Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a routing method for supporting disaster recovery in a virtualization system according to an embodiment of the present invention, where the method is applicable to a virtualization system, and in particular, to a host of the virtualization system;
referring to fig. 1, the method may include:
s100, constructing a plurality of strategy routes from a plurality of data network port groups to a target storage, determining the priority of the strategy routes according to the sequence of the construction of the strategy routes, and constructing the later strategy routes with higher priority; wherein one data network port group corresponds to one policy route to the target storage.
The embodiment of the invention can construct the strategy route to the target storage on the data network port group and support the strategy route to the same target storage on different data network port groups, so that one data network port group can correspond to one strategy route to the target storage; therefore, a data network is constructed by creating policy routes to the same storage on a plurality of data network port groups, and the host access target storage can have a plurality of optional access paths, namely, the host access target storage can be accessed by a link corresponding to any constructed policy route.
After a plurality of strategy routes to the target storage are constructed, the priority of the strategy routes is determined according to the construction sequence of the strategy routes, and the target storage is accessed only through the link corresponding to the strategy route with the highest priority at present;
optionally, in the embodiment of the present invention, the priority of the policy route may be determined according to the construction sequence of the policy route, and the later the policy route is constructed, the higher the priority is.
Policy routing may be considered as a more flexible packet routing and forwarding mechanism than routing based on a target network, and how to process a packet to be routed is determined by a routing table.
Step S110, accessing the target storage by using the link corresponding to the policy route with the highest priority in the policy routes.
After a plurality of policy routes are constructed, only the policy route with the highest priority in the plurality of policy routes plays a role at the same time, namely, the policy route with the highest priority in the plurality of policy routes is linked to the target storage, so that the access of the target storage is realized.
Step S120, if the link supported by the policy route with the highest priority is detected to be out of order, deleting the policy route with the highest priority from the plurality of policy routes, and enabling the policy route with the second priority to function by default; wherein, among the plurality of policy routes, the second priority policy route has a priority next to the policy route with the highest priority.
Step S130, after the policy route with the highest priority is deleted, the link corresponding to the policy route with the second priority is used for accessing the target storage.
Optionally, after selecting a policy route with the highest priority from the multiple constructed policy routes and accessing the target storage under the action of the policy route, the embodiment of the present invention may detect whether the policy route with the highest priority is faulty in real time or at regular time, where the method for detecting the fault of the policy route may be implemented in a manner of querying a disk, that is, the virtualization system may detect whether the policy route with the highest priority is faulty currently in a manner of querying a disk;
when the virtualization system detects that a link supported by a policy route with the highest priority among the plurality of constructed policy routes fails in a disk query manner, the embodiment of the invention can delete the policy route with the highest priority and enable the sub-priority policy route to function (the sub-priority policy route is the policy route with the highest priority among the remaining policy routes after the policy route with the highest priority is deleted, and among the plurality of constructed policy routes, the priority of the sub-priority policy route is next to the policy route with the highest priority, and the link corresponding to the sub-priority policy route is used for accessing the target storage, so that when a problem occurs in a certain data network port group of the link target storage, the link corresponding to the sub-priority policy route is used for accessing the target storage to guarantee the storage of the host, and the disaster recovery capability of the virtualization system using the storage is improved.
The routing method for supporting storage disaster recovery provided by the embodiment of the invention comprises the following steps: establishing a plurality of strategy routes from a plurality of data network port groups to a target storage, determining the priority of each strategy route according to the sequence of the strategy route establishment, and establishing a later strategy route with higher priority; wherein, one data network port group corresponds to a strategy route to the target storage; accessing the target storage by using a link corresponding to the policy route with the highest priority in the policy routes; if the link supported by the policy route with the highest priority is detected to be failed, deleting the policy route with the highest priority from the plurality of policy routes, and enabling a default sub-priority policy route to function; wherein, among the plurality of policy routes, the second priority policy route is second in priority only to the policy route with the highest priority; and then the corresponding link is routed by the secondary priority strategy to access the target storage.
It can be seen that, in the virtualization system, while the separation of the data network and the management network traffic and the construction of the host to the stored multiple links are realized, the embodiment of the present invention can construct multiple policy routes from multiple data network port groups to the target storage, determine the priority of the policy route according to the sequence of the policy route construction, and one data network port group corresponds to one policy route to the target storage, and then access the target storage through the link acted by the high-priority policy route first, and when the link acted by the high-priority policy route is disconnected due to a fault, delete the policy route immediately, take effect the sub-priority policy route, access the target storage through the link acted by the sub-priority policy route, and circulate the link acted by the sub-priority policy route, so that when the high-priority policy route stored by the link target has a problem, the corresponding link can be routed through the sub-priority policy route, and accessing the target storage, ensuring the access of the host to the storage and improving the disaster recovery capability of the virtualization system for using the storage.
Optionally, when constructing multiple policy routes from multiple data network port groups to a target storage, the embodiment of the present invention may set a corresponding routing table for each data network port group, and one data network port group corresponds to one routing table, so that in the routing table corresponding to each data network port group, the policy routes from the corresponding data network port group to the target storage are respectively constructed, and the later the construction time of the policy route is, the higher the priority is;
further, after a plurality of policy routes are constructed in the above manner, when a policy route with the highest current priority where a link fails is deleted, the policy with the highest priority and the corresponding routing table may be deleted.
