If you want to manually run filesystem check after server reboot then please follow the below commands.
Create forcefsck file:
The file /etc/rc.sysinit is used to run fsck command.
[root@server ~]# touch /forcefsck
Now reboot the system:
[root@server ~]# shutdown -r now
Some of modern distribution linux does not support above command. For that, use -F options,
[root@server ~]# shutdown -rF now
