I use to order fsck by doing:

# touch /forcefsck

On Ubuntu Linux v14 I have found this method to check if, after rebooting, it was performed:

luis@Terminus:~$ sudo dumpe2fs /dev/sda7 | grep "mount" -i
dumpe2fs 1.42.9 (4-Feb-2014)
Last mounted on:          /
Default mount options:    user_xattr acl
Last mount time:          Sun Feb 28 23:24:18 2016
Mount count:              1
Maximum mount count:      -1

The trick is in the Mount count data: it is supposed to tell the number of times the partition has been mounted after the last check. So a number of 1 after rebooting means it was just checked right now.

But on Kali Linux v2.0 it seems not to be working all right. This is the result after the same touch /forcefsck command:

luis@Midnighter:~$ sudo dumpe2fs /dev/sdb8 | grep "mount" -i
dumpe2fs 1.42.12 (29-Aug-2014)
Last mounted on:          /
Default mount options:    user_xattr acl
Last mount time:          Sun Feb 28 21:22:49 2016
Mount count:              82
Maximum mount count:      -1

How could I confirm fsck was performed?

There's a direct way of telling when fsck was last run on the filesystem:

tune2fs -l /dev/sdb8 | grep '^Last checked:'

(or dumpe2fs instead of tune2fs -l.)

On Debian, the presence of /forcefsck causes the boot scripts to run fsck -f instead of fsck, which forces a filesystem check (normally fsck just says that the filesystem is clean and exits immediately). I don't know if Kali Linux has changed the relevant script (/etc/init.d/checkroot.sh on a SysVinit system).

  • Indeed, at Kali the forcefsck trick does not work. I have finally succeded with this method based on mounting the root partition as read-only, reboot, fsck, reboot and remount as read-write again: bitsofmymind.com/2014/03/14/… . Tested working via SSH. Feb 29, 2016 at 1:40
  • It is hard to believe that there is no easy/quick way to check your root file system on Linux. Even Windows can do it via chkdsk /f. Feb 29, 2016 at 1:43
  • @SopalajodeArrierez why do you think you should want to check the root file system?
