The invention discloses a partition identification method of a network block device, comprising: when the client detects that the rbd-nbd process starts, the kernel of the client sends a network block device creation instruction to the network block device driver; when the network block device is created , the rbd‑nbd process establishes a connection between the network block device and the mirror device in the preset storage cluster to perform network block device protocol docking; when the network block device protocol docking is completed, a partition identification thread is created in the rbd‑nbd process; The partition identification instruction is triggered by the partition identification thread, and the scanning operation is performed according to the partition identification instruction, and the partition information of the network block device is obtained and output. The invention also discloses a partition identification device, device and storage medium of the network block device. The present invention effectively avoids the time limit of partition identification, making the partition identification time more flexible.
Description
technical field [0001] The invention relates to the field of network block devices, in particular to a partition identification method, device, device and storage medium of network block devices. Background technique [0002] A network block device (nbd device for short) is a block device widely used in Linux systems. [0003] According to the current network block device protocol, I / O requests (abbreviation for input / output (input / output)) can only be performed after the network block device and the mirror device in the storage cluster are connected through the network block device protocol. The premise of network block device protocol docking is that the network block device is ready, and the partition information of the network block device will be read before the network block device is ready. If this time is missed, manual intervention is required to read the partition of the network device, that is, the partition identification of the current network block device will...