For example, as shown in fig. 2, the data network port group and the target storage are in the same network segment, vlan of the management network port group, the data network port group 1 and the data network port group 2 is 0, and is in the same network segment with the target storage, and the computing node is connected to the target storage through the physical switch; when adding a policy route to a data network port group, in practical application, taking target storage as single control storage as an example, a policy route to the target storage can be respectively established for each data network port group, and the specific method comprises two steps:
1. creating routing tables
ip route flush table1 (clearing routing Table1, table1 represents routing Table 1)
ip route flush table2 (clear routing table2, table2 represents routing table 2)
ip route add 100.2.29.0/24dev Datapg1table 1 (adding a Datapg1 (data network port group 1) route in the routing table1 for routing the traffic from host to 100.2.29.0/24 through Datapg 1)
ip route add 100.2.29.0/24dev Datapg2table 2 (adding Datapg2 (data network port group 2) route to route host to 100.2.29.0/24 through Datapg2 in routing table 2.)
Refreshing cache
ip route flush cache
2. Add strategy
ip rule add to100.2.29.5table 1
ip rule add to100.2.29.5table 2
Flushing arp cache
ip neigh flush all
It can be seen that, if the data network port group and the target storage are in the same network segment, for each data network port group, the embodiment of the present invention may empty the initial routing table corresponding to the data network port group, add the route, transmitted by the host traffic through the data network port group, to the empty routing table, and add the policy of IP (protocol for interconnection between networks) from the data network port group to the target storage to the routing table.
The embodiment of the invention can be the policies that the routing table1 and the routing table2 are added to the target storage 100.2.29.5 respectively, wherein the priority of the policy added later is higher than that of the policy added before, the first policy acts on the table1, the second policy acts on the table2, and the currently effective policy is the second policy, so that when the system detects that the link from the Datagrg 2 to the target storage is disconnected, the system automatically deletes the second policy and the table2 acting on the second policy, so that the routing table acting on the first policy and the first policy acts, and the effective link from the Datagrg 1 to the storage; in practical application, at this time, a data network port group Datapg3 may be newly created, and a policy route is added to construct a data link to be stored, so that the newly created policy route becomes an effective policy route.
It should be noted that the virtualization system can be responsible for completing virtual fusion, allocation as needed and efficient management of the bottom layer physical resources, so that the agility and flexibility of resource delivery can be obviously improved, the use efficiency of the resources is improved, and uninterrupted resource guarantee and scalable resource supply are provided for the upper layer service;
a virtualization system is generally constructed based on an open source module openvswitch; the virtual switch in the virtualization system is also generally constructed through openvswitch, a management network, a data network and a computing network can be created on the virtual switch, the switch where the management network is located is called a management network switch, each virtual switch can be bound with one or more network cards to perform traffic switching, and a port group of the same vlan cannot exist on a standard switch;
in FIG. 2, IP addresses may be configured on the data network port set to communicate the host with the storage; and the routing of the IP packet is performed by taking the established strategy as the main basis.
On the other hand, as shown in fig. 3, if the data network port group and the target storage are in different network segments, the vlans of the management network port group, the data network port group 1, and the data network port group 2 are all 0, the computing Node is connected to the storage through the internet, and at this time, a policy route is added to the data network port group, taking constructing a policy route for the two data network port groups as an example, the following two operations are required:
1. creating routing tables
ip route flush table1 (clear routing table 1)
ip route flush table2 (clear routing table 2)
ip route add default via 10.25.7.1dev data pg1table 1 (create default route for data network port group in routing table1, the created default route is used for accessing across network segments)
ip route add default via 10.25.7.1dev data pg2table 2 (create default route for data network port group in routing table2, the created default route is used for accessing across network segments)
ip route add 10.25.7.0/24dev Datapg1table 1 (route is added for data network port group in routing table1, where the added route is for forwarding through Datapg1 when traffic goes to 10.25.7.0/24)
ip route add 10.25.7.0/24dev Datapg2table 2 (route is added to the data network port group in routing table2, where the added route is for forwarding through Datapg2 when traffic goes to 10.25.7.0/24)
Refreshing cache
ip route flush cache
2. Add strategy
ip rule add to 100.2.29.5table 1 (policy added to destination store 100.2.29.5 in routing Table 1)
ip rule add to 100.2.29.5table 2 (policy added to destination store 100.2.29.5 in routing Table 2)
Flushing arp cache

It can be seen that, if the data network port group and the target storage are in different network segments, for each data network port group, the initial routing table corresponding to the data network port group may be cleared, a default route of the data network port group is created in the cleared routing table, the default route is used for accessing across network segments, a route through which the traffic of the host is transmitted through the data network port group is added, and then the data network port group is added to the IP policy of the target storage for the routing table.
As described above, in a specific application, the virtual switch where each data network port is located is associated with a physical network card, and here, the main consideration is to separate the data network from the management network, at this time, since the policy acting on the table2 is added later, the priority is to act on the policy of the table1, therefore, when the host detects that the link acted by the high-priority policy is disconnected, the host immediately executes the command to delete the policy acting on the table2 and the table2, and the policy of the secondary priority immediately acts to establish a new data link, thereby improving the disaster recovery capability of the system; meanwhile, a new virtual switch and a new data network port group can be continuously added, a physical network card is associated, and policy routes respectively reaching 100.2.29.5 are continuously constructed on the data network port group, so that a link with the function of the newly added policy route becomes a current effective link.
In the embodiment of the invention, the embodiment of the invention can construct a plurality of policy routes from a plurality of data network port groups to the target storage, determining the priority of the policy route according to the adding sequence of the policy route, wherein one data network port group corresponds to one policy route to the target storage, then the link acted by the high-priority policy route accesses the target storage, and when the link acted by the high-priority policy route is disconnected due to a fault, the policy route is immediately deleted, the sub-optimal policy route is taken into effect, the links acted on by the sub-optimal policy route access the target storage, and the loop is performed, so that when the high-priority policy route of the link target storage has problems, the target storage can be accessed through the corresponding link of the strategy route of the secondary priority, the access of the host to the storage is guaranteed, and the disaster recovery capability of the virtualization system for using the storage is improved.
