Hello,
I try to install OMV in raspberry pi 2 in sd card 16Go and RAID (3 usb key of 128Go) and image omv 2.2.1_rpi2.
I am a new user OMV and I did some trial and error but I wanted to remake a clean intallation and I have this error message and I know how to remove it .
I'm a beginner in linux .
best regards,
Wyrus
