Mounted Volume in a Container shows 100 % usage

Overview

We have a 2000 GB volume attached to the container. 11TB is the HDD on the node. The volume is writable, we can download files, no issues there ! See below,

:~# df -h
Filesystem      Size  Used Avail Use% Mounted on
overlay         448G   76M  448G   1% /
tmpfs            64M     0   64M   0% /dev
shm              64M     0   64M   0% /dev/shm
tmpfs           1.5G  971M  566M  64% /etc/resolv.conf
/dev/sdb         11T  1.7G     0 100% /dgb-data
tmpfs            63G     0   63G   0% /proc/acpi

tmpfs            63G     0   63G   0% /proc/scsi

Problem

The problem is that the client binary/software sees it as 100 % used and therefore aborts with the error that Disk space is low. Here is it,

~# ./digibyte/bin/digibyted --datadir=/dgb-data
2020-05-22T13:50:30Z Checking all blk files are present...
2020-05-22T13:50:30Z Initializing databases...
2020-05-22T13:50:30Z *** Disk space is low!
2020-05-22T13:50:30Z Error: Error: Disk space is low!
Error: Error: Disk space is low!
2020-05-22T13:50:30Z ERROR: out of disk space

We already know that btrfs subvolumes won't be able to show the correct used/free values inside the container, which is fine ! We need to understand why does it show 100 % and why not 0.1 % ?

/dev/sdb 11T 1.7G 0 100% /dgb-data
