Instead of using traditional way of building the rootfs of every stage in
|
||||
single subdirectories and copying over the previous one to the next one,
|
||||
qcow2 based virtual disks with backing images are used in every stage.
|
||||
This speeds up the build process and reduces overall space consumption
|
||||
significantly.
|
||||
|
||||
<u>Additional optional parameters regarding qcow2 build:</u>
|
||||
|
||||
* `BASE_QCOW2_SIZE` (Default: 12G)
|
||||
|
||||
Size of the virtual qcow2 disk.
|
||||
Note: it will not actually use that much of space at once but defines the
|
||||
maximum size of the virtual disk. If you change the build process by adding
|
||||
a lot of bigger packages or additional build stages, it can be necessary to
|
||||
increase the value because the virtual disk can run out of space like a normal
|
||||
hard drive would.
|
||||
|
||||
**CAUTION:** Although the qcow2 build mechanism will run fine inside Docker, it can happen
|
||||
that the network block device is not disconnected correctly after the Docker process has

ended abnormally. In that case see [Disconnect an image if something went wrong](#Disconnect-an-image-if-something-went-wrong)

# Regarding Qcow2 image building
|
||||
|
||||
### Get infos about the image in use
|
||||
|
||||
If you issue the two commands shown in the example below in a second command shell while a build
|
||||
is running you can find out, which network block device is currently being used and which qcow2 image
|
||||
is bound to it.
|
||||
|
||||
Example:
|
||||
|
||||
```bash
|
||||
root@build-machine:~/$ lsblk | grep nbd
|
||||
nbd1 43:32 0 10G 0 disk
|
||||
├─nbd1p1 43:33 0 10G 0 part
|
||||
└─nbd1p1 253:0 0 10G 0 part
|
||||
|
||||
root@build-machine:~/$ ps xa | grep qemu-nbd
|
||||
2392 pts/6 S+ 0:00 grep --color=auto qemu-nbd
|
||||
31294 ? Ssl 0:12 qemu-nbd --discard=unmap -c /dev/nbd1 image-stage4.qcow2
|
||||
```
|
||||
|
||||
Here you can see, that the qcow2 image `image-stage4.qcow2` is currently connected to `/dev/nbd1` with
|
||||
the associated partition map `/dev/mapper/nbd1p1`. Don't worry that `lsblk` shows two entries. It is totally fine, because the device map is accessible via `/dev/mapper/nbd1p1` and also via `/dev/dm-0`. This is all part of the device mapper functionality of the kernel. See `dmsetup` for further information.
|
||||
|
||||
### Mount a qcow2 image
|
||||
|
||||
If you want to examine the content of a a single stage, you can simply mount the qcow2 image found in the `WORK_DIR` directory with the tool `./imagetool.sh`.
|
||||
|
||||
See `./imagetool.sh -h` for further details on how to use it.
|
||||
|
||||
### Disconnect an image if something went wrong
|
||||
|
||||
It can happen, that your build stops in case of an error. Normally `./build.sh` should handle image disconnection appropriately, but in rare cases, especially during a Docker build, this may not work as expected. If that happens, starting a new build will fail and you may have to disconnect the image and/or device yourself.
|
||||
|
||||
A typical message indicating that there are some orphaned device mapper entries is this:
|
||||
|
||||
```
|
||||
Failed to set NBD socket
|
||||
Disconnect client, due to: Unexpected end-of-file before all bytes were read
|
||||
```
|
||||
|
||||
If that happens go through the following steps:
|
||||
|
||||
1. First, check if the image is somehow mounted to a directory entry and umount it as you would any other block device, like i.e. a hard disk or USB stick.
|
||||
|
||||
2. Second, to disconnect an image from `qemu-nbd`, the QEMU Disk Network Block Device Server, issue the following command (be sure to change the device name to the one actually used):
|
||||
|
||||
```bash
|
||||
sudo qemu-nbd -d /dev/nbd1
|
||||
```
|
||||
|
||||
Note: if you use Docker build, normally no active `qemu-nbd` process exists anymore as it will be terminated when the Docker container stops.
|
||||
|
||||
3. To disconnect a device partition map from the network block device, execute:
|
||||
|
||||
```bash
|
||||
sudo kpartx -d /dev/nbd1
|
||||
or
|
||||
sudo ./imagetool.sh --cleanup
|
||||
```
|
||||
|
||||
Note: The `imagetool.sh` command will cleanup any /dev/nbdX that is not connected to a running `qemu-nbd` daemon. Be careful if you use network block devices for other tasks utilizing NBDs on your build machine as well.
|
||||
|
||||
Now you should be able to start a new build without running into troubles again. Most of the time, especially when using Docker build, you will only need no. 3 to get everything up and running again.
