This strategy handles VM-level (instance) snapshots for VMs whose volumes + * reside on ONTAP managed primary storage using the NFS protocol. It uses the + * QEMU guest agent to freeze/thaw the VM file systems for consistency, and + * delegates per-volume snapshot creation to the existing CloudStack snapshot + * framework which routes to {@code StorageSystemSnapshotStrategy} → + * {@code OntapPrimaryDatastoreDriver.takeSnapshot()} (ONTAP file clone).

+ * + *

Flow:

+ *
    + *
  1. Freeze the VM via QEMU guest agent ({@code fsfreeze})
    2. + *
  2. For each attached volume, create a storage-level snapshot (ONTAP file clone)
    3. + *
  3. Thaw the VM
    4. + *
  4. Record VM snapshot ↔ volume snapshot mappings in {@code vm_snapshot_details}
    5. + *
+ * + *

Strategy Selection:

+ *

Returns {@code StrategyPriority.HIGHEST} when:

+ *
    + *
  • Hypervisor is KVM
    • + *
  • Snapshot type is Disk-only (no memory)
    • + *
  • All VM volumes are on ONTAP managed NFS primary storage

/** - * VM Snapshot strategy for NetApp ONTAP managed storage. + * VM Snapshot strategy for NetApp ONTAP managed storage using FlexVolume-level snapshots. * *

    This strategy handles VM-level (instance) snapshots for VMs whose volumes - * reside on ONTAP managed primary storage using the NFS protocol. It uses the - * QEMU guest agent to freeze/thaw the VM file systems for consistency, and - * delegates per-volume snapshot creation to the existing CloudStack snapshot - * framework which routes to {@code StorageSystemSnapshotStrategy} → - * {@code OntapPrimaryDatastoreDriver.takeSnapshot()} (ONTAP file clone).

    + * reside on ONTAP managed primary storage. Instead of creating per-file clones + * (the old approach), it takes ONTAP FlexVolume-level snapshots via the + * ONTAP REST API ({@code POST /api/storage/volumes/{uuid}/snapshots}).

    + * + *

    Key Advantage:

    + *

    When multiple CloudStack disks (ROOT + DATA) reside on the same ONTAP + * FlexVolume, a single FlexVolume snapshot atomically captures all of them. + * This is both faster and more storage-efficient than per-file clones.

    * *

    Flow:

    *
      - *
    1. Freeze the VM via QEMU guest agent ({@code fsfreeze})
      2. - *
    2. For each attached volume, create a storage-level snapshot (ONTAP file clone)
      3. + *
    3. Group all VM volumes by their parent FlexVolume UUID
      4. + *
    4. Freeze the VM via QEMU guest agent ({@code fsfreeze}) — if quiesce requested
      5. + *
    5. For each unique FlexVolume, create one ONTAP snapshot
      6. *
    6. Thaw the VM
      7. - *
    7. Record VM snapshot ↔ volume snapshot mappings in {@code vm_snapshot_details}
      8. + *
    8. Record FlexVolume → snapshot UUID mappings in {@code vm_snapshot_details}
      9. *
    * + *

    Metadata in vm_snapshot_details:

    + *

    Each FlexVolume snapshot is stored as a detail row with: + *

      + *
    • name = {@value Constants#ONTAP_FLEXVOL_SNAPSHOT}
      • + *
    • value = {@code "::::::::::"}
      • + *
    + * One row is persisted per CloudStack volume (not per FlexVolume) so that the + * revert operation can restore individual files/LUNs using the ONTAP Snapshot + * File Restore API ({@code POST /api/storage/volumes/{vol}/snapshots/{snap}/files/{path}/restore}).

    + * *
