https://bugzilla.suse.com/show_bug.cgi?id=1216110 Bug ID: 1216110 Summary: fsck fails with FEATURE_C12 as does e2fsck Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: x86-64 OS: openSUSE Leap 15.5 Status: NEW Severity: Critical Priority: P5 - None Component: Other Assignee: screening-team-bugs@suse.de Reporter: llrainey15@gmail.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- fsck / e2fsck is downlevel to gparted created ext4 file systems. There is a new feature C12 for "orphan files", whatever that is, that gparted added to newly created the ext4 file system. I added a mount to /etc/fstab and it failed to fsck I had to change the 2 to 0 to get past the failure. The file on /dev/nvme1n1p1 was created by gparted, it was mounted and files copied to it and entry added to /etc/fstab. Here is the cause: LLR5:~ # e2fsck -f /dev/nvme1n1p1 e2fsck 1.46.4 (18-Aug-2021) /dev/nvme1n1p1 has unsupported feature(s): FEATURE_C12 e2fsck: Get a newer version of e2fsck!
