1. df -hT命令
-h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)
-T, --print-type print file system type
[root@rhel7 ~]# df -hT
Filesystem Type Size Used Avail Use% Mounted on
/dev/mapper/rhel-root xfs 18G .5G 13G % /

/dev/sda1 xfs 497M 124M 374M % /boot
tmpfs tmpfs 185M 185M % /run/user/
xfs是RHEL7版本默认的文件系统类型。
2. 使用parted磁盘管理工具查看
[root@rhel7 ~]# parted
