Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention
Embodiment be described in detail.It should be noted that in the absence of conflict, in the embodiment and embodiment in the application
Feature can mutual any combination.
Step shown in the flowchart of the accompanying drawings can be in a computer system such as a set of computer executable instructions
It executes.Also, although logical order is shown in flow charts, and it in some cases, can be to be different from herein suitable
Sequence executes shown or described step.
The embodiment of the present invention proposes a kind of distributed type lock management method and device based on storage, by being arranged such as
The maximum node number that sanlock distributed lock is supported dynamically to adjust the space size of the single resource occupation of distributed lock,
Optimize memory space resource to use, while the I/O size of sanlock can be reduced, speeds sanlock lock reactor speed.
One embodiment of the invention provides a kind of distributed type lock management method, completes distributed lock using this method and configures
The process used is as shown in Figure 1, include：
Step 101, the value for updating maximum node number option.
The embodiment of the present invention is illustrated for using sanlock to implement distributed lock.
In this step, by configuration file mode, the maximum node number of sanlock support can be dynamically set.
Step 102, according to preset maximum node number option, dynamically calculate single distributed lock input and output I/O
The size of block.
In this step, optimization sanlock locks resource offset, directly becomes input number from the multiple of the 1M inputted originally
Word, while number is converted to the resource size in memory and multiplied in number by inside, carries out the unit particle size of storage resource into one
Step refinement.
Maximum node number is read from configuration file, based on offset, configures memory, according to following formula,
Calculate the size of single distributed lock I/O block：
Lock space size/(512* (the maximum node number+2)) of the size of distributed lock I/O block=total.
Step 103 distributes distributed lock I/O block for each node.
In this step, as soon as distributing a distributed lock I/O block for each node, subsequent each node is obtained using distribution
Distributed lock I/O block.
Preferably, the distributed lock I/O number of blocks that occupancy can not be limited when distributed lock is used in a manner of small documents.
For example, adjustment sanlock I/O mode, to issue I/O according to the maximum node number of configuration.Again it compiles
The rpm packet of sanlock, normal deployment use sanlock.
By modifying sanlock I/O mode, the reading write-in of originally fixed length becomes to adjust by reading sanlock memory
The block size of whole reading only reads the content of block size, mitigates I/O pressure.
Step 104, each node read and write corresponding distributed lock I/O block, complete locking or unlock.
One embodiment of the invention additionally provides a kind of distributed lock management device, and structure is as shown in Fig. 2, include：
Dynamic memory space configuration module 201, it is single for dynamically calculating according to preset maximum node number option
The size of distributed lock input and output I/O block；
Space distribution module 202, for distributing distributed lock I/O block for each node.
Preferably, the dynamic memory space configuration module 201 is specifically used for calculating single point according to following formula
The size of cloth lock I/O block：
Lock space size/(512* (the maximum node number+2)) of the size of distributed lock I/O block=total.
Preferably, which includes：
Parameter configuration module 203, for updating the value of the maximum node number option.
The embodiment provides a kind of distributed type lock management method and devices, according to preset maximum node number
Option dynamically calculates the size of single distributed lock input and output I/O block, distributes distributed lock I/O block for each node.It is real
The flexible configuration for having showed distributed lock resource uses, and solves the problems, such as that the wasting of resources and read or write speed are slower.
It is realized by the code of optimization sanlock distributed lock, increases dynamically configurable maximum node number option,
That modifies offset simultaneously enters ginseng, and the carry out calculations of offset of internal dynamic optimizes the rate of distributed lock, while increasing same
The number for the distribution distributed lock I/O block resource that one block space is supported.The block of I/O when reducing distributed lock each resource acquisition
Size improves I/O rate, improves the speed for obtaining resource.
