Support Volume with ext4

[p-w-e]

I need a volume with the ext4 file system. Unfortunately, the software does not support btrfs with its DB.
Is it possible to create a volume with ext4?

No plans to make the default file system customizable, but you can create and mount a disk image:

truncate -s 64G ext4.img
mkfs.ext4 ext4.img
mkdir /mnt/data
mount ext4.img /mnt/data
