fsck e2fsck: Cannot continue, aborting [duplicate]

  • 772

When I tried to run fsck on Ubuntu 18.04 recovery-mode I got the following message. Can anyone tell me why?

/lib/recocery-mode/recovery-menu: line 80: /etc/default/rcS: No such file or directory
fsck from util-linux 2.31.1
/dev/sda4 is mounted
e2fsck: Cannot continue, aborting.
mount fsck recovery-mode

  1. You don't say what command you're using, so do it this way...

    To check the file system on your Ubuntu partition...

    • boot to the GRUB menu
    • choose Advanced Options
    • choose Recovery mode
    • choose Root access
    • at the # prompt, type sudo fsck -f /
    • repeat the fsck command if there were errors
    • type reboot

    If for some reason you can't do the above...

    • boot to a Ubuntu Live DVD/USB
    • start gparted and determine which /dev/sdaX is your Ubuntu EXT4 partition
    • quit gparted
    • open a terminal window
    • type sudo fsck -f /dev/sda4 # replacing 4 with the number you found earlier
    • repeat the fsck command if there were errors
    • type reboot
    • 4

  2. The error is telling you that you cannot use e2fsck while the target file system is mounted. You must unmount the file system first using umount /dev/sda4. If you're currently booted into a system that has that volume mounted it's likely that you cannot unmount it. You should probably use a USB stick and run e2fsck from that.
