fsck "FEATURE_C12"?

I have a data partition on the same ssd as the bootable systems. If I do this in Suser Slowroll for example

# fsck /dev/sda10
fsck from util-linux 2.39.3
e2fsck 1.47.0 (5-Feb-2023)
/dev/sda10: clean, 16610/18022400 files, 63630170/72089600 blocks

This partition is normally automounted in fstab with a "nofail" switch

# /etc/fstab: static file system information Devuan on p12.
UUID=f203d9ec-a53c-4f33-ad2a-222cf8f8dbcd     /        ext4    errors=remount-ro 0  1
UUID=7de3fe4d-f350-4661-adf4-0159abacf3ff     swap     swap    sw,nofail         0  0
UUID=95cb7a9a-d7f2-4fb8-bf49-56828acf931c     /0/adat  ext4    defaults,nofail   0  2
UUID=2b43042f-761c-40ec-b207-5af655a51b93     /0/local ext4    defaults,nofail   0  2

So I would have presumed that inability to mount it would never fail the boot.

BUT...  when I try to boot Devuan the boot does at least stumble with a boot halt and the advisory to continue with a Cntrl-D. Subsequent check gives this:

# fsck -f /dev/sda10
fsck from util-linux 2.36.1
e2fsck 1.46.2 (28-Feb-2021)
/dev/sda10 has unsupported feature(s): FEATURE_C12
e2fsck: Get a newer version of e2fsck!

This Devuan partition is up to date (I think). It's not a federal case, I can live with it, just thought I'd mention it for the devs. As it is the data partition is unmounted while booted into Devuan (I have not tried manually mounting it).

Re: fsck "FEATURE_C12"?

didn't work for my problem, I tried from another booted system. I think the ultimate fix is an update of fsck, like the error message says..

Latest version of E2fsprogs

If possible, it is better to use a live gparted session for such work

I have something back in my mind that this problem maybe due to generating the file system with a brandnew kernel, and then trying to use it on an older distribution.

Re: fsck "FEATURE_C12"?

it was probably formatted with bleeding-edge tumbleweed but it serves as a data partition for six or seven different systems

Re: fsck "FEATURE_C12"?

Well, a fix could be to reformat it with the oldest distro that needs to access that partition.
