系统打印信息
[root@stor37 home]# mkfs.xfs /dev/sdb
-bash: mkfs.xfs: command not found
-
解决方案：
运行which mkfs查看mkfs的命令目录
[root@stor37 home]# which mkfs
/sbin/mkfs
[root@stor37 home]# ls -la /sbin/mkfs*
-rwxr-xr-x. 1 root root 10336 Mar 15 2016 /sbin/mkfs
-rwxr-xr-x. 1 root root 26208 Mar 15 2016 /sbin/mkfs.cramfs
-rwxr-xr-x. 5 root root 68960 Jun 5 2015 /sbin/mkfs.ext2

-rwxr-xr-x. 5 root root 68960 Jun 5 2015 /sbin/mkfs.ext4
-rwxr-xr-x. 5 root root 68960 Jun 5 2015 /sbin/mkfs.ext4dev
lrwxrwxrwx. 1 root root 7 Feb 25 00:37 /sbin/mkfs.msdos -> mkdosfs
lrwxrwxrwx. 1 root root 7 Feb 25 00:37 /sbin/mkfs.vfat -> mkdosfs
发现缺失相应xfs包，需要安装xfsprogs的rpm包
