|If you want to force fsck on the next reboot? How do I force fsck on a Linux based server or laptop? Is there any configuration file that I need to alter for this purpose on a Linux?|
fsck command is used to check and optionally repair one or more Linux file systems. You don’t have to create or alter/modify any file. All you need to do is just create empty file called /forcefsck.
How does fsck force work at every boot on a Linux?
On a RHEL/CentOS 6.x /etc/rc.sysinit file is used to run fsck command. If there is a /fsckoptions file, the options are loaded from the /fsckoptions file. If there is a /forcefsck file, -f is added.
Force fsck on boot using /forcefsck
By creating /forcefsck file you will force the Linux system (or rc scripts) to perform a full file system check. First, login as the root user:
$ su -
$ sudo -s
Change directory to root (/) directory [optional]:
# cd /
Create a file called forcefsck:
# touch /forcefsck
Now, reboot the system:
Force fsck on next boot using shutdown command (may not work on many modern distros)
The -F option force fsck on reboot, login as root and type the following command to reboot and run fsck:
# shutdown -rF now
The above will check all the relevant partitions immediately.
