As shown in fig. 1, the method may include the steps of:
s1, in response to receiving the instruction to create the cloud host, determines whether a host of the cloud host to be created has been selected.
When the cloud host is created, the host can be selected by a user, the storage pool of the host can be selected through a strategy, and the host and the storage pool can also be selected through the strategy.
S2, in response to the host of the cloud host to be created having been selected, obtaining a storage pool list of all connection states on all hosts in the cloud management platform based on the IP of the selected host and obtaining an alarm threshold for the storage pool.
Aiming at the situation that a storage pool is selected by a host autonomously, when a cloud host is created on an interface end, a creation mode, namely a mode of creating the cloud host by ISO or OVA, needs to be selected, then the host is selected, because the host is selected autonomously, the host IP is known, finally, indexes such as a network card, the number of disks, a system OS and the like are selected autonomously according to needs, and then a request is sent. When the back-end service is processed, the condition of the front-end request is analyzed to intelligently judge which mode the front-end request belongs to so as to facilitate scheduling of different strategies. When a situation is identified where a host is selected autonomously, but the storage pool is selected intelligently, the selected host is the one whose connection status is available, but needs to be verified as being under the corresponding switch. Because the intelligent selection of the storage pool is designed in the scene, the storage pool capacity required by the cloud host needs to be calculated in advance, the number of all disks in the request needs to be inquired, the capacity of all the disks needs to be summed, and at the moment, the Size of the disk is known to be Size. According to service requirements, the storage pool type of an ISO creation mode can be a RAW storage pool and an OCFS storage pool, and the OVA creation mode can only be the OCFS storage pool, so that the type of the storage pool can be intelligently selected by transmitting parameter identification according to the creation mode.

in response to receiving an instruction for creating a cloud host, judging whether a host of the cloud host to be created is selected;
in response to that a host of a cloud host to be created is selected, obtaining a storage pool list of all connection states on all hosts in a cloud management platform based on the IP of the selected host and obtaining an alarm threshold of the storage pool;
screening storage pools of preset types from the storage pool list and deleting the storage pools lower than the alarm threshold;
the storage pool list is traversed and the first available storage pool is selected as the storage pool of the cloud host to be created.
2. The method of claim 1, further comprising:
in response to that the host of the cloud host to be created is not selected, acquiring and sequencing a host list of all connection states in the cloud management platform;
deleting hosts in the host list which are not in the corresponding switch;
traversing the host list, and judging whether a first preset type storage pool exists in the hosts in the host list;
and in response to the fact that the storage pool of the first preset type exists in the hosts in the host list, selecting the host of the first storage pool of the first preset type in the host list as the host of the cloud host to be created.
3. The method of claim 2, further comprising:
in response to the fact that the host in the host list does not have the storage pool of the first preset type, traversing the host list, and judging whether the host in the host list has the storage pool of the second preset type;
and in response to the fact that the storage pool of the second preset type exists in the hosts in the host list, selecting the host of the first storage pool of the second preset type in the host list as the host of the cloud host to be created.
4. The method of claim 3, wherein the first predetermined type of storage pool is an OCFS type storage pool, and wherein the second predetermined type of storage pool is a RAW storage pool.
5. The method of claim 2, wherein in response to a host of the cloud host to be created not being selected, obtaining and sorting a list of hosts of all connection states in the cloud management platform comprises:
and sorting the hosts in the host list according to the memory availability from high to low.
6. The method of claim 1, wherein the pre-configured types of pools include an OCFS type pool and a RAW pool.
7. The method of claim 6, wherein screening the list of storage pools for storage pools of a preset type and deleting storage pools below the alarm threshold comprises:
screening an OCFS non-double-active storage pool in a mounted state from the storage pool list;
screening out RAW non-double-active storage pools in a mounting state;
and sorting according to the priority of the OCFS storage pool type greater than the RAW storage pool type, and deleting the storage pools lower than the alarm threshold.
8. An apparatus for a cloud management platform to create a cloud host, the apparatus comprising:
the judging module is configured to respond to the received instruction for creating the cloud host and judge whether the host of the cloud host to be created is selected;
the system comprises an acquisition module, a storage management module and a management module, wherein the acquisition module is configured to respond to the fact that a host of a cloud host to be created is selected, acquire storage pool lists of all connection states on all hosts in a cloud management platform based on the IP of the selected host and acquire an alarm threshold of the storage pool;
the sorting module is configured to screen preset types of storage pools from the storage pool list and delete the storage pools lower than the alarm threshold;
a selection module configured to traverse the storage pool list and select a first available storage pool as a storage pool of the cloud host to be created.
9. A computer device, comprising:
at least one processor; and
a memory storing computer instructions executable on the processor, the instructions when executed by the processor implementing the steps of the method of any one of claims 1 to 7.
10. A computer-readable storage medium, in which a computer program is stored which, when being executed by a processor, carries out the steps of the method according to any one of claims 1 to 7.
