A message transmission method and apparatus in a cluster file system includes determining, by a first host in a cluster file system, that the message network link is faulty; switching from the message network link for message transmission to a storage channel; generating a first message; and recording the first message in a first location area of a data storage medium, where the first location area is used by a second host to access and read the first message.

Message transmission method and apparatus in cluster file system

The present disclosure discloses a read/write path determining method and apparatus. The method is used by a physical host. The method includes: obtaining, by the host, a first read/write request of the virtual machine, where the first read/write request includes a first virtual address, searching for the first virtual address in an address translation information set, and determining to process the first read/write request by using the block device or the virtual block device according to the address translation information set and the first virtual address. According to the method and apparatus, an appropriate read/write path is determined according to a read/write request and an address translation information set, so that both storage performance and a storage function can be considered.
