Docker拉错误：设备上没有剩余空间

Question

While doing a docker pull I get this error message

Handler for POST /images/create returned error: ApplyLayer exit status 1 stdout: stderr: write XXXX: no space left on device

I checked the disk space and the Inodes and I have enough of them. I tried anyway to free some additional space and inodes. Despite this the error falls always on the same file (which rules out a potential space problem).

The image to pull is ~12Gb

Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda4
3,0M 295K 2,7M 10% /

Filesystem Size Used Avail Use% Mounted on /dev/sda4
47G 15G 30G 34% /

I tried exporting the image from another computer and importing it on the computer causing problems. However I get the same error of 'no space left on device'

I tried removing all images, even deleting completely /var/lib/docker, restarting the docker daemon, without any luck.

Running on MacBook 12.11 with ubuntu 14.02 installed.

Answer 1

devicemapper has caused me innumerable problems across various different kernels and OSs. Issues here .

Jerome Petazzo has some broader recommendations - although BTRFS also had/has ongoing serious issues, that has got it (and DeviceMapper, and AUFS on Ubuntu 12.04) pulled from production in previous deployments.

My preference for storage drivers is overlay , which is available since kernel 3.18 (further opinions expressed here ):

Storage Driver: overlay
 Backing Filesystem: extfs

Update /etc/default/docker with ( more here ):

DOCKER_OPTS="-s overlay"

(ensure you only have one DOCKER_OPTS - that file doesn't support BASH syntax as one may expect)

edit: I seem to recall the devicemapper fix is to delete everything as you have done, and reboot.
