Great work with all the benchmarks! I greatly appreciate your job.
I don't know if I'm doing it wrong but instead of building the OMV image for my board (Orange pi One) I downloaded the pre-built jessie image from armbian website and run the customize-image.sh.template:
mv customize-image.sh.template omv.sh
nano omv.sh # uncomment InstallOpenMediaVault
chmod 700 omv.sh
./omv.sh jessie sun8i orangepione no
Is it equivalent to building the whole image from ground up?
By the way, the above process fails because the space in the sd card becomes full.
