If you have different filesystems on your drive and want to check a specific type of filesystem then you can use –t flag. You may want to read: How to become root user in Ubuntu Running fsck for a specific filesystem To prevent fsck to run at every startup, you simply need to delete the ‘forcefsck’ file in the root directory. You can overcome this problem by simply adding an empty file named “forcefsck” in the root directory. If you check root partition with fsck while it is mounted then you might damage it and you won’t be able to boot anymore. Check root partition for errors with fsck Here, ‘x’ is drive number and ‘y’ is partition number. Then, via the command below, you can then check the desired filesystem : First, you will need to check the file system of a partition using the following command: You can check a particular file system with fsck. You may want to read: How to find the largest files on Linux Check a particular filesystem Keep in mind to replace x with the drive number and y with the partition number. This will only work with the flag –A.įTo perform an automatic repair after fsck errors check, use the following command: To prevent fsck from checking root, use –R flag. This will prevent checking mounted filesystem. To overcome this problem, you should use this command with –M flag. As I said earlier, there is a higher chance you might damage the it. Keep in mind though that this command will also check errors for the mounted filesystem. This command will grab all the partitions and filesystem information from /etc/fstab file and scan them for errors.

Keep in mind that you should never check a mounted filesystem with this command since this might damage those filesystems. First, we will learn how to use fsck in the command line. If you ever run into a filesystem error and want it solved then you are at the right place. fsck is the short form for ‘file system consistency check’. These filesystems can become corrupt over time and will therefore result in random system crashes, apps malfunctioning and frequent reboots.įsck comes to the rescue here. To each filesystem is assigned a set of rules which control the allocation of space (on the disk) to files and the way data about each file is associated (known as meta data) with that file (like filename, file directory its permissions and its date of creation ). Filesystems can be identified as a hierarchy of directories (or a directory tree) which determines the way files are stored and organized on a computer system.For example, a given Linux installation can be installed using only the ext1 filesystem instead of using both ext2 and ext3 filesystem types. An example of that would be my own disk usage indicator.Īnother way is via udevadm management utility for udev subsystem.If you have been using a Linux distribution, you might have encountered filesystems errors somehow. Udisk2 provides D-Bus interface, so if you ever want to use that in your own scripts or applications - it's possible. In particular, udisksctl status command is useful if you want to find out the information without root privileges locally. Ubuntu comes with UDisks2 library, which provides udisks daemon and couple command-line tools to query disk information and otherwise manipulate the drives.
