ks in a snapshot, cache pool or thin pool.
For snapshots, the value must be a power of 2 between 4 KiB and 512 KiB
and the default value is 4.
For a cache pool the value must be between 32 KiB and 1 GiB
and the default value is 64.
For a thin pool the value must be between 64 KiB and 1 GiB
and the default value starts with 64 and scales up to fit the
pool metadata size within 128 MiB, if the pool metadata size is not specified.
The value must be a multiple of 64 KiB.
