[Bug 1797282] Re: fsck not running at all on reboot

[Phil Pemberton]

I'm seeing this on an Ubuntu 16.04.5 LTS system running on top of LVM.
In my case, I get:


*** /dev/mapper/wolf-root will be checked for errors at next reboot ***


Having to dig out a 16.04 LTS Server USB stick every time I need to run FSCK is extremely inconvenient. It turns an unattended maintenance job into one that requires a lot of hand-holding.

Please let me know if there's any information I can provide to get this
fixed.

Title:
  fsck not running at all on reboot

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  After upgrading some servers from 16.04 to 18.04 I'm met with a MOTD
  that says:

  *** /dev/xvda1 should be checked for errors ***

  I added "fsck.mode=force" to GRUB_CMDLINE_LINUX_DEFAULT in
  /etc/default/grub before running 'sudo update-grub'. I also verified
  that fsck was present in /boot/grub/grub.cfg afterwards, before
  rebooting the server.

  Surprisingly I was met with the same error message in MOTD when
  logging in. I then ran tune2fs to see when the last check was
  performed and this is the output:

  $ sudo tune2fs -l /dev/xvda1  | grep checked
  Last checked:             Wed Sep 12 16:17:00 2018

  I then tried to change mount count to 1 with tune2fs -c 1 /dev/xvda1,
  but after another reboot I was still met with the same error message
  and the timestamp for last checked was unchanged.

  I have the same problem on all the servers that was upgraded from
  16.04 to 18.04, but also on a new server installed directly with
  18.04.

  In should be mentioned that the servers are AWS EC2 instances, so I
  have no way of trying to run fsck from a liveusb.

  Another user has reported the same issue here:
  https://ubuntuforums.org/showthread.php?t=2403368

  I'm not quite sure what information is needed, but attached are some
  basic information about the system.

  Please let me know if you need any any other outputs or logs.

  Edit1: I tested fsck.mode=force on my laptop running Ubuntu 18.04.1
  LTS (Xubuntu) and it works fine. Seems to be related to the server
  edition.
