Subject: Re: [PATCH v3 2/2] md: allow configuring logical_block_size


> Previously, raid array used the maximum logical_block_size (LBS) of
> all member disks. Adding a larger LBS during disk at runtime could
> unexpectedly increase RAID's LBS, risking corruption of existing
> partitions. Simply restricting larger-LBS disks is inflexible. In some
> scenarios, only disks with 512 LBS are available currently, but later,
> disks with 4k LBS may be added to the array.
