Accordingly, X86controller can select to control agent or the arm controller of instance system, uses Data in update1 subregion recover android system, or by the data upgrading android system in update2 subregion. When recovery or the upgrading that X86controller selects the agent controlling instance system to carry out android system, agent can be Arranging a file in data or cache subregion, record enters task to be performed after recovering (recovery) pattern, e.g. Utilize update1 subregion data recover android system, still utilize update2 subregion data upgrading Android system System;It is to perform by the program of recovery1 subregion or perform by the program of recovery2 subregion after restarting.Above-mentioned file is complete Cheng Hou, agent can restart Android system.
Uboot subregion is the boot partition of the android system in instance system, when android system starts, at first Perform the program in uboot subregion.Program in uboot subregion passes through logical operations, can arrange according to arm The agent of controller or instance system carries out the priority of android system upgrading or recovery.For example, it is possible to by root Carry out android system upgrading according to arm controller or recovery is set to have precedence over and carries out upgrading or recovering according to agent.
Based on examples described above system and cloud system, if the android system in instance system is being run Meet with power-off or other fortuitous events during recovery pattern, cause the partition datas such as system, kernel imperfect, Android system cannot be properly functioning, can arrange the suitable signal of telecommunication by arm controller and trigger, be again introduced into Recovery pattern is until success, it is also possible to the assignment file arranged at corresponding subregion by agent is advanced into again certainly Recovery pattern, re-executes the system upgrade or recovery tasks being not fully complete.Said process, can be by reality as shown in Figure 2 The upgrading of example system or restoration methods (i.e. the upgrading of operating system or restoration methods in instance system) describe, and the method includes Following steps:
S201: start android system;
Program in S202:uboot subregion according to the signal of telecommunication of arm controller or agent in corresponding subregion The file arranged, it is judged that android system is the need of entering recovery pattern;
If need not enter recovery pattern, then operating system is properly functioning, otherwise
S203: enter recovery pattern, the signal of telecommunication or agent according to arm controller are in corresponding subregion The file arranged, determines the task of needing to perform;
S204: from corresponding recovery subregion (including recovery1 and recovery2) and/or update subregion (bag Include update1 and update2) read data, complete task;
S205: restart android system.
If additionally, the recovery of android system or upgrading task are the literary compositions arranged in corresponding subregion according to agent Part, then delete corresponding file after completing task, it is to avoid again calls these files during subnormal startup under android system.
Those skilled in the art, on the basis of concrete technical scheme described above, can construct its other party completely Case.Such as, the operating system in instance system, other operating systems can be taked, dividing on the memorizer of respective instance system District may change.In the upgrading of instance system or restoration methods, if some operating system completes recovery or upgrading task Need not restart, then delete step S205.Numerous to list herein.
