mkfsxfs -K解释

mkfs.xfs -K is a command used to create an XFS file system with a specific block size.

The -K option specifies that the file system should be created with a specific block size instead of using the default block size. The block size determines the smallest unit of data that can be read from or written to the file system.

By using -K option, you can specify the block size in bytes, such as 4096 (4KB), 8192 (8KB), 16384 (16KB), or 32768 (32KB), depending on your requirements and the capabilities of your storage device.

Note that changing the block size may have an impact on the performance and efficiency of the file system, so it is important to consider the trade-offs before choosing a specific block size.
