Technical field
The present invention relates to computer memory technical field, especially relate to a kind of disk method for supervising and the system of optimizing acceleration.
Background technology
In a storage management system, disk is as the most basic storage medium, and be the important medium preserving data, the stability of quality on storage system of disk has great impact, therefore in a storage management system, is very important to the monitoring of disk.
Under normal circumstances, in a storage system, except monitoring the status information of disk itself, also can there is certain interactive relation with other modules, as storage pool correlation module in disk management module.One or more disk is created a storage pool, then using the operand of this storage pool as data access, and reading and writing data is not carried out to monolithic disk itself.Therefore, we are when carrying out monitoring management to disk, except whether whether the state relating to disk itself have bad block, have except abnormality alarming information, usually also can have certain mutual with other modules.
Except the information that the status information sum interactive module of disk itself is relevant, we also pay special attention to disk positional information on the physical devices, can orient relevant disk quickly and accurately when going wrong.But based on the pluggable property of disk, the positional information of disk usually changes, when as occurred low-quality disk, we can perform and change dish operation, when front disk can be removed, have new disk to add system.And for example when current memory capacity cannot meet the up-to-date demand of client, we can expand the hardware device stored, and add disk or add disk frame (jbod).These operations all can be changed the physical topological structure of storage system, need the relevant information again obtaining disk.
Implementation is in the past that back-end system initiatively monitors the status information refreshing disk, performs the status information of scanning hardware, inquiry disk in real time.This kind of implementation can recognize the change of the topological structure of storage and the status information of disk undoubtedly in real time.But we find by actual test, such implementation Data Update is comparatively slow, and the order execution time is longer, and it is larger that front end page refreshes time delay.
Another implementation optimized is in database by the deposit data of acquisition, the inquiry of back-end system is separated with the display of front end page, data in back-end system independence refresh, front end page then from database Query Information show, it is slow that this kind of implementation effectively solves Refresh Data, the problem that page furbishing time delay is larger, but need to perform a large amount of system commands because each database data refreshes, partial order time of return is longer, time delay causes more greatly Refresh Data not in time, the data variation that peripheral operation causes cannot be presented in front end page in the very first time.
And above-mentioned two schemes all Problems existing be continual inquiry disc information, have a large amount of I/O operation to disk, certain interference can be produced to the access of business datum.In addition, when occurring disk failures, partial order performs time-out also can cause adverse influence to the operation of whole system.

The present embodiment provides a kind of disk method for supervising optimizing acceleration, realized by disk management module, information relevant for all disks needing to obtain is deposited in a database, whether have to change according to inquired about information and determine whether again the field of Query Information more in new database, and then obtain Disk State according to the database after upgrading.The method comprises the following steps: the type 1) obtaining disk relevant information to be checked, judges whether the disk relevant information of the type changes, and if so, then performs step 2), if not, then perform step 3); 2) perform the operation of corresponding database update according to the type of disk relevant information to be checked, as shown in Figure 1, then perform step 3); 3) the disk relevant information in Query Database, obtains disk current state.
One, the disk management information definition that need obtain and depositing
The information that disk management need obtain is as shown in table 1, and the Database field depositing disk relevant information is consistent with the information that will obtain.
Table 1
Two, data base updating procedure
Following three kinds of situations are mainly divided into process to the renewal of database:
1) for the change of the real-time information relevant with I/O operation and the real-time information relevant with system cloud gray model duration, then real-time inquiry and database update is carried out;
2) information caused for the operation of interactive module changes, then notify that disk management module carries out Refresh Data by interactive module;
3) cannot detect for system, the artificial hardware variation triggered, upgrades back-end data base as plug disk then adopts client manual triggers to refresh.
To achieve these goals, the present invention mainly comprises following main points:
1, will the disk relevant information obtained be needed to classify.
A) real-time query information: along with a large amount of I/O operation of system or can run for a long time, the spontaneous information changed, be the information that real-time information and query manipulation are lower to system interference, comprise disk size, disk manufacturer, disc product numbering, disc version information, disk I/O mistake, disk temperature and disk smart health status;
B) interactive module relevant information: comprise state in storage pool of storage pool belonging to disk, disk and whether place storage pool is exported;
C) hardware change affects information: the information of the change that the peripheral operation that system cannot detect causes, as plugged dish, the increase of the disk that change hardware topology etc. causes and minimizing, the change of disk slot, the change etc. of disk frame information, comprise the disk frame of ownership belonging to disk, disk frame path, disk frame numbering and disk slot number.
2, the determination of the communication plan of disk management module and interactive module.
Communicating of interactive module (storage pool correlation module) and disk management module realizes by kinds of schemes, as by global variable, carrying out the transmission of information by revising the value of variable, determining whether the data of interactive module change by the setting of global variable and change.Specific as follows:
1) default value arranging global variable is that 0 expression need not obtain the information relevant with interactive module again, and nonzero value represents that data relevant with disk in interactive module change, and needs refresh data again.
2) interactive module is to the operation of global variable, if each storage pool causes the information of disk management module to change after having operated, revises global variable, makes its value be not equal to default value.
3) disk management module is to the operation of global variable, and inquiry global variable, judges whether to need again to inquire about storage pool relevant information; Reset global variable, the data identifying current acquisition are again from the data of system queries.
3, database deposits the refresh step of information
1) when program starts, perform all relevant system commands and obtain the relevant information of all disks, empty the information of legacy data storehouse record, by the information that newly obtains stored in database.
2) according to the type of disk relevant information to be checked, judge whether the disk relevant information of the type changes, and carry out associated databases renewal rewards theory.
A) refresh process of real-time query information
If disk relevant information to be checked belongs to real-time query information, then be directly judged to change, by real-time executive system order inquiry real-time query information, more new database.
B) refresh process of interactive module relevant information
As shown in Figure 3, if disk relevant information to be checked belongs to interactive module relevant information, then inquire about global variable, be judged to change when the value of global variable is not equal to default value, inquiry real-time query information and interactive module relevant information, again obtain global variable, judge current global variable and the last global variable inquired about whether consistent, if, then more new database, and reset global variable, if not, then rejudge disk relevant information and whether change.
In whole refresh process, after having obtained real-time information, the global variable of front and back inquiry is compared, whether have operation to cause Data Update during being intended to judge data query, whether also need executive system order again to inquire about up-to-date disc information.
If during inquiring global variable inconsistent representative inquiry real-time information after having obtained real-time information for twice, storage pool module has operation to cause the data when obtaining not to be up-to-date data, when therefore next time refreshes, need again inquire about storage pool relevant information.So global variable can not be reset.
C) hardware change affects the refresh process of information
If disk relevant information to be checked belongs to hardware change affect information, be then judged to when there being hardware to change to change, by the renewal of client manual triggers database.As shown in Figure 2, when there being hardware to change, the refresh operation of manual triggers will perform all relevant system commands to process during manual refreshing operation, has certain time delay.After query manipulation completes, more all data in new database, the information before avoiding showing refresh operation during next client query.
If when disk relevant information d) to be checked at least comprises two types, then need the data clearly with which operation refreshed to be as the criterion, the priority of the present embodiment database update operation is: hardware change affects information > interactive module relevant information > real-time query information.Because manual refreshing queried all information of disk, comprising storage pool relevant information, meanwhile, the time interval of refreshing in real time is shorter, and Data Update is very fast, therefore when a conflict exists based on the data of manual refreshing.
