This morning I was unable to connect to my machine via the web panel so I tried to reboot the system manually by pressing the power button but around 2 hours later it hadn't turned off so I held the button for a few seconds, then a few seconds after letting go it turned off. When the system was back online one of my disks was showing "Unmountable: No file system". Since seeing this all I have done is let the parity check finish, download the diagnostics, reboot the system, then turn the array off.
How can I fix this?
