VSS_E_DYNAMIC_DISK_ERROR

VSS_E_DYNAMIC_DISK_ERROR VSS encountered an error while processing dynamic disks involved in the operation. Dynamic-disk configuration, disk availability, or storage-provider support needs separate verification.

What to check

Inventory all disks and volumes involved and confirm that the dynamic-disk configuration is healthy and visible to the operating system.
Check whether the backup or cluster configuration supports the selected dynamic-volume topology.
Review storage and VSS provider events for the first disk-specific error; this HRESULT alone does not identify the failed disk.
