How To Easily Fix Linux Filesystem Type Checking
August 26, 2021
Recommended: Fortect
If you see the checkbox “Check Linux file system type”, the following tutorial will help you.
- Using the df command df command term …
- Using the fsck fsck command also …
- Using the lsblk lsblk d … command
- Using the support mount c command …
- Using the blkid blkid c … command
- Use the command image com file …
- Use the fstab file
If the filesystem is not mounted (but if everything is fine):
blkid as -o value -adverts TYPE / dev / block / device -Ls / dev / block / device file Usually you need read access to a locked phone. However, if it cannot read the device in blkid , it tries to retrieve this assembly information stored in /run/blkid/blkid.tab or perhaps /etc/blkid.tab .
lsblk -no FSTYPE / dev / block / device will also allow you to get information this time, as well as query the udev data (something like / run / udev / data / b $ major: $ minor ) ...

Linux systems may differ slightly. They support several different file sizes and mechanisms such as journaling, etc. In addition, different types due to the supported file systems are supported by prominent Linux kernel systems. So, for devices availableas disk space on Linux system, we can definitely identify their file by type using the following commands.
Use Lsblk
All connected devices are shown here, indicating their types and sections.
$ lsblk -f

Use File
file $ sudo -sL / dev / sda1[sudo] code for Ubuntu:

Use Fsck
Although fsck is primarily used for file system maintenance, it also checks file types. Fsck
$ -N / dev / sda1
fsck between util-linux 2.27.1[/sbin/fsck.ext4 (1) - /] fsck.ext4 / dev / sda1
Show In / Etc / Fstab
This is your own file containing information about points, file system types, etc. We only need the hamster command to get its contents.
cat / etc / fstab
# / etc / fstab: static filesystem information.## Use 'blkid' to output the universally uniqueidentifier a# for the device; this will probably be used with UUID = as a newer, more reliable way to enumerate devices# also works when adding and removing hard drives.

Use Df
The df command with the off - th option provides a very detailed view of all file type information, as well as sufficient reasons for percentage usage and details about mount location.
$ df -Th

In computing, any file system is a layout or format created for storage Storage device in files. The file system is used to support the logical separation of the storage in the cable box, so that the various files in the storage are well organized so that they can be easily viewed, viewed, edited, deleted, etc. from behind the storage device.
There are many file systems available today. Various file systems have unusual structure, logic, functions, flexibility, security. Some of the most popular file systems are: Ext4, Btrfs, XFS, ZFS, NTFS, FAT32, etc.
Sometimes a key Linux system administrator needs to determine the type of filesystem just to mount the filesystem or assess problems with the filesystem. Different filesystems have different tools for diagnosing, debugging, fixing people, etc. Therefore, you need to know which filesystem the storage device is currently using in order to determine which software tools to use.
In this article, I have the opportunity to show you various ways to finally determine the type of fileth Linux system. So let's get started.
Method 1: Using The Df Command Line Tool
df command line support is preinstalled on almost all Linux distributions you can find. You can use the df command line approach to find the filesystem type, mostly attached storage devices, as well as partitions.
To determine the file system type of all connected storage devices and the partitioning of your computer, run the df command as follows:
The df command will probably show you the following information:
File System: The name of the attached storage device or partition.
Mounted in: the directory where the storage device / partition (file system) is mounted.
In Use: A blank disk used by the installed storage device / partition.

The
in df get will show you a lot of looping technologies, as you can see in our screenshot below.
The following can be used to hide these loopback devices with the -x clause of the df command:
You can also hide tmpfs files on devices that generate df command output.
To hide tmpfs devices that were also obtained from df get output, run the df command with the -x parameter in the following role:
You look much cleaner now. You can remove any udev device from the df command output if you like.
