My data device and metadata device are both 4G.
The recommend dedup ratio is 1.5, when i make a ext4 filesystem on the "mydedup", then "mount" will failure with "read superblock error". I try to change the dedup ratio to 1.4, 1.3, 1.2, 1.1, the "mount" will success on all of them.
But i don't know why.
