XFS is a high-performance 64-bit journaling file system created by Silicon Graphics, Inc (SGI) in 1993.
Set back the Mount Count parameter, or it will keep performing disk scans on each Linux boot. Linux command fsck is now check your Ext4 disk partition on startup.Īfter reboot, get the Last Checked value for your disk partition, now it will show you the time of last Linux startup. You have to modify the Mount Count parameter for that disk partition. To enable disk checking at the time of Linux startup. # mount -aĮnable Scanning of Ext4 Disk Partitions at Linux Startup: dev/sda1: clean, 320/65536 files, 61787/262144 blocksĪfter checking and repairing your Linux disk, mount the partition again at its respective mountpoint.įor this purpose, execute following Linux command to mount all the disk partitions listed in / etc/fstab file. # umount /dev/sda1Īfter successful unmount, execute fsck command at Linux bash prompt. But you are required to unmount that partition before checking and repairing it. To scan a Linux disk partition, you can use fsck (File System Consistency Check) command. Scan & Repair a Ext4 Type Disk Partition: You can find the last scan time for Linux Ext4 type partitions with the help of following command. You can execute the lsblk command with following switches at the Linux bash prompt to list the required information. If you are not used to Linux commandline then we recommend that you should attend online training Linux Command Line: From novice to wizardīy using a console or a ssh client, connect with your Linux server as root user. (Source: Wikipedia)įirst of all you need to identify the disk partitions in your Linux server, their respective file systems and the path where they are being mounted. The exact behaviors of various fsck implementations vary, but they typically follow a common order of internal operations and provide a common command-line interface to the user. The command works directly on data structures stored on disk, which are internal and specific to the particular file system in use - so an fsck command tailored to the file system is generally required. Generally, fsck is run either automatically at boot time, or manually by the system administrator. The system utility fsck (file system consistency check) is a tool for checking the consistency of a file system in Unix and Unix-like operating systems, such as Linux, macOS, and FreeBSD.
