Wrong disk size reported in settings. Only visual?

Hannes1 · October 30, 2020, 1:58pm

Hey, I’ve attached a 12TB drive to my nc Raspberry Pi, which in the nc settings page only reports as a 2TB Disk.

fdisk -l shows

Device     Start         End     Sectors  Size Type
/dev/sdb1   2048 23437694383 23437692336 10.9T Linux filesystem

However the Settings Panel shows me a maximum of TB free space, the Size of the Disk grows as it gets fuller. What is the issue here?

Thanks in advance

check out the size with df -h. This tool probably doesn’t know that you can grow the disk.

			$result[] = $iface;
		}

		return $result;
	}

	public function getDiskInfo(): array {
		$data = [];

		try {
			$disks = $this->executeCommand('df -TPk');
		} catch (\RuntimeException $e) {
			return $data;
		}

		$matches = [];
		$pattern = '/^(?<Filesystem>[\S]+)\s*(?<Type>\w+)\s*(?<Blocks>\d+)\s*(?<Used>\d+)\s*(?<Available>\d+)\s*(?<Capacity>\d+%)\s*(?<Mounted>[\w\/-]+)$/m';

		$result = preg_match_all($pattern, $disks, $matches);
		if ($result === 0 || $result === false) {
			return $data;

If you wanted me to implement it: No disk size whatsoever will show up

you can also search the internet for “linux fdisk 2tb limit”. Sounds like you have used the “wrong” partion table to create a new partion.

So I guess there is no way without formating again?

Don’t format the disk again and save your time

If fdisk -l shows and/or df -TPk shows the right value it’s a bug in Nextcloud’s serverinfo app.
