View Full Version : [SOLVED] problem running fsck

sudo fsck
/dev/sdal is mounted
Running e2fsck on a mounted filesystem may cause severe filesystem damage
I have no idea how to fix this problem.Thanks

You can also do this:

sudo touch /forcefsck

That will force a fsck on your root directory after you reboot. If you have multiple partitions (such as a seperate partition for your home directory) you'll want to do that same command for it with the respective path modified. If you don't know what that means, then the above command should be all you need to do.

how do you umount /dev/sdaI while booting livecd being new to UBUNTU?

It is my understanding that if you boot from the cd the hard drive is not mounted. And in turn you can run your fsck without fear because the disk is not mounted.

So simply insert the livecd, and then run the fsck from you terminal once the livecd has loaded.
