Re: DC/OS dynamic reservation dosen't work

[haosdent]

Actually "unreserved" here in Marathon means Resources which don't
contains ReservationInfo. For static reservation, they didn't
contains ReservationInfo, so they are "unreserved". For dynamic
reservation, they have ReservationInfo, so they are "reserved". This is why
your task works in static reservation while could not work in dynamic
reservation.

Re: DC/OS dynamic reservation dosen't work

[caogaojin]

@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]

This may be a feature of Marathon. I saw it only filter resources from
those unreserved resources. After change

```
diff --git a/src/main/scala/mesosphere/mesos/TaskBuilder.scala
b/src/main/scala/mesosphere/mesos/TaskBuilder.scala
index efa3406..e750881 100644
--- a/src/main/scala/mesosphere/mesos/TaskBuilder.scala
+++ b/src/main/scala/mesosphere/mesos/TaskBuilder.scala
@@ -80,7 +80,7 @@ class TaskBuilder(app: AppDefinition,

 val resourceMatch =
   ResourceMatcher.matchResources(
-offer, app, runningTasks, ResourceSelector(acceptedResourceRoles,
reserved = false))
+offer, app, runningTasks, ResourceSelector(acceptedResourceRoles,
reserved = true))

 build(offer, resourceMatch)
   }
```

It would use the dynamic resources we reserved before. I find Marathon
document have these words:

```
### Static Reservations

Dynamic reservations can only be created for unreserved resources. If you
specify an agent's resources to be reserved for a role via the Mesos
`--resources` or `--default_role` flag, these resources cannot be used for
dynamic reservations. In addition, if Marathon is started with the
`--default_accepted_resource_roles` flag specifying a value that does not
contain `*`, your application definition should explicitly specify
`"acceptedResourceRoles": ["*"]` in order to allow usage and reservation of
unreserved cluster resources.
```

You could double check this with Marathon mailing list
https://groups.google.com/forum/?hl=en#!forum/marathon-framework . Thanks a
lot!

Re: DC/OS dynamic reservation dosen't work

[haosdent]

hmm, I am still digging more information in marathon. It may delay because
I am not familiar with marathon's code and sick today, but I would inform
you once have result. My quick conclusion is this may be the bug of
marathon when match resource requirement in offers from Mesos Master. Still
under finding the root cause of it.

@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

[caogaojin]

@Guangya, I tried with default_accepted_resource_roles option set to `dev`; 
same result, marathon can not start new tasks, waiting for resources.

@Guangya, @Haosdent, yes, on slave side, slave reports the resource consumed 
comes from `*` role;

while, on the master side, when curl http://10.132.46.71:5050/roles, it shows 
the resource comes from
`dev` role; 


```

moreover, when i reserve all resources(dynamic reservation) from default role

Re: DC/OS dynamic reservation dosen't work

[Guangya Liu]

Not sure if you need add a new parameter default_accepted_resource_roles ,
even if you start marathon with role dev, it can still get resources from
both role dev and *.

Please refer to
https://github.com/mesosphere/marathon/blob/master/docs/docs/command-line-flags.md
for marathon configuration.


   - v0.9.0 --default_accepted_resource_roles (Optional. Default: all
   roles): Default for the "acceptedResourceRoles"attribute as a
   comma-separated list of strings. All app definitions which do not specify
   this attribute explicitly use this value for launching new tasks. Examples:
   *, production,*, production

 Gaojin,

 Some questions and suggestions here:

 1) How did you deploy the nginx with new marathon URI? I did not found
 that I can configure the new marathon URI with nginx.

 2) Can you please send out the curl output for your master node:
 a) curl "http://master-ip:5050/master/slaves
 " 2>/dev/null|python -m json.tool


b) curl "http://master-ip:5050/master/state
 " 2>/dev/null|python -m json.tool


 3) For open source DC/OS issues, it is suggested to post your question
 to d...@help.io where you can always get instant and professional
 support.

 Thanks,

 Guangya

Re: DC/OS dynamic reservation dosen't work

roles  It shows consume "dev" in my side.

 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: { }
 }
 ]
 },

 

Re: DC/OS dynamic reservation dosen't work

[caogaojin]

@Haosdent, by the way, i’m using mesos:0.28.1, not the master branch. and 
marathon version is 1.1.1

Re: DC/OS dynamic reservation dosen't work

[caogaojin]

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.

Re: DC/OS dynamic reservation dosen't work

[haosdent]

Hi, @caogaoin. I try in with the master branch of Mesos and Marathon. And
it works fine for me.


```
INFO Finished processing dda04940-55b6-4ba7-a7bb-75c2108f3151-O8. Matched 1

```

Let me list my verify steps to help you find your problem when start your
tasks.

1. start Mesos master and agent, and reserve resources for dev.

```
$ ./bin/mesos-master.sh --work_dir=/tmp/mesos --ip=127.0.0.1
--hostname=127.0.0.1

$ ./bin/mesos-slave.sh --work_dir=/tmp/mesos --ip=127.0.0.1
--hostname=127.0.0.1 --master=127.0.0.1:5050


$ curl -i -d slaveId=dda04940-55b6-4ba7-a7bb-75c2108f3151-S0 \
-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://127.0.0.1:5050/reserve

2. start Marathon with dev role

```
./bin/start --master 127.0.0.1:5050 --zk zk://10.10.120.61:2181/marathon
--mesos_role dev
```

3. start task

```
$ cat task.json
{
"id": "/test-health",
"cmd": "sleep 200",
"cpus": 1.0,
"mem": 128.0
}

$ curl -X POST -H "Content-type: application/json"
http://127.0.0.1:8080/v2/apps -d @task.json
```

Sorry for make you confusing before. The offer looks match resource
requirement according to your log, let me reproduce it first.

Re: DC/OS dynamic reservation dosen't work

[Guangya Liu]

Gaojin,

Some questions and suggestions here:

1) How did you deploy the nginx with new marathon URI? I did not found that
I can configure the new marathon URI with nginx.

2) Can you please send out the curl output for your master node:
a) curl "http://master-ip:5050/master/slaves
" 2>/dev/null|python -m json.tool

   b) curl "http://master-ip:5050/master/state
" 2>/dev/null|python -m json.tool

3) For open source DC/OS issues, it is suggested to post your question to
d...@help.io where you can always get instant and professional support.

Thanks,

Guangya

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

Content-Length: 75

i’m using `dev` role in marathon.

Re: DC/OS dynamic reservation dosen't work

[haosdent]

And why you add

```
 "reservation": {}
```

in the resource define? Which role you used when start Marathon?

Re: DC/OS dynamic reservation dosen't work

[haosdent]

Why you send reserve request to http://10.132.46.81:5050/unreserve, is it
should be "http://10.132.46.81:5050/reserve;?

Re: DC/OS dynamic reservation dosen't work

[caogaojin]

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

[caogaojin]

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:

6328 end: 8079 } range { begin: 8082 end: 8180 } } role: "*" } resources {

"/slave(1)" }] 
(mesosphere.mesos.TaskBuilder:marathon-akka.actor.default-dispatcher-19)

can anyone help me with this?

thank you.
