Can't mount an ext4 partition under NetBSD

[Marietto2008]

Hello to everyone.

I'm trying to mount an ext4 partition on NetBSD. This is the NetBSD version that I'm running right now :

localhost# uname -a

NetBSD localhost 9.2 NetBSD 9.2 (GENERIC) #0: Wed May 12 13:15:55 UTC 2021  [email protected]:/usr/src/sys/arch/amd64/compile/GENERIC amd64

The disk that I have previously formatted with the ext4 partition and that I want to mount is : WD, 2500BMV External, 1.05 and it is mapped as sd1 and sd2 :

    localhost# dmesg | grep 2500

    [     2.435070] sd2 at scsibus2 target 0 lun 0: <WD, 2500BMV External, 1.05> disk fixed
    [     3.356209] sd1 at scsibus1 target 0 lun 0: <WD, 2500BMV External, 1.05> disk fixed

    localhost# gpt show sd1

          start       size  index  contents

              1          1         Pri GPT header
              2         32         Pri GPT table
             34       2014         Unused
           2048  488394752      1  GPT part - Linux data

      488397135         32         Sec GPT table
      488397167          1         Sec GPT header

but sd2 is another disk :

    localhost# gpt show sd2

        start         size  index  contents
            0            1         PMBR
            1            1         Pri GPT header
            2           32         Pri GPT table
           34         2014         Unused

  23437705215            1         Sec GPT header

But let's see what says dmesg :

    localhost# dmesg | grep sd1

It seems that there are two different wench to mount,dk16 and dk10. Let's try to mount both of them :

    localhost# fuse-ext2 /dev/dk16 /mnt/WD2500BMV -o rw+
    localhost# ls /mnt/WD2500BMV
    nothing.

    localhost# fuse-ext2 /dev/dk10 /mnt/WD2500BMV -o rw+
    localhost# ls /mnt/WD2500BMV
    nothing.

None of them is the working one.
