Fair sharing not working

Open Sharathmk99 opened this issue 3 years ago • 24 comments

What happened: My cluster has total 11 CPU. I'm trying to create 2 queue(excluding default queue) with weight 5 for each queue. Queue manifest,

apiVersion: scheduling.volcano.sh/v1beta1
kind: Queue
metadata:
  name: test
spec:
  weight: 5

---

apiVersion: scheduling.volcano.sh/v1beta1
kind: Queue
metadata:
  name: test1
spec:
  weight: 5

Queue List,

Name                     Weight  State   Inqueue Pending Running Unknown
default                  1       Open    0       0       0       0
test                     5       Open    0       0       0       0
test1                    5       Open    0       0       0       0

Created 3 Jobs for test queue with CPU resource as follow, job1 -> CPU 5 job2 -> CPU 5 job3 -> CPU 1

Now all 3 jobs are running and utilizing full cluster.

Now i'm creating new Job in test1 queue with CPU 2. I'm expecting 1 Job will be evicted from test queue and Job in test1 queue will be running. But Job in test1 queue is in Inqueue state.

Name                     Weight  State   Inqueue Pending Running Unknown
default                  1       Open    0       0       0       0
test                     5       Open    0       0       3       0
test1                    5       Open    1       0       0       0

Configuration,

actions: "enqueue, allocate, backfill"
tiers:
- plugins:
  - name: priority
  - name: gang
  - name: conformance

What you expected to happen: I'm expecting 1 Job will be evicted from test queue and Job in test1 queue will be running. But Job in test1 queue is in Inqueue state. How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

  • Volcano Version: v1.3.0
  • Kubernetes version (use kubectl version):
  • Cloud provider or hardware configuration:
  • OS (e.g. from /etc/os-release):
  • Kernel (e.g. uname -a):
  • Install tools:
  • Others:

Can you help fot that? @renhuanyu

@Sharathmk99 please config reclaim action and try again.

actions: "enqueue, allocate, backfill, reclaim"
tiers:
- plugins:
  - name: priority
  - name: gang
  - name: conformance

  - name: predicates

actions should include reclaim if you want to use Fair sharing feature

lowang-bh avatar Jul 15 '21 03:07 lowang-bh

@wpeng102 @lowang-bh Included reclaim in action. Still same issue,

Name                     Weight  State   Inqueue Pending Running Unknown
default                  1       Open    0       0       0       0

test1                    5       Open    1       0       0       0

Config,

Restarted all 3 pods, kubectl rollout restart deployment -n volcano-system

Do I need to share any other details?

@lowang-bh @wpeng102 Is my Job manifest correct?

@wpeng102 @Thor-wl @renhuanyu could you please help me to figure out the issue?

Sharathmk99 avatar Jul 16 '21 04:07 Sharathmk99

reclaim works when multiple conditions met the requirement: you can check it from AddReclaimableFn

  1. gang plugin: preemptable := job.MinAvailable == 0 || job.MinAvailable <= job.ReadyTaskNum()-1
  2. conformance-plugin: evictor can not reclaim pod in system namespace or with system-priority
  3. drf plugin:
  4. proportion : victimee's queue derserve large than its allocated(that means it is overused)

@Sharathmk99 could you change the scheduler log level to V=4 and append the scheduler log again? you can edit the scheduler deployment and modify -v=4 in container args

@Sharathmk99 Thank you for append the scheduler log, please confirm if set PriorityClass for the volcano job. From the code logic if the preemptor priority is higher than preemptees's, the gang plugin will reject for job preemption.

https://github.com/volcano-sh/volcano/blob/44ec8eb28df26fbacd03ab15edabfc5916900c25/pkg/scheduler/plugins/gang/gang.go#L90-L94

@wpeng102 priorityClass is same for all volcano jobs.

But test queue is using resources more than deserved, a job from test queue should get evicted right?

Sharathmk99 avatar Jul 23 '21 07:07 Sharathmk99

@Sharathmk99 Thanks for reporting this issue, https://github.com/volcano-sh/volcano/issues/1642 should share the same root cause with this one.

For the workaround, maybe you can try exchage gang and proportion postion

actions: "enqueue, allocate, backfill, reclaim"
tiers:
- plugins:
  - name: priority
  - name: proportion
  - name: conformance
- plugins:
  - name: gang

  - name: predicates

@wpeng102 After exchanging gang and proportion position, still no luck,

@wpeng102 I did restart the deployment after configmap changes k rollout restart deployment -n volcano-system volcano-scheduler

Sharathmk99 avatar Jul 26 '21 10:07 Sharathmk99

@wpeng102 I tried to build docker image from master branch. But still the issues is same. Not able to reclaim guarantee resource for second queue. Is it possible to solve the above use case with Volcano?

@Thor-wl @wpeng102 Can you help me to make fair sharing work? Is my Kubernetes version 1.21 a problem?

I0726 09:19:31.510263 1 gang.go:100] Victims from Gang plugins are []

hi @Sharathmk99 , for volcano v1.3.0, the most important log pasted l found was:

I0726 09:19:31.510246       1 proportion.go:236] Victims from proportion plugins are []

related logic is:

for _, reclaimee := range reclaimees {
  ...
  allocated.Sub(reclaimee.Resreq)
  if attr.deserved.LessEqualStrict(allocated) {
    victims = append(victims, reclaimee)
  }
}
klog.V(4).Infof("Victims from proportion plugins are %+v", victims)

for your queue test, l found this log:

Queue <test>: deserved <cpu 10000.00, memory 0.00, hugepages-2Mi 0.00>, allocated <cpu 11000.00, memory 0.00>, share <1.1>

so the situation may be that allocated first subtracts a value, which leads to deserved > allocated, and eventually causes skippe the calculation of vicitim. It was a bug in v1.3.0, related fixes is https://github.com/volcano-sh/volcano/pull/1540

@shinytang6 Thank you for the response. I did tried to build docker image from master branch and test it, but still it doesn't work.

Ideally test queue should deserved 5000 and test1 should deserved 5000 and default queue should deserved 1000. Do i need to share any other log?

Below is the log from master branch docker images,
