获得Linux文件系统的block size
参考文章:What is the Block Size Limit in XFS Filesystem on Oracle Linux 7 (Doc ID 2101949.1)

[root@localhost ~]# df -ThFilesystem     Type   Size  Used Avail Use% Mounted on/dev/sda3      ext4    16G   15G  607M  96% /tmpfs          tmpfs  935M     0  935M   0% /dev/shm/dev/sda1      ext4   190M   40M  141M  23% /boot[root@localhost ~]#  blockdev --getbsz /dev/sda34096[root@localhost ~]#

注意,本文所说的block siz是文件系统的block size,不是sda的block size.
