Permission denied when accessing new EBS volume

I'm new to AWS and EC2.

I just added a new EBS volume to my EC2 instance. I formatted and mounted it using instructions from another SO answer.

When I try to access the new volume I have permissions issues. cd /vol gives me 

-bash: cd: /vol: Permission denied

Does anyone know why I can't cd into the new volume?

In case it's relevant, ls -l /vol gives me

ls: cannot access /data/lost+found: Permission denied
total 0
d????????? ? ? ? ?            ? lost+found

. sudo ls -l /vol returns

 total 16
 drwx------ 2 root root 16384 Sep 12 22:14 lost+found

What am I doing wrong?

you need to change owner of the EBS volume.

Say you mounted the new EBS volume to xvdf_mountpoint folder. first run whoami to get your account name then switch to root: su root type in the password. if password not set: https://aws.amazon.com/premiumsupport/knowledge-center/set-change-root-linux/ chown [account name] /dev/xvdf then su [account name] ,then you have complete access to the newly mounted EBS volume.

you need to have rights to access the volume.

You may also take ownership of the volume, by doing in the console:

sudo chown `whoami` /vol

you may also change the rights with chmod. You may check documentation on chown and chmod linux commands.
