A disk check of one filesystem failed on boot Ubuntu Server 22.04.5 LTS

After removing (commenting) that item from the fstab file and booting normally I ran fsck against that i.e. /dev/sdg1 in this case with the following messages:

/dev/sdg1 has unsupported feature(s): FEATURE_C12

DATABACKUP.BACKU ***** WARNING: FILESYSTEM STILL HAS ERRORS


I booted the same computer from a thumb drive with Ubuntu Desktop 24 and ran fsck -vf against the same file system i.e. /dev/sdg1 without errors.

I removed the disk from the external drive bay, connected it to my Fedora 39 desktop, ran the same thing fsck -vf without errors

I.E. two newer versions of fsck in util-linux did not throw errors

Also ran smartmontools long test without errors

At this point i figured there is nothing wrong with the drive or the filesystem

I edited the grub configuration file to allow the system to skip the file system boot check but I wasn't happy with that.

I looked online and found the following fix:

Booting from Ubuntu Desktop 24 live usb again I ran

tune2fs -O ^orphan_file /dev/sdg1

then update-grub

I uncommented the fs in question from the fstab file, rebooted, and the boot finished without errors.

Q.E.D.
