Hi, I just installed NC on my QNAP as a Virtualization Station VM, all worked like a charm. When setting up the VM, I created a Virtual Disk of 4TB and during the UBUNTU 20.04 Server install, I selected LUKS encryption, as I want the data on the disk to be encrypted when at rest (I have had bad experience with the integrated end-to-end encryption in the past and on mobile devices…)
All worked just fine but I shortly after realized the partition was only 200GB in size strangely enough, this is my FDISK output:
Disk /dev/loop0: 29.9 MiB, 31334400 bytes, 61200 sectors

This is the drive that is only 200GB:

So my question is, does anybody have a step by step instruction how to resize and encrypted LUKS partition with Nextcloud on it? Noteworthy I am still at early stages of the process, and if easier, I could re-install Ubuntu Server with NextCloud…
Worth pointing out:
- I have physical access to the QNAP that hosting the VM
- SSH is obviously working
- if you all tell me it’s a stupid idea to use LUKS encryption on a NC instance, I’d reconsider an unencrypted volume which I can managed in an easier way in terms of GPARTED and FDISK…
Thanks!!
