[RESOLVED] ext4 3TB = 2.73 or 2.68TB?

Hello

I have OpenMediaVault amd64 installed on 64gb SSD and at the moment one 3TB WD Green disk as storage.
I have formated it as ext4 but I want to be sure everything is okey since it's only showing me 2.68TB as total space,
while formated as NTFS in a Windows computer shows me 2.73TB.

Under Physical Disks it shows me 2.73TB, but:
under Filesystems it shows me 2.68TB and also when shared, the client sees 2.68TB as well.

How can I fix it? Already done "sudo tune2fs -m 0 /dev/sdXX" to clear the reserved space.

Also I booted with Ubuntu Live and made a partition on the SSD to also use as some storage space since the OS don't require much space
and I was wondering if that is a correct way to do it?

Thanks in advance!

2.73 is the size of the disk. Formatting a drive uses some space. That is why you only have 2.68 TB in Filesystems. No way around that.

And yes, as long as you didn't make the OS partition too small, that will work adding the partition.

Thanks for quick response

On the topic just for curiosity, do you know why NTFS shows 2.73 and ext4 shows 2.68?

make sense, thanks for quick and good response!
now I can continue with my setup.
