Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Run a file system check on your next boot.

The empty file /forcefsck causes the file system check fsck to be run next time you boot up, after which it will be removed.

This works too:

sudo >/forcefsck

What others think

Which distro are you on ?

It works on redhat Fedora and RHEL, but I'm not sur for the others.

Works for Debian and Ubuntu, too.

Comment by funollet 370 weeks and 3 days ago

Great command! It's a kernel functionality or just some distro specific?

Comment by funyotros 370 weeks and 2 days ago

Seems to be a general Linux facility.

Comment by johnraff 369 weeks and 6 days ago

No, it's not in the Linux kernel. In Debian, it's implemented in /etc/init.d/checkfs.sh and checkroot.sh with a line that looks like this

if [ -f /forcefsck ] || grep -s -w -i "forcefsck" /proc/cmdline

Skimming through those files, I notice that you can do the opposite (force skipping fsck) by creating the file "/fastboot"

sudo touch /fastboot
