Hello!
I'm trying now for some days to get an OMV installation run, but when i reboot the NAS the system hangs at once and evey time. I have tried it a dozen times every time the same problem.
Hardware is TerraMaster F2-220, Bootdevice is a 64GB Micron SSD with an USB-to-SATA adapter.
I have installed OMV using Virtualbox (boot from openmediavault_3.0.94-amd64.iso and installed it on the SSD as descipted in an article of ct magazine)
The NAS boots fine the first time, I can access the web interface, everthing seems to work. But when i make some config changes (i.e. add a user, set up email notification, and the ntp server) and reboot afterwards the system hangs.
I have mounted the SSD to another Debian system and have a look at the kern.log. The last line is "kernel: [ 6.910268] random: crng init done".
As there is no display on the F2-220 I have connected the SDD to an Intel Atom System and tried to boot.
The Grub menu appears, then an message about initialising ramdisk ? and then the screen resolution changes and a blinking cursor appears (forever).
The only soulution I found up to now was to start the whole installation again, but now after a dozen installations all with the same result I'm very frustrated.
When I don't use the Web interface for configuration, but open a shell via putty, then I can install additional packages (i.e. editior joe) and reboot the system by "shutdown -r now" as often as I want, no problem, but doing a litte config change via Web interface and the installation is for the trash. 
Can anyone help?
Best regards
Erich
