# Getting “no space left on device” errors with Boot2Docker?
|
2014-08-23 00:06:28 +00:00

If you're using Boot2Docker with a large number of images, or the images you're
|
|
|
|
|
working with are very large, your pulls might start failing with "no space left
|
|
|
|
|
on device" errors when the Boot2Docker volume fills up. The solution is to
|
|
|
|
|
increase the volume size by first cloning it, then resizing it using a disk
|
|
|
|
|
partitioning tool.

|
|
|
|
We recommend [GParted](http://gparted.sourceforge.net/download.php/index.php).
|
|
|
|
|
The tool comes as a bootable ISO, is a free download, and works well with
|
|
|
|
|
VirtualBox.

## 1. Stop Boot2Docker
|
2014-08-23 00:06:28 +00:00
|
|
|
|
|
2014-08-25 23:50:55 +00:00
|
|
|
|
Issue the command to stop the Boot2Docker VM on the command line:
|
2014-08-23 00:06:28 +00:00
|
|
|
|
|
2014-08-27 18:49:26 +00:00
|
|
|
|
`$ boot2docker stop`
|
2014-08-23 00:06:28 +00:00
|
|
|
|
|
2014-08-23 01:19:58 +00:00
|
|
|
|
## 2. Clone the VMDK image to a VDI image
|
2014-08-23 00:06:28 +00:00
|
|
|
|
|
2014-08-28 18:04:53 +00:00
|
|
|
|
Boot2Docker ships with a VMDK image, which can’t be resized by VirtualBox’s
|
|
|
|
|
native tools. We will instead create a VDI volume and clone the VMDK volume to
|
|
|
|
|
it.
|
2014-08-25 23:50:55 +00:00
|
|
|
|
|
2014-08-23 01:19:58 +00:00
|
|
|
|
Using the command line VirtualBox tools, clone the VMDK image to a VDI image:
|
2014-08-23 00:06:28 +00:00
|
|
|
|
|
2014-08-27 18:49:26 +00:00
|
|
|
|
`$ vboxmanage clonehd /full/path/to/boot2docker-hd.vmdk /full/path/to/<newVDIimage>.vdi -—format VDI -—variant Standard`
|
2014-08-23 00:06:28 +00:00
|
|
|
|
|
2014-08-26 21:01:10 +00:00
|
|
|
|
## 3. Resize the VDI volume
|
2014-08-23 00:06:28 +00:00
|
|
|
|
|
2014-08-28 18:04:53 +00:00
|
|
|
|
Choose a size that will be appropriate for your needs. If you’re spinning up a
|
|
|
|
|
lot of containers, or your containers are particularly large, larger will be
|
|
|
|
|
better:
|
2014-08-23 00:06:28 +00:00
|
|
|
|
|
2014-08-27 18:49:26 +00:00
|
|
|
|
`$ vboxmanage modifyhd /full/path/to/<newVDIimage>.vdi —-resize <size in MB>`
|
2014-08-23 00:06:28 +00:00
|
|
|
|
|
2014-08-23 01:19:58 +00:00
|
|
|
|
## 4. Download a disk partitioning tool ISO
|
2014-08-23 00:06:28 +00:00
|
|
|
|
|
2014-08-27 18:49:26 +00:00
|
|
|
|
To resize the volume, we'll use [GParted](http://gparted.sourceforge.net/download.php/).
|
2014-08-25 23:50:55 +00:00
|
|
|
|
Once you've downloaded the tool, add the ISO to the Boot2Docker VM’s IDE bus.
|
2014-08-28 18:04:53 +00:00
|
|
|
|
You might need to create the bus before you can add the ISO.
|
|
|
|
|
|
|
|
|
|
**Note:**
|
|
|
|
|
It's important that you choose a partitioning tool that is available as an ISO so
|
|
|
|
|
that the Boot2Docker VM can be booted with it.

## 5. Add the new VDI image

|
|
|
|
|
2014-08-28 18:04:53 +00:00
|
|
|
|
In the settings for the Boot2Docker image in VirtualBox, remove the VMDK image
|
|
|
|
|
from the SATA contoller and add the VDI image.
|

## 6. Verify the boot order
|
|
|
|
|
|
2014-08-28 18:04:53 +00:00
|
|
|
|
In the **System** settings for the Boot2Docker VM, make sure that **CD/DVD** is
|
|
|
|
|
at the top of the **Boot Order** list.

## 7. Boot to the disk partitioning ISO
|
|
|
|
|
|
2014-08-28 18:04:53 +00:00
|
|
|
|
Manually start the Boot2Docker VM in VirtualBox, and the disk partitioning ISO
|
|
|
|
|
should start up. Using GParted, choose the **GParted Live (default settings)**
|
|
|
|
|
option. Choose the default keyboard, language, and XWindows settings, and the
|
|
|
|
|
GParted tool will start up and display the VDI volume you created. Right click
|
|
|
|
|
on the VDI and choose **Resize/Move**.
|

|
|
|
|
|
|
2014-08-28 18:04:53 +00:00
|
|
|
|
Drag the slider representing the volume to the maximum available size, click
|
|
|
|
|
**Resize/Move**, and then **Apply**.
|
2014-08-25 23:50:55 +00:00
|
|

|
|
|
|
|
|
2014-08-28 18:04:53 +00:00
|
|
|
|
Quit GParted and shut down the VM. Remove the GParted ISO from the IDE controller
|
|
|
|
|
for the Boot2Docker VM in VirtualBox.
|
2014-08-23 01:19:58 +00:00

|
|
## 8. Start the Boot2Docker VM
|
|
|
|
|
|
2014-08-28 18:04:53 +00:00
|
|
|
|
Fire up the Boot2Docker VM manually in VirtualBox. The VM should log in
|
|
|
|
|
automatically, but if it doesn't, the credentials are `docker/tcuser`. Using
|
|
|
|
|
the `df -h` command, verify that your changes took effect.
