-------------------------------------
Summary: Do not make reservations for pods that have Pending
Volumes
Key: YUNIKORN-2421
URL: https://issues.apache.org/jira/browse/YUNIKORN-2421
Project: Apache YuniKorn
Issue Type: Bug
Reporter: Niels Geuze
I am using Persistent Volume Claims which use a storageclass that has a
topology constraint (allowedTopologies) to it. Today I had several times that
for some reason the Persistent Volume Claim remained in the Pending state but
Yunikorn still decided to make a reservation for the pod on a node. This
prevented any other pods from being scheduled on said node util the PVC was
Bound and the pod could start or until the pod was deleted.
I think Yunikorn should check whether all mounted PVCs are Bound and only then
try to make a reservation to prevent locking nodes that could do other tasks.
