For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
According to the technical scheme, when the log writing rate is higher, the log storage resources are scheduled based on the exhaustion time of the log storage resources, so that log storage resources are prevented from being exhausted in high-frequency log writing, the problem that a cloud host is down or logs which cannot be written are lost due to the fact that the log storage resources are exhausted is solved, and the log writing capacity of the cloud host is improved.
According to an embodiment of the present invention, there is provided an embodiment of a scheduling method of storage resources, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different from that herein.
In this embodiment, a method for scheduling storage resources is provided, which may be used for an electronic device that adopts a log storage system, such as a mobile phone, a tablet computer, a server, etc., fig. 1 is a flowchart of a method for scheduling storage resources according to an embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:
S11, acquiring log storage resources and log writing rate.
The log storage resource is a storage space for storing logs, specifically, a log storage system of the electronic device may include a plurality of storage pools, each storage pool includes one or more storage volumes, each log storage volume may store log information of all cloud hosts corresponding to one node, and log information corresponding to different cloud hosts is stored under different catalogues of the log storage volume.
The log write rate is the rate at which log information is written to the log storage resource, which can be characterized using the number of bytes written to the log storage resource per second. The log writing rate can be an average value of the writing rate of the log information to the log storage resource in a certain period of time, for example, a log storage system in the electronic equipment can monitor the writing rate of the log information to the log storage resource at each moment in real time, and the log writing rate is calculated according to the average value; the log writing rate may also be a real-time rate of writing the log information monitored at the current moment into the log storage resource, and of course, the log writing rate may also be obtained by other manners, which is not limited herein specifically.
S12, calculating the exhaustion time of the log storage resource based on the log writing rate and the log storage resource.
The exhaustion time is the exhaustion time of the log storage resources, and the log storage system in the electronic equipment can determine the current log storage space according to the log storage resources and estimate the exhaustion time of the log storage resources by combining the current log writing rate. For example, the current log storage space corresponding to the log storage resource is C 0, and the log writing rate is V 0, so that the exhaustion time t=c 0/V0 can be estimated.
S13, judging whether the depletion time is smaller than the preset time.
The preset time is the shortest time for the preset log storage resource to run out, after the estimated depletion time is obtained, the depletion time is compared with the preset time to determine the relation between the depletion time and the preset time, when the depletion time is smaller than the preset time, the step S14 is executed, and otherwise, no operation is executed.
S14, carrying out resource scheduling on the log storage resources.
When the exhaustion time is smaller than the preset time, the log information is indicated to be written continuously at high frequency, at this time, the log storage system of the electronic device can schedule log storage resources, for example, expand the capacity of the log storage resources, or migrate the log storage resources to other storage pools, etc., where the resource scheduling mode is not particularly limited, so long as the scheduling mode can be implemented to expand the log storage space corresponding to the log storage resources and ensure that the log can be written normally, and those skilled in the art can determine according to actual needs.
According to the scheduling method of the storage resources, the log storage resources and the log writing rate are obtained, the consumption time of the log storage resources is calculated based on the log writing rate and the log storage resources, if the consumption time is smaller than the preset time, the log storage resources are about to be consumed, at the moment, the log storage resources are subjected to resource scheduling, the risk of log storage resource consumption is eliminated, the problem that a cloud host is down or logs which cannot be written are lost due to log storage resource consumption is avoided, and the log writing capacity of the cloud host is improved.
In this embodiment, a method for scheduling storage resources is provided, which may be used for an electronic device that adopts a log storage system, such as a mobile phone, a tablet computer, a server, etc., fig. 2 is a flowchart of a method for scheduling storage resources according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
S21, acquiring a log storage resource and a log writing rate. The detailed description refers to the corresponding related descriptions of the above embodiments, and will not be repeated here.
S22, calculating the exhaustion time of the log storage resource based on the log writing rate and the log storage resource.
Specifically, the step S22 may include:
s221, obtaining the residual space capacity corresponding to the log storage resource.
