環境

  • NetApp Astra Trident
  • Ubuntu
  • ONTAP SANドライバ
  • iSCSIマルチパス

問題

Tridentで作成されたボリュームにはマウントパスがあり /dev/mapper/mpathN 、ボリューム /dev/dm-N が共存
例:
# df -h | grep /dev
...
/dev/mapper/mpathd    49G   76K   47G   1% /var/lib/kubelet/pods/[ID]/volumes/kubernetes.io~csi/pvc-[ID]/mount
/dev/dm-1        30G   20G  8.7G  69% /var/lib/kubelet/pods/[ID]/volumes/kubernetes.io~csi/pvc-[ID]/mount
/dev/dm-2        20G  4.2G   15G  23% /var/lib/kubelet/pods/[ID]/volumes/kubernetes.io~csi/pvc-[ID]/mount
