Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the disclosed embodiments of the present invention.
The following further illustrates embodiments of the invention in terms of specific examples.
The system mirror image is divided into five partitions, namely a starting partition, a first system partition, a second system partition, a user partition and a backup partition. The two system partitions contain the same content and are file systems which are backed up with each other. The boot partition contains the basic boot component, which is a read-only partition. The user partition is a configuration file, an audit log, a temporary file and the like customized by the user, and the normal starting of the system is not influenced even if the partition is damaged. And the backup partition reserves system installation files for system emergency reloading.
When the system is started, the system firstly enters initramfs to prepare for switching the root file system. In initramfs, a file in a first system partition is read first, whether an error flag file exists is judged, if the error flag file does not exist, an error flag file is created, a loading partition is set as an address of the first system partition, and then necessary system modules are loaded and root partition switching is carried out. And if the error mark file exists, reading whether the error mark file exists in the second system partition, if the error mark file does not exist, writing the error mark file, setting the loading partition as the address of the second system partition, and then loading the necessary system module and switching the root partitions.
If the error mark files exist in both the system partitions, the fact that both the system partitions have problems or the previous starting is not finished is shown, in order to prevent misjudgment caused by a starting process terminal, both the system partitions are verified, and which root file system is switched is determined according to a verification result. If the two system partitions are not verified, the first system partition is automatically repaired and reinstalled by using the files in the backup partition, an alarm is notified, and field personnel judge the next operation.
And after the system partition is loaded, checking the current partition, and deleting the error sign file after the error is checked.
Furthermore, the method disclosed according to an embodiment of the present invention may also be implemented as a computer program executed by a CPU, and the computer program may be stored in a computer-readable storage medium. The computer program, when executed by the CPU, performs the above-described functions defined in the method disclosed in the embodiments of the present invention. The above-described method steps and system elements may also be implemented using a controller and a computer-readable storage medium for storing a computer program for causing the controller to implement the functions of the above-described steps or elements.
The embodiment of the invention realizes the system fault switching and recovery of the virtual NAS host through the independent double backup partitions and the backup partition; meanwhile, the last starting state is judged in initramfs by using an error sign file to select the system which really runs at this time; in addition, an error flag file is created before switching, and the error flag file is deleted after the system starts to complete self-checking to identify the integrity of the system partition.
As can be seen from the foregoing embodiments, the backup system switching method provided in the embodiments of the present invention uses an initial random access file system to access a first system partition of a system image to determine whether an error identification file exists in the first system partition by responding to a boot of the system by a boot partition of the system image; accessing a second system partition of the system image using the initial random access file system to determine whether an error identification file exists in the second system partition in response to determining that the error identification file exists in the first system partition; performing a system check on both the first system partition and the second system partition in response to determining that the error identification file exists in the second system partition; and in response to the fact that the first system partition and the second system partition do not pass system verification, acquiring a system installation file from the backup partition of the system image to reinstall the first system partition, and sending an alarm message for guiding manual intervention, so that the failure of starting the virtual machine system caused by the failure of the system disk partition can be prevented.

The method of claim 3 or 4, wherein loading essential system modules and switching a root partition using the first system partition or the second system partition comprises: setting an address of the first system partition or the second system partition in the system image as a load partition, and loading necessary system modules and switching a root partition using the load partition.
6. The method of claim 1, wherein the error identification file is configured to log boot errors and logs associated with last boot failures of the partition in which the error identification file is located.
7. The method of claim 1, further comprising performing the steps of:
in response to determining that at least one of the first system partition and the second system partition passes system checks, loading necessary system modules and switching a root partition to boot a system using the one system partition that passed system checks.
8. The method of claim 1, further comprising performing the steps of:
deleting the error identification file from the first system partition or the second system partition in response to confirming that the first system partition or the second system partition passes system verification after booting a system using the first system partition or the second system partition.
9. The method of claim 1, wherein the system image further comprises a user partition configured to store user-associated data, and wherein the user-associated data is not invoked at system startup.
10. A backup system switching apparatus, comprising:
a processor;
a controller storing program code executable by the processor, the processor executing the following steps when executing the program code:
accessing a first system partition of a system image using an initial random access file system to determine whether a misidentified file is present in the first system partition in response to booting a system boot through a boot partition of the system image;
in response to determining that the error identification file is present in the first system partition, accessing a second system partition of the system image using the initial random access file system to determine whether the error identification file is present in the second system partition;
performing a system check on both the first system partition and the second system partition in response to determining that the error identification file exists in the second system partition;
and in response to determining that neither the first system partition nor the second system partition passes system verification, obtaining a system installation file from the backup partition of the system image to reinstall the first system partition, and sending alarm information guiding manual intervention.
