> Mesos Executor UI - Disk:Used Field isn't populated with Docker Container
> Runtime
> ---------------------------------------------------------------------------------
>
> Key: MESOS-7894
> URL: https://issues.apache.org/jira/browse/MESOS-7894
> Project: Mesos
> Issue Type: Bug
> Affects Versions: 1.2.2
> Environment: DC/OS 1.9.2 (CentOS 7.3, Docker 1.13.1, Mesos 1.2.2,
> Marathon 1.4.5)
> Reporter: Justin Lee
> Priority: Minor
> Attachments: UCR on left, Docker on right.png

> If you use the Docker container runtime, the 'Disk' 'Used' field never gets
> populated in the Mesos UI (on the executor/task page).
> Steps to Reproduce:
> in DC/OS 1.9.2, deploy two apps:
> {code:javascript}
> {
> "id": "/dummy-disk-docker",
> "cmd": "dd if=/dev/zero of=$MESOS_SANDBOX/testfile bs=128M count=1; tail -f
> /dev/null",
> "instances": 1,
> "cpus": 0.1,
> "mem": 256,
> "disk": 150,
> "container": {
> "type": "DOCKER",
> "docker": {
> "image": "alpine"
> }
> }
> }
> {code}
> {code:javascript}
> {
> "id": "/dummy-disk-ucr",
> "cmd": "dd if=/dev/zero of=$MESOS_SANDBOX/testfile bs=128M count=1; tail -f
> /dev/null",
> "instances": 1,
> "cpus": 0.1,
> "mem": 256,
> "disk": 150,
> "container": {
> "type": "MESOS"
> "docker": {
> "image": "alpine"
> }
> }
> }
> {code}
> Wait for them the deploy.
> Then, navigate to the mesos UI, and go to the executor/task page for the two
> tasks.
> On the UCR task, eventually the "Used Disk" field should populate with 128 MB
> (the size of the dummy file).
> The same field on the Docker task will never get populated.
> Both containers are writing to the same location on the agent filesystem
> (/var/lib/mesos/slave/slaves/<slave-id>/frameworks/<framework-id>/executors/<executor-id>/runs/latest,
> but only one reports the data through the UI.
