linux下查看文件系统类型

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  4.5G   13G  26% /
devtmpfs              devtmpfs  911M     0  911M   0% /dev
tmpfs                 tmpfs     921M     0  921M   0% /dev/shm
tmpfs                 tmpfs     921M  8.4M  912M   1% /run
tmpfs                 tmpfs     921M     0  921M   0% /sys/fs/cgroup
/dev/sdb1             ext4      4.8G   20M  4.6G   1% /testdisk
/dev/sda1             xfs       497M  124M  374M  25% /boot
tmpfs                 tmpfs     185M     0  185M   0% /run/user/0

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
