[0002] In the existing virtualization environment, take volume migration (or template deployment) as an example, if the user file system in a virtual machine contains three files, namely file1, file2 and file3, and the three files are stored in In the user virtual disk in the virtual machine, and these three files are also stored in the data volume in the storage virtualization layer in the hypervisor (management program), but when file3 in the user virtual disk in the virtual machine is deleted , the file3 in the storage virtualization layer is not deleted synchronously, and since the storage virtualization layer does not perceive the user file system, when migrating (or importing and exporting) the data volume in the storage virtualization layer, the user The deleted file3 in the virtual disk will still be copied, that is, useless data will be copied, resulting in a waste of space and affecting system performance

The embodiment of the invention discloses a processing method and apparatus for virtual data storage. The method comprises the following steps of acquiring a disk partition list and identifying user file systems corresponding to a target disk partition in the disk partition list, identifying user data storage positions in the user file system to determine an effective storage position, looking for user effective data from a source data volume from a storage virtual layer and generating a target data volume containing user effective data. According to the processing method and apparatus, useless data can be prevented from being copied in the virtual environment, so system performance can be improved.
Description
technical field [0001] The present invention relates to the technical field of computer virtualization, in particular to a storage virtualization data processing method and device.
