I've just installed the last OMV for the Raspberry Pi 3 into a 32GB sd card. I can see two partitions in File Systems: one vfat (62 MiB) and one ext4 (3.52 GB). I thought OMV automatically created a third partition with the remaining free space.
In any case, if I try to create it myself, no devices are listed while doing so. Any clues on how to solve this, or if I can at least expand the ext4 system to save my data there?
