PostPosted: Wed Aug 20, 2014 9:15 pm    Post subject: (Solved) How to mount seperate partition as non-root Reply with quote

So I made a partition with the filesystem NTFS while I was on Windows with my data.
I want to mount it so I can modify it and stuff.
But I can't mount it without root-privileges.
And when I am root, I can't modify any of the contents inside it.
How can I mount it as root and modify the contents inside it?
I also don't know how to tar archive a folder inside the partition since its not in root /.

It's my /etc/fstab entry for ntfs partition:
Code:
/dev/sda5      /mnt/STORAGE      ntfs   defaults   0 0

It mounts partition at boot and I can modify a content as regular user.
Depending on your system settings, it may require some additional options, e.g.:
Code:
/dev/sda5      /mnt/STORAGE      ntfs   defaults,users,umask=000   0 0

user should be in users group.

To mount a partition not at boot time you can use the following:
Code:
ntfs-3g /dev/sda5 /mnt/STORAGE -o users,umask=000

What I meant for that was,
I've learned to tar stuff inside /dev/sda3 (my root)
but how can I tar something thats in /dev/sdb or /dev/sda4
since / is /dev/sda. How do I indicate in the terminal that I'm no longer in /dev/sda3 but in /dev/sda4?

you don't access partitions, you access its mount point.

in creaker example, it mounts the /dev/sda5 at /mnt/STORAGE so to be on it, it's as easy as typing "cd /mnt/STORAGE"

And you do not need to be in users group to mount it as a user. See man 8 mount.

Okay. I am able to mount my partition now. But I still can't access it as non-root.
Code:
$ cd /mnt/STORAGE
bash: cd: /mnt/STORAGE: Permission denied

Also, while I'm as root, I can't modify any of the contents inside it.
it says:
Code:
# cd /mnt/STORAGE
# cp file_name.txt modified_file_name.txt
cp: cannot create regular file 'modified_file_name.txt': Permission denied

I created this partition using Windows 7 (ntfs), so does that factor into anything?
I built my kernel with ntfs support:
Code:
File systems --->
    DOS/FAT/NT Filesystems --->
       <*> MSDOS fs support
       <*> VFAT (Windows-95) fs support
       (437) Default codepage for FAT
       (iso8859-1) Default iocharset for FAT
       <*> NTFS file system support
       [    ] NTFS debugging support
       [ * ] NTFS write support

ShanaXXII,

Ahhh.
Code:
[ * ] NTFS write support
doesn't do what you think it does.

NTFS write support in the kernel was always unsafe. Its been made safe by restricting it to changing the content of an existing file, provided the file size does not change.

You need FUSE support in your kernel and emerge ntfs-3g
The filesystem type will be ntfs3g

You can leave ntfs in the kernel if you like as long as you net ntfs3g for the filesystem type when you mount your ntfs volumes.

you can mount those with ntfs-3g or use the regular mount command with the user flag (check for that user flag, it means any user can use that drive). also the mount point needs to be owned by that user. when teh permissions of the mount point are wrong you are unable to use it also. i usually mount it to the user created folder such drives as root.

Okay. I think I almost got it working.
I emerged ntfs-3g with "-external-fuse suid"
I can now mount/read/write with root. I can read/write with user now, but I still can't mount with user (kind of a bummer).
It gives me an error saying:
Code:
Error opening '/dev/sda4' : Permission denied
Failed to mount '/dev/sda4': Permission denied
Please check '/dev/sda4' and the ntfs-3g binary permissions, and the mounting user ID. More explanation is provided at http://www.tuxera.com/community/ntfs-3g-faq/#unprivileged

So I went on the site and it said to make sure the user has permission access to both the volume and the mount point.
I know my user has access to the mount point. I'm pretty sure it has access to the volume too, since I am able to write in it.

I guess I can live with this, but I still kind want to be able to mount it as a user. :(

Please have a look at

Code:
https://wiki.archlinux.org/index.php/fstab


Quote:
The user flag means that any user (even non-root) can mount and unmount the partition /dev/sdX. rw gives read-write access; umask option removes selected rights - for example umask=111 remove executable rights. The problem is that this entry removes executable rights from directories too, so we must correct it by dmask=000. See also Umask.


There is someway to use the mount command with the user flag, not sure about invocation now, but man mount should give you the details:

I can not test such things at the moment as I do not have any external drives anymore ...

Code:
mount user-flag ....
You should be able to find it on the net with this explanation or check man mount please ...


one of the first results on a popular internet search engine:

I read the mount man page and changed some stuff around.
Before it gave me:
Code:
$ mount /dev/sda4
Error opening '/dev/sda4' : Permission denied
Failed to mount '/dev/sda4': Permission denied
Please check '/dev/sda4' and the ntfs-3g binary permissions, and the mounting user ID. More explanation is provided at http://www.tuxera.com/community/ntfs-3g-faq/#unprivileged

Now its giving me:
Code:
$ mount /dev/sda4
mount: only root can mount /dev/sda4 on /mnt/storage


Whats going on now?

ShanaXXII,

Please post your /etc/fstab and the output of
Code:
ls -l /mnt
when nothing is mounted on /mnt/storage

ShanaXXII,

There are two issues.

Code:
$ ls -l /mnt
shows that /mnt/storage does not exist so your fstab line
Code:
/dev/sda4      /mnt/storage   ntfs      noauto,shana,suid   0 0
will not work. shana is not a valid option for the mount command.

You need to use user or users.
user allows any non root user to use the lazy form of mount, either mount /dev/sda4 or mount /mnt/storage, but only the same user that gave the mount command can use umount.
With an optical drive, the tray is locked.

users allows any non root user to use the lazy form of mount and any non root user to use the lazy form of umount.


A detail, ntfs will use the kernel ntfs driver. You probably want ntfs3g here

A detail? I changed the <type> in my fstab from ntfs to ntfs3g:
Code:
$ mount /dev/sda4
mount: unknown filesystem type 'ntfs3g'

And sorry, I was using /mnt/storage because the other guy from before (creaker) was using it in his example.

ShanaXXII,

When mount fails, it often leaves a message at the end of the kernel log.
In a terminal, type the command
Code:
dmesg
to see it all,
Code:
dmesg | less
to scroll through it all and
Code:
dmesg | tail
to see the end.

Homework. What does the command
Code:
dmesg | tail -n 30
do ?

ShanaXXII,

Yep you got your homework right - well done.

Code:
$ mount /dev/sda4
Error opening '/dev/sda4': Permission denied
Failed to mount '/dev/sda4': Permission denied
Please check '/dev/sda4' and the ntfs-3g binary permissions,
and the mounting user ID. More explanation is provided at
http://tuxera.com/community/ntfs-3g-faq/#unpriviledged


That link in the last line may be useful.

I can't test as I gave up Windows in 2002.
