  • ESXi
  • シンプロビジョニング Lazy/Eager zeroed

問題

  • 仮想マシンをパワーオンすると、以下のエラーで失敗します:

Reason: Thin/TBZ disks cannot be opened in multiwriter mode..
Cannot open the disk '/vmfs/volumes/xxxxxxxx-xxxxx-xxxxxxxxxxxxxxx/Windows Server 2008/VM.vmdk' or one of the snapshot disks it depends on.
VMware ESX cannot open the virtual disk, "/vmfs/volumes/xxxxxxxx-xxxxx-xxxx-xxxxxxxxxxx/Windows Server 2008/VM.vmdk" for clustering. Please verify that the virtual disk was created using the 'thick' option

  • ディスク拡張とともに、Lazy zeroed から Eager zeroed への変換が開始されました
  • スナップショットは、変換が完了する前に、ディスク拡張後に作成されました
  • 変換に時間がかかるため、スナップショットが作成され、クローンが取り出されてマッピングされましたが、VMの電源をオンにすることができませんでした
