How to force fsck at every boot in Linux
- In
/etc/init.d/checkfs.shis the lineif [ -f /forcefsck ] || grep -s -w -i "forcefsck" /proc/cmdline, so providingforcefsckon the kernel command line or generating a/forcefsckfile on shutdown should cause an fsck on the next reboot.To prevent manual fsck runs, ask
fsckto try to automatically fix errors with the-yoption by uncommenting and changing no toyesin the following /etc/default/rcS entry, after the edit it should look like:

# automatically repair filesystems with inconsistencies during boot FSCKFIX=yes</code><code> |
- One option (forcefsck or FSCKFIX) does not imply the other.
- according to manpages -c argument for tune2fs counts number of instances of mounts for a partition. Hence, 1 forces to check the fs after every mounting instance. (http://man7.org/linux/man-pages/man8/tune2fs.8.html)