The remaining space capacity corresponding to the log storage resource is the log storage space remaining by the current log storage resource. The log storage system of the electronic equipment can count the occupied space of the existing log information in the current log storage resource, and calculate the difference between the occupied space of the existing log information and the total storage space of the log storage resource by combining the total storage space of the log storage resource, so that the residual space capacity corresponding to the log storage resource can be obtained.
S222, calculating the quotient between the residual space capacity and the log writing rate to obtain the exhaustion time of the log storage resource.
The log writing rate is the number of bytes written to the log storage resource per second, the remaining space capacity is divided by the log writing rate, the quotient between the remaining space capacity and the log writing rate can be calculated, and the quotient between the remaining space capacity and the log writing rate is determined as the exhaustion time of the log storage resource.
S23, judging whether the depletion time is smaller than the preset time. The detailed description refers to the corresponding related descriptions of the above embodiments, and will not be repeated here.
And S24, when the exhaustion time is smaller than the preset time, carrying out resource scheduling on the log storage resources.
Specifically, the step S24 may include:
s241, obtaining capacity expansion information of the log storage resource and the residual space of the storage pool corresponding to the log storage resource.
The capacity expansion information is used to represent the expansion multiple of the log storage resource, for example, the capacity expansion information may be 1.5 times of capacity expansion, may be 2 times of capacity expansion, and may be other expansion multiple of capacity, which is not limited herein specifically. The remaining space of the storage pool corresponding to the log storage resource is the current remaining storage space of the storage pool, specifically, a log storage system in the electronic device can acquire the total space of the storage pool where the log storage resource is located, count the space occupied by the log storage resource, and then determine the remaining space of the storage pool according to the total space of the storage pool and the space occupied by the log storage resource.
And S242, scheduling the log storage resources based on the capacity expansion information and the residual space of the storage pool.
The log storage system of the electronic device may determine, according to the remaining space of the storage pool, whether the log storage resource meets the capacity expansion requirement. When the residual space of the storage pool meets the capacity expansion requirement, expanding the log storage resources based on the capacity expansion information so as to realize the resource scheduling of the log storage resources; when the residual space of the storage pool does not meet the capacity expansion requirement, the log storage resources can be subjected to hot migration so as to realize resource scheduling of the log storage resources.
Specifically, as shown in fig. 3, the step S242 may include:
s1, acquiring the current residual space of the storage pool after the capacity expansion of the log storage resources.
The current residual space of the storage pool is the log storage space remained in the storage pool, the log storage system of the electronic equipment expands the capacity of the log storage resource in the storage pool where the log storage resource is located according to the capacity expansion information, and the current residual space of the storage pool after the capacity expansion of the log storage resource is calculated.
S2, judging whether the current residual space is larger than a preset space or not.
The preset space is the lowest remaining space threshold of the preset storage pool. The log storage system of the electronic device may compare the determined current remaining space of the storage pool with a preset space to determine a relationship between the current remaining space and the preset space. And when the current residual space is larger than the preset space, executing the step S3, otherwise executing the step S4.
And S3, expanding the capacity of the log storage resources based on the capacity expansion information.
If the current residual space is larger than the preset space, the residual space of the storage pool where the log storage resource is located is indicated to meet the capacity expansion requirement of the log storage resource, and at the moment, the log storage system can expand the capacity of the log storage resource according to the capacity expansion information. For example, the capacity expansion information is 1.5 times the capacity expansion, and the log storage system can expand the log storage resources in the current storage pool according to 1.5 times of the log storage resources.
S4, obtaining the storage states of the storage pools corresponding to the log storage resources and migration information of the log storage resources.
The storage status of each storage pool is used to characterize storage information of each storage pool, such as storage space remaining in each storage pool, and the estimated exhaustion time of log storage resources corresponding to each storage pool at the current log writing rate. The migration information of the log storage resource is used to thermally migrate the log storage resource to other storage pools.
If the current remaining space is smaller than the preset space, the remaining space of the storage pool where the log storage resource is located does not meet the capacity expansion requirement of the log storage resource, and at this time, the log storage resource can be thermally migrated to other storage pools to avoid the log incapable of being written when the log storage resource is exhausted.
