Description
Technical field
The invention belongs to server test technical field, and in particular to a kind of Rack racks JBOD in a production environment is stored
Method of testing.
Background technology
JBOD（Just a bunch of disks, JBOD, or sometimes referred to as simple driving binding）Be one not
Too regular term, official's term is referred to as " Spanning ", and it is used to refer to also not according to RAID（RAID）
Computer hard disc of the system configuration to increase serious forgiveness and improve data access performance.
RAID system redundantly stores same data on multiple disks, and this multiple disk is in operating system
Just as a disk.Although JBOD also allows multiple disks to appear only one of which, it is by the way that multiple drivers are merged
Accomplish this point into a big logic magnetic disc.JBOD does not bring any benefit using independent disk, can not
The benefits such as the fault-tolerant or better performance that any RAID can be brought are provided.
Multiple disks are all included in use because JBOD is general, therefore total memory capacity is very huge, and if one
The failure of individual disk will result in the failure in whole equipment, certainly will be a great risk to system.It is one of to solve
Method is software RAID.From the point of view of host side, do not appointed logically with hardware RAID using software RAID and JBOD combination
What is distinguished, and simply software RAID can consume a part of host resource, and compared with hardware RAID, it is impossible to reach high performance system
Rigors.
Based on the low serious forgiveness of JBOD storages itself, particularly important is become to the reliability testing of product in itself.
The content of the invention
It is an object of the present invention to for above-mentioned existing issue, there is provided a kind of Rack racks in a production environment of design
The method of testing of JBOD storages, to solve above-mentioned technical problem.
In order to achieve the above object, the technical scheme is that：
A kind of method of testing of the racks of Rack in a production environment JBOD storages, it is characterised in that specific steps include：
（1）The filling system built for server on server is controlled in JBOD；
（2）Basic function inspection is carried out, basic function has been checked and no problem carries out step (3)；
（3）Steady testing is restarted in progress, is restarted completion and is checked that no problem carries out step (4)；
（4）Pressure test is carried out to JBOD storage devices, pressure test no problem carries out step (5)；
（5）Basic function is checked, is checked out of question, is terminated test.
Further, basic function checking step includes：
（21）Check the quantity of JBOD storage hard disks；
（22）Check hard disk smart information；
（23）Check hard disk whether there is to report an error；
（24）Inspection system daily record.
Further, step（3）In restart mode including cold restart and hot restart.
Cold restart：JBOD storage devices are powered off, basic function inspection of being started shooting after upper electricity can be according to actual feelings
Condition carries out multiplicating test.
Hot restart：Refer in the case where JBOD equipment is not powered off, carrying out operating system using linux system restarts, weight
Open progress basic function inspection after completion.
Further, step（4）Middle pressure test comprises the following steps：
（41）Installation toolkit；
（42）Write test script and I/O read-write pressure tests are carried out to hard disk.
Further, test script content includes test file title, the I/O for testing random write, tests random write and read
I/O, single IO block file size, the magnitude range of data block, this test file size, testing time, I/O engine make
The ratio accounted for and display result are write with mode, mixing read-write mode.
Further, test script content also includes setting test process to bypass the buffer register that machine is carried, and makes survey
Test result is truer.
Further, step（24）Whether the middle mode inspection system daily record with crawl keyword reports an error.
Further, using the systems of open source linux centos 7, using Shell as test language, realize and JBOD is stored
Performance test.
The beneficial effects of the present invention are the present invention is namely based on the system Shell language of open source linux centos 7, profit
With conventional testing tool, the production test stored to Rack racks JBOD is completed, unstable product or part is screened, in addition originally
All test events of the reference of invention can becoming one test script, the achievable automatic test of start, raising efficiency.
In addition, design principle of the present invention is reliable, and it is simple in construction, with application prospect widely.
As can be seen here, the present invention compared with prior art, improves with prominent substantive distinguishing features and significantly, and it is implemented
Beneficial effect be also obvious.
Brief description of the drawings
A kind of method of testing flow chart for the racks of Rack in a production environment JBOD storages that the present embodiment is provided.
Embodiment
Below in conjunction with the accompanying drawings and the present invention will be described in detail by specific embodiment, following examples are to the present invention
Explanation, and the invention is not limited in implementation below.
The method of testing for a kind of racks of Rack in a production environment JBOD storages that the present embodiment is provided, using increasing income
The systems of Linux Centos 7, using Shell as test language.Based on the lsscsi instruments carried using system, with
Smartctl is that hard disk detects instrument, using fio as hard disk pressurizing tool.Realize to a series of performance tests of JBOD.
As shown in Figure 1, specific steps include：
（1）The filling system built for server on server is controlled in JBOD, high-volume cluster uses PXE modes；
（2）Basic function inspection is carried out, basic function has been checked and no problem carries out step（3）；
（3）Steady testing is restarted in progress, is restarted completion and is checked that no problem carries out step（4）；
（4）Pressure test is carried out to JBOD storage devices, pressure test no problem carries out step（5）；
（5）Basic function is checked, is checked out of question, is terminated test.
Basic function inspection includes：
（21）JBOD storage hard disk quantity is checked with lsscsi instruments；
（22）Hard disk smart information is checked with smart-i orders；
（23）Order smart-a/dev/sdx checks hard disk whether there is and reported an error；
（24）Inspection system daily record, main purpose is exclusive PCR, and the present embodiment is crucial using crawl by taking dmesg daily records as an example
Whether the mode inspection system daily record of word reports an error.
Step（3）In restart mode including cold restart and hot restart.
Cold restart：JBOD storage devices are powered off, basic function inspection of being started shooting after upper electricity can be according to actual feelings
Condition carries out multiplicating test, and the present embodiment is restarted using 10 times.
Hot restart：Refer in the case where JBOD equipment is not powered off, carrying out OS using linux system restarts, and restarts completion
Basic function inspection is carried out later, and the present embodiment is restarted using 10 times.
