     Formatting device already containing a known signature.
     Logical blocks defaulted to 18838215 blocks.
     The VDO volume can address 72 GB in 36 data slabs, each 2 GB.
     It can grow to address at most 16 TB of physical storage in 8192 slabs.
     If a larger maximum size might be needed, use bigger slabs.