S5, judging whether the target migration storage pool exists in each storage pool or not based on the storage state of each storage pool.
The target migration storage pool is a migration target corresponding to the log storage resource, and the log storage system of the electronic device can determine whether the target migration storage pool exists in each storage pool according to the acquired storage state of each storage pool. When the target migration storage pool exists, executing step S6, otherwise executing step S7.
For example, the target migration storage pool may be the largest remaining space, or may be the longest storage resource exhaustion time estimated by the current log writing rate, or may be determined according to other information, which is not limited herein, and may be determined by a person skilled in the art according to actual needs.
Specifically, the step S5 may include:
(1) And sequencing the storage pools based on the storage states of the storage pools to obtain sequencing results of the storage pools.
And sequencing all the storage pools according to the storage states of the storage pools to obtain sequencing results of the storage pools. Taking the remaining space of the storage pool as an example, a scheduling module is arranged in a log storage system of the electronic equipment, and the scheduling module can order the remaining space of each storage pool from large to small to obtain an ordering result of each storage pool.
(2) Based on the ranking results, it is determined whether a target migration storage pool exists in each storage pool.
And determining a target migration storage pool meeting the requirements from the storage pools according to the sequencing result of the storage pools. Taking the remaining space of the storage pool as an example, the scheduling module may find the storage pool with the largest remaining space from each storage pool according to the sequencing result of each storage pool, and use the storage pool with the largest remaining space as the target migration storage pool.
And sequencing the storage pools according to the storage states of the storage pools to obtain sequencing results corresponding to the storage pools, and determining whether target migration storage pools exist in the storage pools according to the sequencing results. According to the method, the target migration storage pool for migrating the log storage resources is determined from the storage pools, so that the utilization rate of the storage resources is improved while the log storage resources are prevented from being exhausted.
And S6, migrating the log storage resources to a target migration storage pool based on migration information.
When the target migration storage pool exists in each storage pool, the storage pool meeting the migration requirement exists, and at this time, the log storage resources can be thermally migrated to the target migration storage pool according to the migration information.
S7, obtaining new information of the storage pool and migration information of the log storage resource.
When the target migration storage pool does not exist in each storage pool, the storage pools which meet the migration requirement do not exist in all the storage pools, and at the moment, newly-built information of the storage pools can be acquired to newly-built one storage pool to migrate the log storage resources.
And S8, generating a target storage pool corresponding to the storage pool newly-built information based on the storage pool newly-built information.
The target storage pool is a storage pool for migration log storage resources, and when the target migration storage pool does not exist in each storage pool, a new storage pool can be created according to the storage pool newly created information, and the new storage pool is determined to be the target storage pool.
S9, based on migration information of the log storage resources, migrating the log storage resources to a target storage pool.
After the creation of the target storage pool is completed, the log storage resources can be thermally migrated to the target storage pool according to migration information of the log storage resources, so that the expansion of the log storage resources is realized, the target storage pool continues to store the logs written by the cloud host, and the loss of the logs or downtime of the cloud host caused by insufficient storage resources is avoided.
According to the scheduling method of the storage resources, the quotient between the residual space capacity and the writing rate is calculated by acquiring the residual space capacity corresponding to the log storage resources, and the quotient between the residual space capacity and the writing rate is used as the exhaustion time of the log storage resources. The time when the log storage resources are about to be exhausted can be determined by calculating the exhaustion time of the log storage resources, so that the log storage resources can be conveniently and timely scheduled.
The capacity expansion information of the log storage resources and the residual space of the storage pool corresponding to the log storage resources are obtained, and the log storage resources are subjected to resource scheduling based on the capacity expansion information and the residual space of the storage pool, so that the log storage resources can be subjected to resource scheduling in an actual use state, the problem that the log storage resources are exhausted during high-frequency operation is avoided, and the log writing capability during high-frequency operation is ensured.
