Referring to fig. 1, fig. 1 is a flowchart illustrating an SDS resource cleaning method in a super-fusion virtualization system according to an embodiment of the present invention. The method comprises the following steps:
s110: the SDS resource chain of the super-fusion virtualization system is divided into a storage providing unit and a storage using unit in advance.
The storage providing unit comprises an SDS, a target created under the SDS and LUN resources created under the target, and the storage using unit comprises a physical disk for mapping the LUN resources to the server, a storage pool created under the physical disk, a virtual disk created under the storage pool and a virtual machine using the virtual disk.
It should be noted that, referring to fig. 2, the core of the super-fusion is storage virtualization and computation virtualization, that is, storage resources or services are provided for a virtual machine to use, so as to implement a computation function. The SDS is constructed by a series of servers with resources such as local disks, ten-gigabit network cards and the like, each server is used as an SDS node of the SDS, and a plurality of SDS nodes form the SDS.
Specifically, in the embodiment of the present invention, a manner of an IP-SAN is taken as an example to describe in detail, as shown in fig. 3, when an SDS is built, firstly, the SDS creates a target used by the IP-SAN, and creates LUN resources under the target, wherein a plurality of LUNs can be created under one target, a host in the SDS is connected to the target through a network, and the target and the LUNs are manners in which the SDS provides a storage service to the outside. The host in the SDS is connected with the target through the network, LUN resources are converted into physical disks of the physical server, then storage pool resources are created on the physical disks, the storage pools are used for creating virtual machines and storing the virtual disks, and one virtual machine can have a plurality of virtual disks. In the embodiment of the present invention, after the SDS is built, the SDS resource chain may be divided, the target and the LUN are divided into storage providing units, and the physical disk, the storage pool, the virtual disk and the virtual machine are divided into storage using units.
S120: the method comprises the steps of removing the constraint relation among first resources to be cleaned in a storage using unit in an SDS resource chain to be cleaned, and cleaning the first resources to be cleaned at one time;
it should be noted that, when the SDS needs to be cleaned, for an SDS resource chain to be cleaned of the SDS to be cleaned, first cleaning each first resource to be cleaned in a storage usage unit in the SDS resource chain to be cleaned, and then cleaning each second resource to be cleaned in a storage providing unit, wherein, because there are logical constraints and coupling relationships between resources in the SDS resource chain, each first resource to be cleaned in the storage usage unit in the SDS resource chain to be cleaned is determined first, because there is a constraint relationship between the first resources to be cleaned, the constraint relationship among the first resources to be cleaned is removed first, because there is no constraint between the first resources to be cleaned, the first resources to be cleaned can be cleaned at one time, that is, there is no need to clean each first resource to be cleaned layer by layer, the first resources to be cleaned are cleaned at one time, and the cleaning efficiency is high.
S130: and removing the constraint relation among the second resources to be cleaned in the storage providing unit in the SDS resource chain to be cleaned, and cleaning the second resources to be cleaned at one time.
Specifically, after each first resource to be cleaned in the storage using unit is cleaned, each second resource to be cleaned in the storage providing unit is cleaned, wherein after each second resource to be cleaned is found out, because a constraint relation exists between each second resource to be cleaned, the constraint relation between each second resource to be cleaned needs to be removed first in order to clean each second resource to be cleaned at one time, and after the constraint relation is removed, the second resources to be cleaned are cleaned at one time, so that the cleaning of the SDS is completed. Even if the SDS is in fault, the resources to be cleaned in the SDS can still be cleaned, which is beneficial to reserving the original virtualization environment and rebuilding the SDS.

Furthermore, after the above-mentioned one-time cleaning of each first resource to be cleaned, the method further includes:
and cleaning the first bottom layer information corresponding to each first resource to be cleaned.
It should be noted that after the platform resources are cleaned, the bottom layer also needs to clean the corresponding bottom layer information. Specifically, the method comprises the following steps:
generating corresponding first cleaning marks according to the first resources to be cleaned;
and determining the first bottom layer information to be cleaned from the bottom layer of the corresponding server according to the first cleaning marks, and cleaning the first bottom layer information.
