Disclosed are a fault diagnosis method, device and apparatus, and a readable storage medium in the disclosure. The method includes: obtaining log files of an RAID card in a server to be monitored; determining whether the RAID card and a hard disk managed by the RAID card have a fault according to a fault diagnosis rule base and the log files of the RAID card, and providing a fault processing solution by using the fault diagnosis rule base when a fault is determined to exist, where the fault diagnosis rule base is established by analyzing historical faults of the RAID card and the hard disk managed by the RAID card in advance; and outputting a log file that determines that the RAID card and/or the hard disk managed by the RAID card has a fault, and the fault processing solution.
