Hello everybody!
I'm in big trouble and fear of losing everything^^:
My logical RAID 5 is not detected anymore in OMV:
I can only see separate disks under "disks":
My disks are /dev/sdc/dev/sdd /dev/sde /dev/sdf
Anything i can do to recover my RAID and datas? 
Thnks for this: missed it: all my apologies:
