Red LED. But SSH is on and I have access to my files. How to fix it?

My Cloud OS 3 Personal & Network Attached Storage My Cloud
12

I finally managed to fix the problem. I found the answer in this post. I just bound /DataVolume/cache at /CacheVolume with

mount --bind /DataVolume/cache /CacheVolume

and then started the update process and it worked! Now the storage is working again and I have full access to all my files.

Thank you rac8006 and cpt_paranoia for your time and help!
