Sometimes, during an IoT Server reboot, a disk will be flagged as corrupt. You must execute the FSCK function or restore a backup of the VM.
If you see this issue during a reboot of your IoT Server:
Reboot the virtual appliance, and immediately after the OS starts, press 'e' to open the GNU GRUB Edit Menu.
Locate the line that begins with the word 'linux'.
At the end of the line, add 'fsck.repair=yes', then reboot the appliance. This will force the default filesystem check to auto-resolve any issues, and does not require an emergency mode.
