Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing is combined, to this
Invention is described in detail.Following disclosure provides many different embodiments or example is used to realize different knots of the invention
Structure.In order to simplify disclosure of the invention, hereinafter the component of specific examples and setting are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relationship between various embodiments and/or setting is discussed.It should be noted that illustrated component is not necessarily to scale in the accompanying drawings
It draws.Present invention omits the descriptions to known assemblies and treatment technology and process to avoid the present invention is unnecessarily limiting.
The pressure for being provided for the embodiments of the invention NAS virtual machine system under a kind of MCS system with reference to the accompanying drawing is surveyed
Method for testing is described in detail with system.
As shown in Figure 1, the embodiment of the invention discloses a kind of method for testing pressure of NAS virtual machine system under MCS system,
The following steps are included:
S1, the NAS virtual machine for logging in each node under duplication script to/tmp/ catalogue, and assign script and weigh accordingly
Limit；
S2, CPU obtain MCS resource, and past/dev/null equipment persistent loop carries out 0 write-in；
S3, toward persistently carrying out 0 write-in under src equipment；
If S4, virtual machine is restarted during applied voltage test, correlation log is recorded.
The embodiment of the present invention recycles script by shell and carries out CPU and memory progress pressure test to NAS virtual machine, and
Record the abnormal restarting information in pressure test sequence.
It logs in the NAS virtual machine of each node, under duplication yali.sh script to/tmp/ catalogue, and assigns yali.sh foot
This corresponding permission executes yali.sh script in each NAS void machine node later, after operation for 24 hours, checks/root/
Empty machine abnormal restarting information whether is recorded inside bootlog.log.
The yali.sh script concrete operations are as follows:
CPU obtain MCS resource, and using dd order it is past/dev/null equipment persistent loop carry out 0 write-in, be continuously increased
Process number is until the same with physical id number:
for i in`seq 1$(cat/proc/cpuinfo|grep"physical id"|wc-l)`；Do dd if=/
Dev/zero of=/dev/nul l&done
Using dd order toward persistently carrying out 0 write-in under src equipment, and make its Infinite Cyclic:
If virtual machine is restarted during applied voltage test, records correlation log and be redirected to/root/
Bootlog.log file:
cat<<"EOF">/root/bootlog.sh
#！/bin/bash
echo"Boot at$(date)">>/root/bootlog.log
EOF
chmod+x/root/bootlog.sh
echo"/root/bootlog.sh">>/etc/rc.d/rc.local
By abnormal restarting information preservation to/root/bootlog.log file, tester is facilitated to check.In delay 10s
Afterwards, it checks whether virtual machine starts, if do not started, continues to postpone 10s；If virtual machine has been started up, continue to hold
Row pressure test script.
The embodiment of the present invention is carried out automation pressure test in script, is obtained using CPU by writing shell script
MCS resource, past/dev/nul l equipment persistent loop carry out 0 write-in, toward src equipment under persistently carry out 0 write-in, and record correlation
Abnormal restarting log not only may be implemented the pressure test to NAS virtual machine system, while can automatically record in press process
The abnormal and output abnormality of NAS void machine solves the pressure test in the prior art for NAS virtual machine system to correlation log
The problem of middle fault location low efficiency, fault location efficiency in test process is greatly improved, the realization of this method surveys automation
Examination NAS void machine stability is possibly realized.
As shown in Fig. 2, the embodiment of the invention also discloses a kind of pressure test systems of NAS virtual machine system under MCS system
System, the system comprises:
Script initial module under duplication script to/tmp/ catalogue, and is assigned for logging in the NAS virtual machine of each node
The corresponding permission of script；
CPU pressure test module obtains MCS resource for CPU, and past/dev/nul l equipment persistent loop carries out 0 write-in,
It is continuously increased process number；The increase process number is until the same with physical id number；
Memory pressure test module, for toward persistently carrying out 0 write-in under src equipment；It is persistently carried out under the equipment toward src
The operation of 0 write-in is Infinite Cyclic operation；
Logger module, if for during applied voltage test virtual machine restart, record correlation log.
The system also includes:
Exception information checks module, after being used for Run Script for 24 hours, checks inside log whether record empty machine abnormal restarting letter
Breath.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
