How to force fix file systems during boot

772

I have two disks, at / and /home/ and both show errors with e2fsck -fn /dev/<disk>. _{(-f = check even if 'clean', -n = read-only mode)}

How can I fix these file-system errors?

I managed to enable boot-time scanning (unsure if it scans both), but afterwards both disks still give errors.

Details

I followed the guide at https://linuxconfig.org/how-to-force-fsck-to-check-filesystem-after-system-reboot-on-linux and the method with the touch file didn't work even for the root disk. Ubuntu complains:

Feb 11 17:11:02 mark systemd-fsck[690]: Please pass 'fsck.mode=force' on the kernel command line rather than creating /forcefsck on the root file system.

I tried the second option on both disks, editing /etc/fstab to set the result code to 2 and executing tune2fs -c 1 /dev/disk for both disks. Since the, during every boot I see:

Press Ctrl+C to cancel all filesystem checks in progress
Checking in progress on 1 disk (26.0% completed)

It shows 1 disk (I expected two). ~~It starts at 26% and goes up to (almost) 100%.~~_{(it looked like that because the monitor was switching resolution)}

After logging in, when I execute e2fsck on both disks, I still find multiple errors, like orphaned inodes, wrong free node count, zero dtime inodes, block bitmap differences, etc.

How can I fix the errors I find with e2fsck, during boot-time?

The errors:

A mounted volume isn't "clean", this is absolutely normal. Only unmounted volumes (or volumes mounted read-only) are to be expected to be "clean". Most probably there isn't the slightest problem with your filesystems.

From the man page:

Note that in general it is not safe to run e2fsck on mounted filesystems. The only exception is if the -n option is specified, and -c, -l, or -L options are not specified. However, even if it is safe to do so, the results printed by e2fsck are not valid if the filesystem is mounted. If e2fsck asks whether or not you should check a filesystem which is mounted, the only correct answer is ``no''. Only experts who really know what they are doing should consider answering this question in any other way.

Check and fix your filesystem while booting from another medium (like a USB thumb drive). Checking the disks while they are mounted makes no sense at all and fsck output means nothing.

Easy:

Download Ubuntu again,
"burn" it to a USB / DVD / BlueRay
open a terminal and run:
```
fsck -vcf dev/<disk>
```
and press "y" for every error you want to fix.
Then locate bad blocks:
```
badblocks -v /dev/<disk>
```

If all goes well, all errors should be gone. If they're not, run:

smartctl --all /dev/<disk>

and that will then show you that your disk might be dying.
