Problems mounting ntfs drive

Johantonissen · 03-27-2020, 01:15 PM

Hello there,

I have some problems punting my ntfs drives.

I’ve mounted my drives as the following which works fine except i cant change the user and group of my files and folders. It does mount my drive and allows me to create files on the new drive, i just don’t have permission to change files weirdly enough.

This is done with the following permissions:

Code:

cat /etc/fstab
UUID=e9fb6ad8-1bc1-4c64-aef4-401780935e3e / ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro 0 1
tmpfs /tmp tmpfs defaults,nosuid 0 0
UUID=B0561F00561EC74E /media/kist ntfs-3g defaults 0 0

I however want to be able to be able to change folders owners and groups so I’ve checked how i can change the permissions in order to do that. Ive found the following link:
https://unix.stackexchange.com/quest...-to-mount-ntfs

This way I’ve set the following permissions:

Code:

cat /etc/fstab
UUID=e9fb6ad8-1bc1-4c64-aef4-401780935e3e / ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro 0 1
tmpfs /tmp tmpfs defaults,nosuid 0 0
UUID=B0561F00561EC74E /media/kist ntfs-3g rw,auto,user,fmask=133,dmask=022,uid=1000,gid=1000 0 0

However when i apply that nu drive doesn’t mount correctly and i get an unstable system.
I can’t even access the system over ssh anymore. And when i click the drive the system crashes.

Does anyone have an idea how i can solve this ? Or where the problem lies in this what i’m doing ?

I’m running armbian system with Ubuntu bionic.

I can unfortunately not change the drive from ntfs to ext4 since the drive is 4TB and I don’t have such a large drive around to make the backup.....

Thank you in advance.

I may be wrong but I don't think it is possible to change permissions of an NTFS drive from Linux. I don't have windows or use NTFS at all so someone that has a set up similar to yours may be able to clarify.

As above, NTFS is a Microsoft file system, you can only change permissions with a Microsoft system, (from memory), they are completely different from Linux permissions.

(Your fstab line allows a user to mount it.)

And to add to fatmac's post: the ntfs-3g package allows Linux to mount, read and write to the NTFS file system but as mentioned, permissions can't be changed.

You can make all files and directories one userid/groupid, with the uid= and gid= options on the mount, but as those uid/gid's are faked BY the driver (the ntfs file system doesn't have a user and/or group field value) you cannot change them, the driver will accept but ignore the command to do so.
So all files and directories on a vfat or ntfs system are always one and the same value for owner and group.
By playing with the fmask and dmask (although I'm not quite sure they're accepted by the ntfs-3g driver) options, you may be able to change the default permission mask, but:

Code:

uid=value, gid=value and umask=value
          Set the file permission on the filesystem.  The umask value is given in octal.
          By default, the files are owned by root and not readable by somebody else.

(from man mount, for the ntfs entry).

Note that THIS man page doesn't mention fmask (umask for files only) or dmask (directories only), which are supported for vfat. But ntfs-3g may be different.

Hi all, I’ve decides to format the drive to ext4 for 50% and move the files over. The ntfs-3g drivers seems to cause to much problems and flags don’t deem to be working correctly. I’d figure its better to install an ext4 driver on windows then have a windows compatible disk on linux since i use it for linux like 99,9% of the time.

And jefro, thanx for the comment but please stay to programming and don’t try to have a opinion to something you clearly don’t have an clue about. Programmers can have opinions about programming, I’m a renewable energy professor and can have a opinion about renewable energy. Please listen to healthcare professions and obey their opinions, they know more about it than you they have a valid opinion while yours is based on opinion. You sound like a anti-van mom. Please don’t spread false information, ever.
