centos 查看磁盘分区的文件系统类型
sdb 这块磁盘是parted分的 gpt分区 1.lsblk -f这个命令是查看系统可以识别出的所有分区的文件系统类型
[root@centos7~]#df-h###可以看到sdb1分区现在没有挂载文件系统容量已用可用已用%挂载点/dev/sda31.1T1.1T61G95%/devtmpfs5.8G05.8G0%/devtmpfs5.8G4.0K5.8G1%/dev/shmtmpfs5.8G8.6M5.8G1%/runtmpfs5.8G05.8G0%/sys/fs/cgroup/dev/sda1473M169M305M36%/boottmpfs1.2G01.2G0%/run/user/0tmpfs1.2G01.2G0%/run/user/1006[root@centos7~]#lsblk-fNAMEFSTYPELABELUUIDMOUNTPOINTsda├─sda1xfsd964d76c-14ce-4eeb-a158-0953269cdb27/boot├─sda2swap3056f427-b0a4-45f3-8d14-8961b21a4ca3[SWAP]└─sda3xfs429d95a7-378c-4b38-a418-3dbb4dde9407/sdb└─sdb1xfs7bf40c0e-b383-4bc1-a443-32493c6637e1sr0 2.blkid查看已格式化分区的UUID和文件系统。使用blkid可以输出分区或分区的文件系统类型，查看TYPE字段输出。

parted-l命令会输出分区类型( msdosgpt)参数l(list)表示列出所有设备的分区信息。
