            Bug ID: 271105
           Summary: ext2fs cant mount disks with 4k native sector size
           Product: Base System
           Version: 13.2-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: k@vodka.home.kg

mount -t ext2fs /dev/nvd0p3 /mnt/linux
mount: /dev/nvd0p3: Invalid argument

It worked well until I moved linux parftition to nvme disk with 4K native
sector size. nvme's usually can be formatted with either 512 or 4096 sector
size. by default they come with 512 sector size.

tune2fs, e2fsck from BSD work well. linux mounts this partition without any
I can successfully mount msdos and ntfs partitions from that drive in FreeBSD

Googling this case I found someone experiencing same bug with a 4k native disk