That is, in practical application, after the platform resource of the storage use unit is cleaned, each first cleaning mark may be generated according to each first resource to be cleaned, that is, one first resource to be cleaned generates one first cleaning mark, where the first cleaning mark may include an identification code uniquely corresponding to the first resource to be cleaned, and then first bottom layer information corresponding to the first resource to be cleaned is determined from a bottom layer of a corresponding server according to each first cleaning mark, where the first bottom layer information includes a corresponding bottom layer configuration file, service information, a record file, and the like, and then the first bottom layer information is cleaned, and of course, a physical disk in the corresponding server needs to be deleted, thereby completing cleaning.
Further, the process of removing the constraint relationship between the second resources to be cleaned in the storage providing unit in the SDS resource chain to be cleaned in S130 and cleaning each second resource to be cleaned at one time includes:
acquiring a second logic dependency relationship of each resource in a storage providing unit in the SDS resource chain to be cleaned, and determining each second resource to be cleaned according to the second logic dependency relationship; each second resource to be cleaned is LUN resource, target and SDS;
the external key constraint between the second resources to be cleaned is set to be null;
and simultaneously executing cleaning operation on each second resource to be cleaned, and cleaning each second resource to be cleaned at one time.
It should be noted that, according to the second logical dependency relationship of each resource in the storage providing unit in the SDS resource chain to be cleaned, each second resource to be cleaned, LUN resource, target, and SDS may be further determined, then the foreign key constraints between each second resource to be cleaned are obtained, and then the foreign key constraints are cleared, so that the foreign key constraints between each second resource to be cleaned are removed, and then the cleaning operation is simultaneously performed on each second resource to be cleaned, so as to implement secondary cleaning.
Optionally, after each second resource to be cleaned is cleaned once, the method further includes:
and cleaning second bottom layer information corresponding to each second resource to be cleaned.
It should be noted that after the platform resources are cleaned, the bottom layer also needs to clean the corresponding bottom layer information. Specifically, the method comprises the following steps:
generating each second cleaning mark according to each second resource to be cleaned;
and determining second bottom layer information to be cleaned from the corresponding SDS node bottom layer according to the second cleaning marks, and cleaning the second bottom layer information.
That is, in practical application, after the platform resources of the storage providing unit are cleaned, each second cleaning mark may be generated according to each second resource to be cleaned, that is, one second resource to be cleaned generates one second cleaning mark, where the second cleaning mark may include an identification code uniquely corresponding to the second resource to be cleaned, and then second bottom layer information corresponding to the first resource to be cleaned is determined from the bottom layer of the corresponding SDS node according to each second cleaning mark, where the second bottom layer information includes corresponding bottom layer configuration files, service information, record files, and the like, and then these second bottom layer information are cleaned, and of course, the physical disk in the corresponding server needs to be deleted, thereby completing cleaning. Further, after performing one-time cleaning on each second resource to be cleaned, the method further includes:
a out-of-service notification is sent to each SDS node within the SDS such that each SDS node stops providing services based on the out-of-service notification.
Specifically, after the SDS is cleared, a service stop notification may be sent to each SDS node in the SDS, and after each SDS node receives the service stop log, each SDS node stops providing the service according to the service stop notification.
Therefore, the SDS resource chain is divided into two units, the SDS, the target and the LUN resource form a storage providing unit, the physical disk, the storage pool, the virtual disk and the virtual mechanism form a storage using unit, when the SDS resource chain to be cleaned needs to be cleaned, the storage using unit and the storage providing unit of the SDS resource chain to be cleaned can be cleaned respectively at one time, the cleaning efficiency is improved, and the constraint relation among the resources to be cleaned is removed during cleaning, so that the cleaning of the SDS resource chain to be cleaned can be realized when the SDS fails, and the original virtual environment is reserved and the SDS is built again.
