Re: DC/OS dynamic reservation dosen't work
@Haosdent, sorry for delay; i’m not familiar with scala, the compilation takes
me some time. you are right, after changing the file you told me, it works. But
that’s not what i want, it my situation, marathon should takes both reserved
resource and unreserved resource; when using official marathon version,
marathon will use static reserved resources (mesos agent started with
`--default_role dev` flag, and marathon with `--mesos_role dev`), but it seems
marathon did not take static reserved resource as *reserved resource*,
```
Considering unreserved resources with roles {dev}. Not all basic resources
satisfied: cpus NOT SATISFIED (1.0 > 0.0), mem NOT SATISFIED (128.0 > 0.0)
(mesosphere.mesos.ResourceMatcher$:marathon-akka.actor.default-dispatcher-6)
```
the above shows that marathon only considers *unreserved* resources with role
`dev`. However IMO, all resources with role `dev` should be reserved resources,
right? i’m quite confused, @haosdent, are resources provided by mesos agent
that started with `--default_role dev` flag unreseved resources? i will advise
mesosphere/marathon community for more help.
Thanks,

Re: DC/OS dynamic reservation dosen't work
@Haosdent, what does http://10.132.46.71:5050/roles mean? shouldn’t that tell
us all resources that framework with `dev` role takes, both from `dev` and `*`
role? It doesn’t mean resources are consumed from `dev` role, right?

Re: DC/OS dynamic reservation dosen't work
"resources": {
"cpus": 0,
"disk": 0,
"mem": 0
},
"weight": 1.0
},
{
"frameworks": [
"439a851d-aa09-47af-bc68-d5588dc9f5da-0002"
],
"name": "dev",
"resources": {

"disk": 0,
"mem": 128.0,
"ports": "[31994-31994]"
},
"weight": 1.0
}
]
}
```
moreover, when i reserve all resources(dynamic reservation) from default role
to `dev` role, not a single task can start on that slave, either declaring use
`dev` resource or `*` resource.
```
"reserved_resources": {
"dev": {
"cpus": 4.0,
"disk": 0.0,
"mem": 6727.0
}
},
"reserved_resources_full": {
"dev": [
{

"reservation": {},
"role": "dev",
"scalar": {
"value": 6727.0
},
"type": "SCALAR"
},
{
"name": "cpus",
"reservation": {},
"role": "dev",
"scalar": {
"value": 4.0
},
"type": "SCALAR"
}
]
},
"resources": {
"cpus": 4.0,
"disk": 46055.0,
"mem": 6727.0,
"ports": "[31000-32000]"
},
"unreserved_resources": {
"cpus": 0.0,
"disk": 46055.0,
"mem": 0.0,

```
@Haosdent, can u post your master:5050/slaves? i think this should be the issue.

Re: DC/OS dynamic reservation dosen't work
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.

my bad; actually i use http://10.132.46.81:5050/reserve for reservation, and
http://10.132.46.81:5050/unreserve
for releasing resources :)

if i do not add this, mesos will report error:
```
HTTP/1.1 400 Bad Request

Re: DC/OS dynamic reservation dosen't work
Anyone has such experiences? I think it may be a dynamic reservation issue.
In my situation, i turn off mesos authentication mechanism, will this be a
problem?

DC/OS dynamic reservation dosen't work
Hi list,
I’m currently using dynamic reservation mechanism with mesosphere/DCOS 1.7, the
opensourced version,
and something wired just happened. I tried to setup a new marathon service from
the universe repo,
and i did a slight modification, setting mesos_role to `dev`. i also turned off
mesos anthentication
mechenism.
My steps are:
First i tried to reserve 2 cpu and 1743 ram to `dev` role using http endpoint,
and it works:
# curl -i -d slaveId=e6d590b1-5f2d-4be9-93fd-2fac364584cf-S11 \
-d resources='[
{
"name": "cpus",
"type": "SCALAR",
"scalar": {
"value": 2.0
},
"role": "dev",
"reservation": {
}
},
{
"name": "mem",
"type": "SCALAR",
"scalar": {
"value": 1024.0
},
"role": "dev",
"reservation": {
}
}
]' -X POST http://10.132.46.81:5050/unreserve
Second, the slave shows following infomation:
# curl http://10.132.46.81/mesos/slaves
reserved_resources_full: {
dev: [
{
name: "cpus",
type: "SCALAR",
scalar: {
value: 2
},
role: "dev",
reservation: { }
},
{
name: "mem",
type: "SCALAR",
scalar: {
value: 1743
},
role: "dev",
reservation: { }
}
]
},
Third, i tried to run nginx using the new marathon service, which i also set
the task only accept `dev` resources,
ID: /nginx
...
Resource Roles: dev
4. on marathon ui i just see the waiting status, which means there’s no
suitable resource offer, marathon reports:
Insufficient resources for [/nginx] (need cpus=1.0, mem=128.0, disk=0.0,
ports=(1 dynamic), available in offer: [id { value:
"e6d590b1-5f2d-4be9-93fd-2fac364584cf-O7476" } framework_id { value:
