Permission denied when accessing new EBS volume

Question

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?

Solution 1

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.

Solution 2

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.
