s1 identifying the type of the storage device in the system, and judging whether the drive letter of each type of storage device is in a preset form, wherein the system has a plurality of types of storage devices, such as SATA disks and NVME disks, wherein the drive letter of the SATA disks is defaulted to sd form, OSD can be created and deployed normally through icfs-deploy, a default CRUSH MAP is constructed, the drive letter of the NVME disks, i.e., icfs-deploy, created OSD is not identified, and the CRUSH MAP cannot be automatically created, so the type of the storage device in the system needs to be identified, different types are integrated, and different types are created respectively according to whether the drive letter can be identified;
s2 building a first storage pool using a storage device whose drive letter is a preset form, in response to the drive letter of the storage device being a preset form, the preset form of the drive letter being sd form, if the drive letter of the storage device is sd form, the storage device being a SATA disk, creating and deploying a finalized OSD through icfs-deployment, building a default CRUSH MAP to form the first storage pool;
s3, responding to the disc character of the storage device not being in the preset form, creating a new disc character by using the storage device of which the disc character is not in the preset form and constructing a second storage pool based on the new disc character, wherein if the disc character of the storage device is not in the sd form, the storage device is an NVME disc, the new disc character is constructed after the disc character is set in the system, and then the second storage pool is created;
s4, the first storage pool is connected to the first application in a butt joint mode, the second storage pool is connected to the second application different from the first application in a butt joint mode, the SATA disk is general in performance, the storage pool can be constructed to be used for connecting a gland storage cloud platform mirror image, due to the fact that the NVME disk is better in performance and more excellent in running of the virtual machine, the storage pool constructed by the NVME disk can be used for processing system activities by the cloud host back end, and therefore storage resources can be utilized to the maximum degree.
By adopting the technical scheme of the invention, the reasonable utilization of storage resources can be realized to the maximum extent, and the competitiveness of products is improved.
In a preferred embodiment of the present invention, in response to the drive letter of the storage device not being in the preset form, creating a new drive letter using the storage device whose drive letter is not in the preset form and building the second storage pool based on the new drive letter comprises:
formatting storage devices of which each drive letter is not in a preset form;
in response to the completion of the formatting, creating a required mounting point and mounting the formatted storage device on the created mounting point;
creating a new drive letter of the OSD, adding a key file to the new drive letter, giving a right, setting a mounting point as the permission of operation, and then restarting an OSD node;
creating a rule of CRUSH MAP, and setting a root node in the rule as an OSD node of a storage device with a drive letter not in a preset form;
and building a second storage pool after creating the required host type and dividing the host type under the root node. The method comprises the steps of using commands such as paired or fdisk to format NVME disks one by one, formatting all storage spaces of the NVME disks into a usable state for being squeezed down for use, then creating a required icfs mount point directory, mounting the disks formatted by the user before to the created mount point after creation is completed, and then creating a new drive character of OSD. A key file is added to this new OSD script and the right is assigned. And resetting the OSD node for service after setting the whole mount point as the permission of the icfs to allow operation. A rule for creating a CRUSH MAP is provided, wherein a root node is set to be used as an OSD node of the NVME disk, and the concept of the root node is similar to a combination. A host type is set, and this is used to place the OSD of each server on a back end (i.e., bucket), for example, i have three disks on server a, and after i make the three disks into 3 OSDs, they all belong to server a. And then dividing the created host type under the created root node, and placing the OSD of which server the created OSD is under the corresponding created host. The created CRUSH RULE RULE is embodied by some configuration parameters of CRUSH MAP, which is originally default that only the default OSD node pool is searched, a RULE is newly added to the default OSD node pool to define a name, and when the pool is created, if the RULE is selected, the RULE can lead the OSD node of the manually created NVME to be found to create the needed pool.
In a preferred embodiment of the present invention, the first storage pool is a storage pool constructed by SATA disks, and the second storage pool is a storage pool constructed by NVME disks. The SATA disk has general performance, a storage pool can be constructed to be used for butting to create and storing cloud platform images, because the NVME disk has better performance and is more excellent for the operation of a virtual machine, the storage pool constructed by the NVME disk can be used for processing system activities at the back end of a cloud host, and therefore storage resources can be utilized to the maximum extent.
