I have an elasticsearch cluster which has the storage field set to 10Gi, i want to resize this cluster (for testing purposes to 15Gi). However after changing the storage value from 10Gi to 15Gi i can see that the cluster still did not resize.
From what i can tell the aws-ebs storage https://kubernetes.io/docs/concepts/storage/storage-classes/ allows for volume expansion wehn the field allowVolumeExpansion is true. But even when i have this, the volume is never expanded when i change that storage value
