# StorageClasses — Applied after Longhorn installation
# The default 'longhorn' SC is created by Helm chart
# These are additional specialized classes

# CNPG-specific StorageClass for PostgreSQL volumes
# CNPG handles filesystem ownership via securityContext.fsGroup (UID/GID 26)
# Separate from default 'longhorn' to allow CNPG-specific tuning
