USB External disk - Half space missing

pascalbressan · June 4, 2021, 5:31pm

Hi everyone,
my name is Pascal and I’m a newbee in linux world.

I experiencing this frustrating problem with my external usb disk.

I’m using an old mac book pro as a media server, i installed Opensuse 15.2 Leap (5.3.18-lp152.75-default).

The Usb external disk is this:

Disk /dev/sdc: 10,9 TiB, 12000105070592 bytes, 23437705216 sectors
Disk model: Elements 25A3
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 354B3DB5-C553-415D-A012-34BAAD34F5CC

Dispositivo Start Fine Settori Size Tipo
/dev/sdc1 40 409639 409600 200M EFI System
/dev/sdc2 411648 23437703167 23437291520 10,9T Microsoft basic data

I mounted /dev/sdc2 in the directory /Plex Media

The actual utilization is this:

pascal@localhost:/> du -hs /Plex\ Media/
5,5T /Plex Media/

The disk free command report this:

File system Dim. Usati Dispon. Uso% Montato su
/dev/sdc2 5,5T 5,5T 27G 100% /Plex Media

I really dont understand, half disk is missing, the sdc2 is 10T but at 5,5T it’s give me only 27G left!

Can someone help me??

Thanks!!

Please, next time, include the command together with the output. Only one line more at the begin to copy! As @Sauerland showed. No need to type: “The disk free command report this:” because we will see what you did.

hcvv · June 4, 2021, 7:54pm

Because you mounted it, there must be a file system on that partition. What is the file system type? Please show (as root)

lsblk -f

Sauerland · June 4, 2021, 8:21pm

Do you shutdown your Windows; no fast boot?

There is an option in windows to start windows faster, is this option off?

Please post:

zypper se -si ntfs fuse

Regarding the size mismatch:

According to fdisk it is indeed 10.9T and disk usage (du) says the disk is about 55% full:

/dev/sdc2  411648 23437703167 23437291520 10.9T Microsoft basic data
pascal@localhost:/> du -hs /Plex\ Media/
5,5T /Plex Media/

That looks fine, where things go wrong are with “df” and “lsblk -f”

I think that has to do with ntfs.

Can you check if there are any ntfs messages in the jorunal:

sudo journalctl -b -g ntfs

Please post the output (removing unwanted entries) here using CODE tags.

Also would be good to try either Tumbleweed or 15.3. No need to install it, just boot from USB and get it a try there, it might be this problem is solved in later releases.

Ah, it is an NTFS file system. That is not Linux, thus I am not qualified to comment on what it is able to do (maybe there is a size restriction?).

pascalbressan · June 5, 2021, 10:57am

It’s an 2010 Mac Book Pro, no OS X o Win installed, only OpenSuse.

There is any possibility to convert the file system without losing the data?

hcvv · June 5, 2021, 11:17am

Only by saving the files elsewhere and later copying back. IMHO one should only use non-Linux file systems on Linux for exchange of files between Linux and a non-Linux file system. For the rest it should be avoided.

(And as you experienced, others are so bound to this idea that they assume that you use it for exchange with Windows without even asking you if there is any Windows involved).

there is no -g option in jurnalctl, here -b option:

pascal@localhost:~> sudo LANG=C journalctl -b ntfs
Failed to add match 'ntfs': Invalid argument

I’m downloading Tumbleweed

pascalbressan · June 5, 2021, 3:53pm

I used NTFS for better flexibity, now i know i did wrong

marel · June 6, 2021, 10:06am

Good luck trying Tumbleweed.

“journalctl -g” works for me in Tumbleweed but if it does not work in Leap, please try:

sudo LANG=C journalctl -b |  grep -i ntfs

This filters out all the ntfs message in your boot log.

In the end I decided to switch to ext4.

So I resized the NTFS partition to 6T with parted and i create a new 6T partition in ext4.

Now i’m coping files from NTFS to EXT4 partition with rsync (it will take days i know), after that i’ll remove NTFS partition ad resize the ext4 one.

Thanks all for support and understanding
