My motd persistently has:

*** /dev/sdb1 will be checked for errors at next reboot ***

The problem is that I don't have /dev/sdb1 on my system.

I only have /dev/sdb2 (mouted as /) and /dev/sda1 which mounts to /media/backup. I delete that line from /etc/motd, but it reappears after reboot. Here's my df output:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb2        73G  3.7G   66G   6% /
udev            490M  4.0K  490M   1% /dev
tmpfs           200M  760K  199M   1% /run
none            5.0M     0  5.0M   0% /run/lock
none            498M     0  498M   0% /run/shm
/dev/sda1       1.9T  429G  1.4T  25% /media/backup

Update

Here is the output of sudo fdisk -l

Partition table entries are not in disk order

I guess /dev/sdb1 is my swap space.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
Please add the output of sudo fdisk -l to your question. –  Takkat May 24 '12 at 6:48

From: Persistent "disk will be checked..." in the message of the day (motd) even after reboot

This is caused by a stuck file. The timestamp on /var/lib/update-notifier/fsck-at-reboot is in the future, causing it never to be regenerated.

To fix the problem, remove that file and then reboot.

You can fix it without rebooting by forcing the motd file to be regenerated after removing the stuck file.

Here is the command to remove the stuck file and regenerate it through the update-motd system:

sudo bash -c 'rm /var/lib/update-notifier/fsck-at-reboot && for file in /etc/update-motd.d/*; do $file; done > /var/run/motd' && cat /etc/motd

Or alternately, with run-parts instead of the for loop:

sudo bash -c 'rm /var/lib/update-notifier/fsck-at-reboot && run-parts /etc/update-motd.d | tee /var/run/motd'

Looking for help on the same issue, and the search that brought me here.

I came across this forum discussion Ubuntu Forums which posed the following command as solution:

sudo touch /forcefsck

I tried it and the message was cleared on next reboot. Some have commented that this does not always work, but I hope it helps you too.

It does look like it might be a swap problem. Can you manually fsck the drives from single-user mode (e.g., by booting into recovery mode)?

You can do a sudo mv /var/run/motd /var/run/motd.old to force a clear of the current /etc/motd file.

Also, can you add output of your from cat /etc/fstab ?


For swap operations, see these answers:

delete old swap partition

How to delete a second swap partition safely?

A nice graphical swap repair guide using gparted is here.

The message comes back when I login again. –  kmm May 24 '12 at 14:50
    
Now the message has changed to /dev/sda1. I rebooted, but that disk was not checked. I ran the command above again, but the message returns. –  kmm May 24 '12 at 14:57
    
The message that returns is about sda1 or sdb1 this time? –  belacqua May 24 '12 at 15:00
    
Correct -- sda1 now. –  kmm May 24 '12 at 15:22
