Ubuntu – Ubuntu 18.04 fsckd is not completing the filesystem check process and also not able to cancel the process by pressing Ctrl+C

18.04filesystem

My system is running on Ubuntu 18.04 is stuck on fsckd check, I am not able to cancel this check and also not able to see any progress of the check after the prompt bellow.

fsckd-cancel-msg:Press Ctrl+C to cancel all filesystem checks in progress

Screenshot of the check

I have tried skipping the check, but no luck.

I want to find out what's the actual problem here as it's taking long time for the filesystem check and the reason for starting this filesystem check process at the first place.

Is skipping this check is a good option here? if so, can you guide me through what needs to be done exactly. If skipping the check is not a good option then what needs to be done.

Any help will be much appreciated.

  • Let's check the basics first, by performing a manual fsck...

    • boot to a Ubuntu Live DVD/USB
    • open a terminal window
    • type sudo fdisk -l
    • identify the /dev/XXXX device name for your "Linux Filesystem"
    • type sudo fsck -f /dev/XXXX # replacing XXXX with the number you found earlier
    • repeat the fsck command if there were errors
    • type reboot

    Update #1:

    Ah, you've partitioned your disks slightly out of the ordinary, so we'll have to fsck the other partitions also.

    • boot to a Ubuntu Live DVD/USB
    • open a terminal window
    • type the following commands...
      • sudo fsck -f /dev/sda4
      • sudo fsck -f /dev/sda1
      • sudo fsck -f /dev/sdb1
      • sudo fsck -f /dev/sda5

    Update #2:

    We're investigating high read/seek/ECC error rates on sdb (HDD).

    There may also be a Ubuntu software issue, or sda (SSD) firmware issue.

    Update #3:

    In looking at gparted for sda (SSD) I see /var is full.

    I'd recommend:

    • full backup of important files from /home/username from sdb (HDD)
    • perform firmware update on sda (SSD) if required
    • wipe sda (SSD) and install fresh Ubuntu WITHOUT separate /var or /home
    • do not install anything on sdb and we'll do a bad block scan, and see if fsckd problem is gone

    Update #4:

    Bad block scan on sdb...

    If sdb is not empty, use the appropriate partition number (probably sdb1 in your case) for the sdXX parameter below. If sdb is empty, assure that there's at least one large ext4 partition, which will probably be sdb1, and then use that for sdXX.

    Note: do NOT abort a bad block scan!

    sudo e2fsck -fcky /dev/sdXX # read-only test

    or

    sudo e2fsck -fccky /dev/sdXX # non-destructive read/write test (recommended)

    The -k is important, because it saves the previous bad block table, and adds any new bad blocks to that table. Without -k, you loose all of the prior bad block information.

    The -fccky parameter...

       -f     Force checking even if the file system seems clean.
    
       -c     This option causes e2fsck to use badblocks(8) program  to  do  a
              read-only  scan  of  the device in order to find any bad blocks.
              If any bad blocks are found, they are added  to  the  bad  block
              inode  to  prevent them from being allocated to a file or direcā€
              tory.  If this option is specified twice,  then  the  bad  block
              scan will be done using a non-destructive read-write test.
    
       -k     When combined with the -c option, any existing bad blocks in the
              bad blocks list are preserved, and any new bad blocks  found  by
              running  badblocks(8)  will  be added to the existing bad blocks
              list.
    
       -y     Assume  an answer of `yes' to all questions; allows e2fsck to be
              used non-interactively.  This option may not be specified at the
              same time as the -n or -p options.
    

    Update #5:

    Bad blocking completed. SMART Data indicates that read/ECC errors are now zero! If read/seek/ECC errors return, suspect a bad SATA cable or SATA port. Monitor SMART Data for sdb.

    Reinstall Ubuntu with no special partitioning, except for /home on ext4 sdb1, and possibly a sdb2 NTFS partition if you share files with Windows.
