Recently this message popped up on the MOTD of the Ubuntu servers on EC2:
*** /dev/xvda1 will be checked for errors at next reboot ***
After proceeding to do a fsck and restarting, the message still kept appearing. After some debugging with wk, it apparently was due to a stale fsck-at-reboot file left around causing the message to keep popping up.
Here are the steps I used to make sure they stopped popping up again:
sudo touch /forcefsck
sudo shutdown -r now
sudo rm /var/lib/update-notifier/fsck-at-reboot
cd /usr/lib/update-notifier/
sudo ./update-motd-fsck-at-reboot
sudo rm /forcefsck
Thanks wk!