When the current residual space of the storage pool is larger than the preset space, expanding the capacity of the log storage resources based on the capacity expansion information; and when the current residual space of the storage pool is smaller than the preset space, carrying out resource scheduling on the log storage resources based on the storage state of each storage pool and migration information of the log storage resources so as to ensure that the log of the high-frequency operation can be continuously written into the log storage resources. The risk of log storage resource exhaustion is eliminated through the capacity expansion mode and the migration mode, and reliable storage of the log is ensured while normal use of the cloud host is not affected.
The embodiment of the invention takes a specific log storage system as an example to describe the scheduling method of the storage resources, and the log storage system comprises: ceph-based distributed log storage system, log collection module, monitoring module, scheduling module and elastic telescopic module, the structure of which is shown in figure 4. The distributed log storage scheme divides log storage resources into different log storage resource pools, and each log storage resource pool is divided into different log storage volumes. Each log storage volume stores log information of all cloud hosts on one node, and different catalogues of the log storage volumes are stored according to different cloud hosts.
The log collection module is used for collecting all log information generated in the operation process of the cloud host, distinguishing the collected logs according to the nodes where the cloud host is located, storing the logs into corresponding log storage volumes, and storing the logs into different log catalogues according to the differences of the cloud host.
The monitoring module is used for monitoring the resource surplus condition of each log storage volume in each log storage resource pool in real time, recording the log writing rate in the current period of time and estimating the depletion time T of the log storage volume. Further, the monitoring module may compare the exhaustion time T with a minimum threshold time Tmin specified by the cloud platform operation and maintenance personnel, and if T < Tmin, notify the scheduling module to perform a corresponding operation.
The scheduling module receives the information about to be used up of the log storage volume transmitted by the monitoring module and then performs corresponding operations: calculating the residual capacity C of the log storage resource pool after the capacity expansion of the log storage volume, and if the residual capacity C is larger than the minimum residual capacity Cmin of the log storage resource pool, initiating a capacity expansion instruction of the log storage volume to an elastic expansion module; if the residual capacity C is smaller than the minimum residual capacity Cmin of the log storage resource pools, sequencing all the log storage resource pools according to a preset rule, selecting one log storage resource pool as a target migration storage pool, and initiating a log storage volume cross-storage resource pool hot migration instruction by an elastic expansion module; if all the log storage resource pools can not be used as the target migration storage pools of the log storage volumes, the elastic expansion module is informed of newly building a log storage resource pool in the distributed log storage system. The scheduling module transmits specific operation instructions to the elastic expansion module on the cloud host generating the log no matter what operation is performed on the log storage volume.
After receiving the instruction sent by the scheduling module, the elastic expansion module can identify the received instruction so as to perform corresponding operations of expanding the volume of the log storage volume, thermally migrating the log storage resource pool or newly creating the log storage resource pool. And for the capacity expansion instruction of the log storage volume, the elastic expansion module directly applies for storage resources in a resource pool where the storage volume is located, expands the capacity of the storage volume, feeds back stock information of the storage volume and the storage resource pool to the monitoring module after the capacity expansion is finished, and feeds back operation completion information to the scheduling module. And for a thermal migration instruction of the log storage volume, the elastic expansion module performs thermal migration operation on the log storage volume according to target log storage resource pool information in the thermal migration instruction, and can perform capacity expansion operation on the log storage volume according to the requirements of operation and maintenance personnel during thermal migration, and after the thermal migration of the log storage volume across the resource pools is completed, relevant information is fed back to the monitoring module and the scheduling module. And for the newly-built log storage resource pool, the elastic expansion module is created according to the size of the resource pool specified by the operation and maintenance personnel. And feeding back information to the monitoring module and the scheduling module after the creation is completed.
According to the log storage system provided by the embodiment, when the log storage resources are about to be exhausted, the log storage resources can be subjected to resource scheduling, the risk of exhausting the log storage resources is eliminated, the problem that a cloud host is down or logs which cannot be written in are lost due to the fact that the log storage resources are exhausted is avoided, and the log writing capacity of the cloud host is improved. By monitoring and scheduling the log storage volume, the log is written without upper limit to the greatest extent, and the log of the cloud host is ensured to be reliably stored.
