Hey there.
I use OMV for many years now and never had any problems. For me, Linux is a closed book. So I need some help.
My OMV contains three software raids: md0, md1, md2. Some days before I deleted md0 and created a new raid which gets the md0 again. After the raid was created succesfully I wanted to mount the file system (ext4), but I always get a failure 500 - Internal Server Error (see below). Can somebody help please?! 
Code
