const EtcdMainVolumeClaimTemplateName = "main-etcd"

EtcdMainVolumeClaimTemplateName is the name of the volume claim template in the etcd-main StatefulSet. It uses a different naming scheme because Gardener was using HDD-based volumes for etcd in the past and did migrate to fast SSD volumes recently. Due to the migration of the data of the old volume to the new one the PVC name is now different.
