Detailed Description
The core of the application is to provide a storage pool planning method, device, equipment and computer readable storage medium, so as to effectively improve the efficiency and reliability of storage pool planning and reduce the storage cost and labor cost.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all 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 application.
The embodiment of the application discloses a storage pool planning method, which mainly comprises the following steps of:
s1: a target storage node is determined.
Specifically, the storage pool planning method provided by the present application may be specifically applied to a distributed system, and unlike a manual configuration manner in the prior art, the method provided by the present application may be deployed in the distributed system in a software program manner, thereby implementing efficient automatic configuration.
When the method provided by the application is used for planning the storage pool of the distributed system, firstly, a target storage node, namely a storage node where a target hard disk to be added into the target storage pool is located, can be determined. It will be readily appreciated that in a distributed system, each node is provided with its own node identity. In order to further meet the customized requirements of different users in different application scenarios, the target storage node may be determined according to the related information input by the user. Of course, a person skilled in the art may also automatically select some storage nodes as target storage nodes according to a preset selection algorithm, which is not limited in the present application.
S2: and determining the set rule which is met by the hard disk in the target storage pool.
As described above, since different types and attributes of data files have different requirements on storage performance, in order to fully utilize the advantages of the storage hard disks and improve the storage utilization, the hard disks with the same performance may be set as a storage pool for storing the corresponding types of data files. Thus, similarly, the rule characteristics of the target storage pool, i.e., which hard disk is constructed according to which set rules is satisfied, may be determined according to the relevant information input by the user.
Specifically, as a preferred embodiment, the setting rule includes any one or any combination of the following: the method comprises the following steps of hard disk interface type rules, hard disk capacity size rules, hard disk rotating speed size rules and fault domain type rules to which the hard disks belong.
Wherein the hard disk interface type rule is used for defining the interface type of the hard disk in the target storage pool. The hard disk interface is a connecting component between the hard disk and the host system and is used for transmitting data between the hard disk cache and the host memory. Different hard disk interfaces determine the connection speed between the hard disk and the computer, and in the whole system, the quality of the hard disk interfaces directly influences the program running speed and the system performance. Generally, the common hard disk interfaces can be divided into IDE, SATA, SCSI, fibre channel and SAS. For example, for a target storage pool for storing internet data files, because the internet data files are generated at a high speed and in a large quantity, SAS hard disks with higher performance may be generally used.
The hard disk capacity size rule is used to define the capacity size of the hard disk in the target storage pool. Specifically, since placing hard disks of different sizes into one storage pool may cause imbalance of storage performance, in order to improve such a situation, the hard disks of the same size may be placed into one target storage pool, for example, only a hard disk of 4T in size may be placed into the target storage pool.
The hard disk rotating speed size rule is used for limiting the rotating speed size of the hard disk in the target storage pool. Similarly, the rotation speed is also an important performance index of the hard disk, so in order to further improve the balance of the storage performance of the target storage pool, only the hard disks with the same rotation speed standard can be put into the target storage pool.
The fault domain type rule of the hard disk is used for limiting the fault domain type of the hard disk in the target storage pool. A failure domain refers to a group of servers, storage and/or network connection components, etc. in a cluster that are within the scope of the failure. For the storage system, the hard disks in different failure domains are relatively independent from each other, and when one hard disk or the storage node where the hard disk is located fails, the normal storage use of the hard disks in other failure domains is not influenced.
Those skilled in the art can select one of the above setting rules or select multiple setting rules at the same time, and the present application is not limited thereto.
S3: and searching for the hard disk which accords with the set rule in the target storage node.
After setting rules of the target storage node and the hard disk in the target storage pool are determined, scanning and searching can be performed in the target storage node according to the setting rules, so that the hard disk meeting the setting rules in the target storage node is determined.
It is easy to understand that the target storage node is not only likely to be one storage node, and therefore, when there are a plurality of target storage nodes, scanning needs to be performed in each target storage node to find out all the hard disks in the target storage nodes that meet the set rule.
S4: the hard disk is added to the target storage pool.
And when the condition that all the hard disks in the target storage pool are allowed to be added in the target storage node according with the set rule is determined, the construction operation of the storage pool can be executed, and the hard disks are all added in the target storage pool so as to finish the planning of the target storage pool.
It should be further noted that, due to application needs, users often need to construct multiple storage pools, and therefore, the storage pool planning method provided by the present application may be repeatedly executed so as to complete the planning and construction task for each storage pool.
The storage pool planning method comprises the steps of determining a target storage node; determining a set rule which is met by a hard disk in a target storage pool; searching a hard disk which accords with a set rule in a target storage node; the hard disk is added to the target storage pool. Therefore, the storage pool planning method provided by the application can accurately determine all hard disks to be added into the target storage pool by searching through determining the setting rule of the hard disks in the target storage pool and the distribution range of the nodes where the hard disks are located, thereby completing the planning and construction of the target storage pool. The method can be deployed in a distributed system to automatically operate, effectively improves the processing efficiency and reliability of storage pool planning, and reduces the storage cost and the labor cost.
On the basis of the above contents, as a preferred embodiment, after searching for a hard disk in the target storage node that meets the set rule, the storage pool planning method further includes: and if the search fails, generating error-reporting prompt information.
Specifically, after the target storage node is determined and the setting rule of the hard disk in the target storage pool is determined, if any hard disk meeting the setting rule is not found in the target storage nodes, the target storage pool is failed to be constructed this time. Preferably, an error notification message may be generated to prompt the user in time, so that the user may modify and adjust the target storage node and/or the setting rule to perform the planning on the target storage pool again.
The storage pool planning apparatus provided by the present application is described below.
Referring to fig. 2, fig. 2 is a block diagram illustrating a storage pool planning apparatus according to the present application; the method comprises the following steps:
the determining module 1 is used for determining a target storage node and determining a set rule which is met by a hard disk in a target storage pool;
the searching module 2 is used for searching a hard disk which accords with a set rule in a target storage node;
and the execution module 3 is used for adding the hard disk into the target storage pool.
Therefore, the storage pool planning device provided by the application can accurately determine all hard disks to be added into the target storage pool by searching through determining the setting rule of the hard disks in the target storage pool and the distribution range of the nodes where the hard disks are located, thereby completing the planning and construction of the target storage pool. The device can be deployed in a distributed system to automatically operate, so that the processing efficiency and reliability of storage pool planning are effectively improved, and the storage cost and the labor cost are reduced.
