can not instal ext4 -- want to use USB as root



  • I'm trying to mount my USB drive as root. I started following the instructions at https://wiki.onion.io/Tutorials/Using-USB-Storage-as-Rootfs and got as far as trying to install kmod-fs-ext4, and got the following error:

    **root@Omega-9C9A:/# opkg install kmod-fs-ext4
    Upgrading kmod-fs-ext4 on root from 4.4.46-1 to 4.4.74-1...
    Downloading http://repo.onion.io/omega2/packages/core/kmod-fs-ext4_4.4.74-1_mipsel_24kc.ipk
    Collected errors:

    • satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-fs-ext4:
    • kernel (= 4.4.74-1-97eec485b1ee24d5b1ca0357d1dd7304) 
      
    • opkg_install_cmd: Cannot install package kmod-fs-ext4.**

    The kernel is not 4.4.74, it's 4.4.46 ....

    root@Omega-9C9A:/# uname -r
    4.4.46

    However, the settings tells me I'm uptodate with the firmware.

    Any ideas how I get around this?



  • Solution was already given in http://community.onion.io/topic/1139/omega2-cannot-install-kmod-fs-ext4-kmod-usb-storage-extra-kernel-version-mismatch :

    wget http://repo.onion.io/omega2/packages/core/kmod-fs-ext4_4.46-1_mipsel_24kc.ipk
    opkg install kmod-fs-ext4_4.4.46-1_mipsel_24kc.ipk --nodeps
    


  • thx!!! Must have missed that one



  • @Maximilian-Gerhardt Spoke too soon, didn't work. It installs just fine. Or it seems to. After I've done the install (and double checked it) and rebooted, uname still shows the version as 4.4.46 and I can not install the fs-ext4 package

  • @david-silver I have definitely verified this to be working on my own Omega2+ a few weeks ago using it to boot from a 16GB microSD card. I just noticed that you have linked to the old wiki domain, which is for the Omega (1), but you do have a Omega2(+), right? The above commands should be all you need to install it, you should then be able to use commands like mkfs.ext4 /dev/sda1 (see: https://docs.onion.io/omega2-docs/boot-from-external-storage.html for booting from USB or microSD). Do not try to install the newest (4.47-1) via the repositories, just force the installation of the downloaded 4.46-1 package as instructed above and use it. Also the installation of that module does not upgrade your kernel version! It just forces the package to install on a non-matching kernel version. If I misunderstood anything, please let me know.



  • @Maximilian-Gerhardt I realised my error about not downloading the kernel itself (and did consider upgrading the kernel but chickened out),

    yes I do have an onion 2. However, I don't know what you mean by the omega 1 wiki vs the omega 2 wiki. I just following the links in the documentation or on here.

    Following the link in your reply seems to go to a different place, but the same instructions.

    I tried installing all of kmod-fext4, kmod-usb-storage-extras and and kmod-e2f-sprogs all with --nodep but the last one would not install so I could not get any further



  • @david-silver error message:

    Collected errors:

    • opkg_install_cmd: Cannot install package ef2sprogs.
    • pkg_run_script: package "kmod-usb-storage-extras" postinst script returned status 255.
    • opkg_configure: kmod-usb-storage-extras.postinst returned 255.


  • @david-silver Ah, now I see your point. The package kmod-usb-storage gives the same type of error as kmod-fs-ext4.. I never noticed that error because I did microSD card install, so I didn't even try to install that package. I also tried to install it using the --nodeps method and a manual download, but I get hung up on the same error..

    # remove any old installations you might have
    opkg remove kmod-usb-storage
    # download latest repos
    opkg update
    #install e2fsprogs (throws no error)
    opkg install e2fsprogs 
    # manually install the correct package for kmod-fs-ext4 (skip if you already have this one)
    wget http://repo.onion.io/omega2/packages/core/kmod-fs-ext4_4.46-1_mipsel_24kc.ipk

     * opkg_configure: kmod-usb-storage-extras.postinst returned 255.
    

    The error is due to the post-install script trying to modprobe all the modules, but as you can see all of them are already loaded, thus the used insert_modules command will return an "error" making the post-installation fail. You can fix it by editing the file /usr/lib/opkg/info/kmod-usb-storage-extras.postinst-pkg to:

    #!/bin/sh
    [ -z "$IPKG_INSTROOT" ] || exit 0
    . /lib/functions.sh
    insert_modules ums-alauda ums-cypress ums-datafab ums-freecom ums-isd200 ums-jumpshot ums-karma ums-sddr09 ums-sddr55 ums-usbat
    #force clean exit code (0)
    exit 0
    

    You should then get

    root@Omega-17FD:~# opkg configure kmod-usb-storage-extras
    Configuring kmod-usb-storage-extras.
    ums-alauda is already loaded
    ums-cypress is already loaded

    ums-sddr09 is already loaded
    ums-sddr55 is already loaded
    ums-usbat is already loaded
    root@Omega-17FD:~#
    

    Ofcourse I don't know whether it actually fixes the problem - it just forces the installation to go through. You have to see yourself if you can get it to boot from the USB stick then, but now all the tools should be in place so that you can follow the Omega2 documentation I posted above. BTW: The https://wiki.onion.io website is for the old Omega, not the new Omega2, that's what I meant. If you have an Omega2 or Omega2+, you need to follow the instructions I posted above.



  • thanks, that worked!

    I didn't get exactly the same output spew, and the diskcheck spew looks a little odd, however, it did work and I can use the differences as a learning event.

    thx for your help.
