Description
How to initiate a filesystem check at boot on the Raspberry Pi OS.
It’s not possible to run fsck (or e2fsck) on a mounted partiton. Therefore a filesystem check can be initiated at boot time.
Steps
Open cmdline.txt for editing
sudo edit /boot/cmdline.txt
Add fsck.mode=force to the existing line of text as shown below [1]
1 | console=serial0,115200 console=tty1 root=PARTUUID=6c586e13-02 rootfstype=ext4 elevator=deadline fsck.mode=force fsck.repair=yes rootwait |
Reboot the system
The filesystem check should be kicked-off as part of the boot process.
Depending on your custom user configuration, the system may require or prompt you to login to a root user session.
At this point you can review the log files.
Check log files
If you want to see the log entries generated, you can use the journalctl tool.
Example [1:1]
$ journalctl -u systemd-fsck*
This shows logs from the specified unit (-u), systemd-fsck*
$ journalctl -xb
This display items related to the current boot (-b) with message explainations where available (-x).
