Quick How To: Installing to USB stick and/or migrate to a USB stick avoid 'Failed to partition selected disk' error

  • I hope this helps someone else...

    OMV installer attempts to create a swap partition equal to the amount of system ram by default. If ram>available space, the installer fails.

    Work arounds:

    -Pull out all but minimum system ram

    OMV doesn't need much disk space and I have a bunch of smaller unused USB sticks lying around (8gb) BUUUT my minimum ram configuration is 8gb.

    -Load Deb then build/load OMV

    Original thread I found suggested netinst img.

    -My method: Install on a sufficiently larger USB stick then transfer partition to smaller stick (I have 64gb ram so I used a 128gb stick)

    1. Install as per usual onto larger stick
    2. load OMV extras/ramdisk plugin, restart / verify operation (swap partition should show as 'unmounted')
    3. burn GParted image to CD or USB stick and boot (make sure you grab amd-64 image)
    4. resize data partition to fit smaller USB stick (overprovision a bit, ie 7.25gb on 8gb stick, many reasons for this)
    5. delete any existing partitions on smaller stick
    6. copy data partition from larger stick onto smaller stick
    7. after these operations have completed, add the 'boot' flag to the newly transferred partition
    8. test functionality - this may not always be the case but I had to install bootloader as well
      1. guide for bootloader here (Restoring GRUB 2 Boot Loader)
    9. repeat procedure on a third stick... Might as well make a backup (or 3) while you are at it.

    This method should also work for migrating from a disk install > USB or spinner>ssd etc.
