Abstract

The embodiment of the present invention discloses a method, device and medium for unloading a virtual machine data disk, which receives an unloading command from a target data disk, and when the target data disk has an IO operation, according to the type of the virtual machine system corresponding to the target data disk, call The path acquisition rule matching the system type of the virtual machine is used to obtain the mount point of the target data disk on the virtual machine. Perform a freeze operation on the file system corresponding to the mount point, so that all IO operations on the target data disk are suspended. When there is no IO operation on the target data disk or after the freeze operation is performed on the file system corresponding to the mount point, the unmount operation can be performed on the target data disk. This technical solution can support virtual machines of various operating systems to safely uninstall data disks, prevent users from serious problems such as data disk uninstallation failure or user data loss due to IO operations when uninstalling data disks, and realize safe uninstallation of data disks.

Description

technical field [0001] The present invention relates to the technical field of cloud services, in particular to a virtual machine data disk unloading method, device and computer-readable storage medium. Background technique [0002] When users use the virtual machines provided by the cloud platform on a daily basis, they often mount and unmount the data disks attached to the virtual machines frequently due to work needs. , the cloud platform will continue to try to unmount the data disk. When the read and write operations last for a long time, the cloud platform will give up unmounting the data disk and prompt the user that the unmounting of the data disk failed. [0003] Since the cloud platform unloads the data disk through libvirt to perform related operations on the virtual machine, and the task of unloading the data disk is an asynchronous operation, the cloud platform has notified the user that the unloading of the data disk failed, but the unloading task on the libvi...
