問題

PVのONTAPボリュームがPVCサイズよりも大きく、クローンが存在する場合、PVCのリサイズが以下のメッセージとともに失敗します：
requested PVC size '10995116277760' is too large for the clone source '10871334256640'
しかし、Tridentのtrident-controllerログには、実際のエラーが以下のとおりだったことが示されています：
unable to resize the volume: unsupported capacity range; effective volume size 21990232555520 including any snapshot reserve is less than the existing volume size 22183062540288
