Hi @Haosdent, i have done your steps, yes, it works; But marathon does not
cosume `dev` resources,
it uses default role resource instead:
```
# curl 10.132.46.71:5050/slaves | python -m json.tool
"used_resources_full": [
{
"name": "cpus",
"role": "*",
"scalar": {
"value": 1.0
},
"type": "SCALAR"
},
{
"name": "mem",
"role": "*",
"scalar": {
"value": 128.0
},
"type": "SCALAR"
},
{
"name": "ports",
"ranges": {
"range": [
{
"begin": 31967,
"end": 31967
}
]
},
"role": "*",
"type": "RANGES"
}
],
"version": "0.28.1"
```
@Guangya, so it should not be A DC/OS issue, it related to mesos, or maybe
marathon.
