What did I do wrong?

Where did that "repair" thing come from?  The flag you're setting is called "force_fsck".

Tune2fs Force FSCK Repair

The tune2fs command is used to modify the filesystem mount options and settings for ext2, ext3, and ext4 file systems. The option -E force_fsck enables forced filesystem checks (fsck) on every reboot, while the repair option specifies that fsck should attempt to automatically repair any issues found during the check.

AI answers... Apparently I got a slightly different one than you.
"The repair part of the command is not a separate option, but rather a concept."

In an earlier message you said "it did run".  What was "it" that took 10 seconds?

fsck ran at boot, but only took about 10 seconds for a
1TB drive.  I am doubtful it tried tp do a repair.

If it found something, it would have repaired it or indicated a problem.

That command just sets the flag.  You either need to reboot or remount the filesystem after setting it.  Although if you can unmount it, then you don't need to set the flag.  You could just run "e2fsck" directly.


It is my / partition.  I suppose I could run a live usb and do
a repair from there?

I would recommend that if you are doubting the current situation.

I am not having any luck finding for to tell e2fsck I want a
repair too.

Because there is no distinction.  That flag marks the filesystem as having errors, so it needs to be checked when mounted.  However, I'm not sure that the mounting fsck is as thorough as a manually run one.  I actually think that if it finds any non-trivial issue that it will just fail the mount.  So do try that live boot.



Thank you!   I was over thinking it.
If you are mounting your partitions via fstab, for the last 2 parameters on your mount definition you can specify 0 1 for the root partition and 0 2 for all other partitions. The 0 specifies to not dump the volume the 1 or 2 specifies to do an fsck at mount time. The man page says to specify 1 for the root volume and 2 for all other volume to utilise hardware parallelism if available, also with 1 specified for the root volume that will be checked first.

regards,
Steve
