Error: No space left on device

[esad ergül]

Hi all,

I am building a disk image (efi based x86_64 with grub) and root file system image with elbe tool. Then I create a swu image with rootfs image. ( SWUpdate: syntax and tags with the default parser — Embedded Software Update Documentation 2021.11 documentation (sbabic.github.io)  ) When I do an update I always get the error that there is no space available, although there is enough space on the second rootfs partition (sda5). 

software = {
    version = "0.1.0";
    hardware-compatibility = ["Demo","1.0"];

    rootfs: {
        copy1: {
            images: ({
                filename = "root.img.tar.gz";
                device = "/dev/sda3";
                compressed = "zlib";
                installed-directly = true;
                type = "raw";
                sha256 = "807797c6f3e80c3abb3298973d28b7929d3d3011f8be643107728ee0df0761f9";
            });
            -------------------
        };
        copy2: {
            images: ({
                filename = "root.img.tar.gz";
                device = "/dev/sda5";
                compressed = "zlib";
                installed-directly = true;
                type = "raw";
                sha256 = "807797c6f3e80c3abb3298973d28b7929d3d3011f8be643107728ee0df0761f9";
            });
          ---------------
        };
    };
};

If I write the root.img file directly with dd command to second rootfs partition, it works and the system can be booted from second rootfs (if I set bootloader variables manually and reboot the device).

I would be very happy if someone could give me a hint how to fix this error.

Sorry, I found my mistake, I created the second rootfs partition with parted in MB. Therefore some bytes were missing. I calculated the partition size in bytes and then created the partiiton. Then it worked.

Best regards
