Description of my issue

Hello and thanks for sharing your time!

I’am trying to mount my external USB3-HDD with an NTFS partition, for permanent use (Media-Files for Jellyfin).
My libreelec installation on another SD Card is able to mount it.

This is what I tried.

$ sudo mount /dev/sda2 /media/NAS1
Mount is denied because the NTFS volume is already exclusively opened.
The volume may be already mounted, or another software may use it which
could be identified for example by the help of the 'fuser' command.

$ fuser -m /dev/sda2 (Does nothing)

$ mkdir /media/NAS1
mkdir: cannot create directory ‘/media/NAS1’: File exists

 $ sudo blkid -o list -w /dev/null

I am absolutely not an expert, nd have not used an NTFS partition for years, but in what I understood, this is a Microsofs specific partition format and if you want to use this disk exclusively on your server, you should avoid it.
Something else I noticed when I had a multiboot is that Windows do not close the partitions which then become unusable for linux at all (until you manage to tell Windows to close them on shutdown).

But if you want to use this disk exclusively on your server, use a Linux compatible partition system.

I want to be able to move Files from my Windows Computers over SMB, that’s why I’m using NTFS.
Linux Filesystems won’t work with Windows on the fly.

EDIT: I heard from the HD shutdown problem too and plugged the HDD on my Windows Notebook and did a safe unplug/shutdown. But it changed nothing afaik.

Hi
try to install this package ntfs-3g
you need to create a directory on the Raspberry Pi (Debian) that will act as the mount point for the USB Hard Drive. To keep it organised, we will create this in the directory mnt and we will call the folder usbhdd to keep it simple.
follow this wiki

Thanks for your advice!
I did the tutorial step by step but getting the same error with mount -a:

Mount is denied because the NTFS volume is already exclusively opened.
The volume may be already mounted, or another software may use it which
could be identified for example by the help of the 'fuser' command.

My HDD/Partition is 4TB in size and uses GPT.
Could this be a problem?

What gives
mount - l
And

Try

sudo umount /media/NAS1

Then

sudo mount /dev/sda2 /media/NAS1
