The disclosure provides a method for virtual volume snapshot creation by a storage array. The method generally includes receiving a request to generate a snapshot of a virtual volume associated with a virtual machine, in response to receiving the request, preparing a file system of the storage array to generate the snapshot, wherein preparing the file system comprises creating a delta storage structure to receive write input/output (I/O) requests directed for the virtual volume when generating the snapshot of the virtual volume, deactivating the virtual volume, activating the delta storage structure, generating the snapshot of the virtual volume, and during the generation of the snapshot of the virtual volume: receiving a write I/O directed for the virtual volume and committing the write I/O in the delta storage structure.
