Hello,
i just installed OMV the first time on a Odroid HC1.
It is up and running.
Now I'd like to set up a full disc encryption for the SDCard (exclusiv /boot) [and later the HDD] following this HOWTO:
[HowTo] OMV 4.x LUKS Full Disk Encryption, unlock via SSH
The HOWTO suggests to boot a live Image from USB, but the Odroid HC1 isn't able to do so.
So i figured to use another SDCARD, put a fresh OMV Installation onto ist and use this one as "Live system".
But when i insert the "to be encrypted SDCard" (within an USB-SDCard reader) into the USB Port, a couple of
(auto-)mounts show up: (with sdb beeing the "to be encrypted SDCard" )
>root@odroid:~# mount | grep sdb

>/dev/sdb2 on /var/folder2ram/var/cache/samba type btrfs (rw,noatime,nodiratime,compress=lzo,ssd,space_cache,commit=600,subvolid=5,subvol=/var/cache/samba)
Especially the: /dev/sdb2 on / makes me think that some systemrelevant changes happend auomagically.
The USB-SDCard became the root-filesystem Seems to be some some Feature that i just don't need.
Can somebody please tell me how to turn this automount (of the USB device as / and all the others) off!
