No Scheduler and no Storage Capacity Tracking

[dp-42]

Hi,

we use TopoLVM for some pretty specific workloads that we "pin" directly on a node anyway - therefore we are wondering if we can disable the scheduling component completely?

I think it would work this way:

<snip>
controller:
  storageCapacityTracking:
    enabled: false
<snip>
scheduler:
  enabled: false
<snip>
webhook:
  podMutatingWebhook:
    enabled: false
  pvcMutatingWebhook:
    enabled: false
<snip>

Is this a "supported" way of have TopoLVM running?

I am a bit unsure regarding the pvcMutatingWebhook - as in the docs this is never disabled and seem to be required in both "scheduling modes"? What does it actually do?

Many thanks!

Hi dp-42.

It may work, but it does not support such a use case. Please verify the use case thoroughly and use it at your own risk.

Surely pvcMutatingWebhook should also be disabled. The docs will be corrected. Thank you.

The pvcMutatingWebhook is not related to Storage Capacity Tracking. Therefore, you do not have to disable it, but if you do, it will not work unnecessarily. The docs may not be corrected.
