I run a home server with owncloud 10.0.3.3 installed over Ubuntu server 16.10.
Initially I had only 2 hard disks, a 500GB for the operating system and a 2TB for owncloud. Recently I have added a 3TB disk with the intention to increase the storage space for owncloud. I used mhddfs to merge the two partitions from the 2TB and 3TB disks into one single partition of 5TB. Then I changed the data directory in config.php to the new partition and everything was ok in the sense that owncloud is running fine.
However, if I go in my owncloud admin interface and give a user 3TB of storage this is not correctly shown in the user interface. When the user opens its own interface, a different number, way smaller (for example 1.6 TB only) is shown.
I paste below the outputs from fdisk, lsblk and df.
Thank you in advance for your help.
