Problems solved by technology

[0007] However, when the LV is being used, that is, when the cloud hard disk corresponding to the LV is mounted to the virtual machine and is powered on, the LV is still being used at this time, and the mapping table cannot be removed at this time, which will eventually lead to the release of resources. (i.e. LV) fails, the watchdog heartbeat times out

Abstract

The invention discloses a locked resource configuration method based on shared storage. The method comprises the steps that a logical volume locking service process calls a Device Mapper mapping tablemanagement tool to prohibit follow-up IO request operations between a volume group and real target equipment, and after IO request operations sent to logical volumes are completed, the real target equipment mapped by the logical volume corresponding to a failure generated by a multi-path data distribution link in a mapping table of the Device Mapper is replaced with pseudo target equipment. According to the method, the phenomenon that all computing nodes are reset and shut down due to the fact that a sanlock triggers a watchdog when the heartbeat of the watchdog is out of time can be avoided,therefore, other virtual machines mounted on the computing nodes are avoided, the phenomenon that the virtual machines mounted with ceph cloud hard disks are forced to suspend responding is avoided,and then the high availability and stability of a cloud platform are improved.

Description

technical field [0001] The invention relates to the technical field of cloud storage virtualization, in particular to a shared storage-based locking resource configuration method in a virtualized storage system in cloud computing. Background technique [0002] As the mainstream storage method in the virtualized storage system in cloud computing, shared storage is mainly used to provide data support for virtual machines (VMs) and upper-layer services, and to manage shared storage by relying on the file system. However, due to the limitation of the performance of the file system itself, the performance of the shared storage provided by the file system is far inferior to that of the block storage. Therefore, the current mainstream open source cloud computing platforms usually use the block storage to manage the shared storage. [0003] In block storage, LVM (Logical Volume Manager, Logical Volume Manager) is usually used, and LVM provides a management mechanism for disks or par...
