最近在看lvm分区，基础没打好，累啊。遇到了很多问题。查看分区的文件系统格式有几个命令。分别列出来,我想说的是centos7 默认是xfs格式。
先说最简单的，下边的有需要了你看。
centos7的
[root@localhost ~]# df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/mapper/centos-root xfs 18860032 1375224 17484808 8% / devtmpfs devtmpfs 886508 0 886508 0% /dev tmpfs tmpfs 898636 0 898636 0% /dev/shm tmpfs tmpfs 898636 9864 888772 2% /run tmpfs tmpfs 898636 0 898636 0% /sys/fs/cgroup /dev/sda1 xfs 1038336 151272 887064 15% /boot tmpfs tmpfs 179728 0 179728 0% /run/user/0
这个是centos6
