then create it
sudo mkfs -t ext4 /dev/xvdf
# mount it
sudo mount /dev/xvdf /home/ubuntu/ebs_tmp/
# change perm
sudo chmod 777 ~/ebs_tmp/
# to unmount
sudo umount /home/ubuntu/ebs_tmp
