I have been stuck, uninstalling and reinstalling OMV on my new pi 4 multiple time in the past couple of days, and narrow the problem down to unionfs plugin. Once I installed and pool my 3 drives together, next reboot will stuck at the "root account is locked". The server only become bootable again, once I edit in the cmdline.txt in the sd card, edited the fstab to remove the line added by the unionfs plugin.
Below is the error message from the boot screen:
This is the line I need to remove from my fstab in order to get it bootable again.

I am novice in linux, so any help to assist me me running unionFS in my OMV is greatly appreciated.
