This article will explain in detail how to check the file system type under Linux. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Linux supports a variety of file systems, including ext2, ext3, vfat, ntfs, iso9660, jffs, romfs and nfs. In order to manage all kinds of file systems uniformly, Linux introduces virtual file system VFS (Virtual File System) to provide a unified operation interface and application programming interface for all kinds of file systems.

1. Df-T command view

This is the simplest command, and the file system type is output in the Type column. You can only view mounted partitions and file system types. As follows:

[root@mylnx008 ~] # df-T / dev/sdbFilesystem Type 1K-blocks Used Available Use% Mounted on/dev/sdb xfs 315467264 4356404 311110860 / mysql [root@mylnx008 ~] # df-TFilesystem Type 1K-blocks Used Available Use% Mounted on/dev/sda2 xfs 30929148 22455300 847384873% / devtmpfs devtmpfs 1746644 0 17466444 0 / devtmpfs tmpfs 1757220 0 1757220 / dev/shmtmpfs tmpfs 1757220 24868 1732352 / runtmpfs tmpfs 1757220 01757220% / sys/fs/cgroup/dev/sda1 xfs 50858063024445556 13% / boot/dev/sdc1 ext4 1392030808699072 1234098407% / mnt/resourcetmpfs tmpfs 35144803514480% / run/user/1000/dev/ Sdb xfs 315467264 4356404 311110860 2% / mysql2 Parted-l command view

As shown below, the parted-l command outputs the file system type (File system), where the parameter l indicates that the partition information for all devices is listed.

[root@DB-Server ~] # parted-lModel: ATA ST500DM002-1BD14 (scsi) Disk / dev/sda: 500GBSector size (logical/physical): 512B/512BPartition Table: msdosNumber Start End Size Type File system Flags1 32.3kB 107MB 107MB primary ext3 boot2 107MB 500GB 500GB primary lvm3, blkid Command View

View the UUID and file system of the formatted partition. Use blkid to output the partition or the file system type of the partition and view the output of the TYPE field.

[root@DB-Server ~] # blkid/dev/mapper/VolGroup00-LogVol01: TYPE= "swap" / dev/mapper/VolGroup00-LogVol00: UUID= "1c0d5470-1503-4a18-b184-53483466d948" TYPE= "ext3" / dev/sda1: LABEL= "/ boot" UUID= "582b189c-396c-4da8-a7a3-1effaa3e4000" TYPE= "ext3" / dev/VolGroup00/LogVol00: UUID= "1c0d5470-1503-4a18-b184-53483466d948" TYPE= "ext3" / dev/VolGroup00/LogVol01: TYPE= "swap" / dev/mapper/VolGroup00-LogVol03: UUID= "f037ba1e -77a1-439a-8a10-b78c3cca68ec "SEC_TYPE=" ext2 "TYPE=" ext3 "[root@DB-Server] # blkid / dev/sda1/dev/sda1: LABEL=" / boot "UUID=" 582b189c-396c-4da8-a7a3-1effaa3e4000 "TYPE=" ext3 "4. Command lsblk-f to view

Some systems may not have this command and need to be installed. Note: lsblk-f can also view unmounted file system types

[root@mylnx008] # lsblk-fNAME FSTYPE LABEL UUID MOUNTPOINTfd0sda ├─ sda1 xfs b98659b2-5f8c-493e-9304-658905ef1391 / boot └─ sda2 xfs b7559ac5-b3a4-4b00-b98a-a2a2611806d0 / sdb xfs 6fcc5417-3c1b-4c71-aac7-344bac7654a4 / mysqlsdc └─ sdc1 ext4 1ad7da45-2366-4c4f-acd4-484600c4153a / mnt/resource
