Locked out of drive on Ubuntu Server

[<<Onafets>>]

Hey guys,
I was trying to delete some torrents that I had downloaded with transmission-daemon and was unable to from my samba share on windows. I figured the best solution was to 'sudo chmod -R 0777 /media/Storage' (my drive with samba) but apparently not.
This locked both my windows user and my user on my ubuntu server out of the drive completely with a message saying 'ls: cannot access /media/Storage: Permission denied'.
I am able to login as root with 'sudo bash' and make changes however I am uncertain as to how to make my drive accessible again.
Doing a 'ls -ld' on the directory shows 'drwsrwsrwx 39 root root 4096 Nov 17 21:20 /media/Storage'
Any ideas?

try chowning it first:

sudo chown -R [username]:[group] /to/some/path

Then try granting user permissions.

sudo chmod -R u+rw /to/some/path

sudo chown -R [username]:[group] /to/some/path

Then try granting user permissions.

sudo chmod -R u+rw /to/some/path

Both commands executed without errors however I am still unable to access/ls the directory from either Windows or Ubuntu. Still getting the same 'ls: cannot access /media/Storage: Permission denied' message.

Stop trying to access it in Windows until you can actually get into it in Linux.

Is the drive even mounted?

How does the output of

sudo mount

look?

sudo mount dumps

/dev/sdb1 on / type ext4 (rw,errors=remount-ro)

/dev/sda1 on /media/Storage type ext4 (rw) is the drive

So after you chmod and chown the directory, what does "ls -l /media/" show?

Preferably a before and after would be nice.

before

sudo ls -la /media/Storage
drwsrwsrwx 39 root root 4096 Nov 17 21:20 /media/Storage

after

ls -l /media
ls: cannot access /media/cdrom: Permission denied
ls: cannot access /media/Storage: Permission denied
total 0
d????????? ? ? ? ?            ? cdrom

sudo ls -l

Hmmm, and you can't access it now? I'm assuming "onafets" is your account.

When you restart are the permissions the same?

These are the permissions that I have on my workstation for /media

maybe

sudo chown -R root:root /media
sudo chmod -R 775 /media

Restart before you try anything else then tell me how it works. Also are you mounting the drive or is Ubuntu doing it for you?

 

[<<Onafets>>]

sudo chmod -R 775 /media

Allows me to access the drive and its contents however I ended up modifying it to 777 so I was able to delete my files. Thank you!

You're welcome but make sure you're setting the right permissions to the right directory.

sudo chown root:root /media
sudo chmod 775 /media
sudo chmod -R 777 /media/Storage

Just make sure /media itself belongs to root and is chmod'ed to 775, even if Storage is 777.
