the first acquisition module is used for acquiring a target CFS storage domain of which the CFD storage is not mounted in the two continuous inquiry results obtained according to the time strategy;
the first control module is used for controlling and triggering the process of automatically mounting the CFD storage equipment which is not mounted in the target CFS storage domain;
the mount operation of the same target CFS storage domain is obtained by the following methods, including:
acquiring a host list corresponding to the target CFS storage domain;
comparing host lists in the same target CFS storage domain to obtain whether CFS storage which is not mounted due to host offline exists in the target CFS storage domain or not, and obtaining a query result, wherein the query result records the corresponding relation between the host and the CFS storage which is not mounted;
and executing comparison operation at preset time intervals, judging whether a new host appears in the query results of two times, if not, polling each host, and controlling each host to execute a mounting command according to the corresponding relation between the host and the un-mounted CFS.
7. The apparatus of claim 6, wherein:
the first control module is specifically configured to, when there are at least two target CFS storage domains, control the at least two target CFS storage domains to concurrently execute a process of mounting an unmounted CFD storage device in the target CFS storage domain; and/or controlling the host of the target CFS storage domain to execute the flow of the uninstalled CFS storage according to a preset sequence.
8. The apparatus of claim 6, further comprising:
the recording module is used for recording the times of the target CFS storage domain which continuously executes automatic mounting after controlling and triggering the process of automatically mounting the CFD storage equipment which is not mounted in the target CFS storage domain;
the second obtaining module is used for obtaining an execution result of executing automatic mounting of the host corresponding to the target CFS storage domain;
the judging module is used for judging whether the number of times of continuously executing automatic mounting in the target CFS storage domain reaches a preset number threshold value or not if the execution result is that the CFS storage is not successfully mounted, so as to obtain a judgment result;
and the second control module is used for controlling the host corresponding to the target CFS storage domain to stop automatic mounting operation if the frequency threshold is reached.
9. The apparatus of any of claims 6 to 8, further comprising:
the detection module is used for detecting whether a new host is on line in the target CFS storage domain to obtain a detection result;
and the first control module controls the host corresponding to the target CFS storage domain to execute automatic mounting operation when the detection result shows that no new host is on line in the target CFS storage domain.
10. The apparatus of claim 6, wherein the first control module comprises:
the recording unit is used for recording the times that the target CFS storage domain continuously executes automatic mounting;
the determining unit is used for determining the waiting time corresponding to the number of times of continuously executing the automatic mounting according to the preset waiting time;
and the starting unit is used for starting the next new automatic mounting process of the target CFS after the waiting time length passes after the mounting of the target CFS storage domain is finished.
