After a fresh Install of omv I have a error message "export PATH=/bin:/sbin:/usr" while mounting one of my hard drives

Hello,

after a fresh Install of the latest omv version I wanted to mount my 4 hard drives but one of them gets a error message.

..."Executing background process failed: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin;"

Can someone help me to what I have to do, or is my hard drive broken?

I'm overwhelmed and can't get my head around it. Unfortunately, my English isn't the best either, so I don't understand some of the linked posts. How can I check the hard disk if it is not mounted? Or should I take this to mean that it is the system hard disk that is full, whereby I then ask myself why I was able to mount all the other hard disks and all my folders are also present. I am trying to understand this. When I give the command, I get the following result:

In this case the full disk would be /dev/sdc1 which is not a system disk but only for data. The /dev/sda1 is only 5% full so I don't know if it can really solve my problem. The disk was still running this morning before I removed all disks except the system disk to do a fresh installation.
