/mce/tests/page test failure

[lumanyu180]

hi,
I test mcelog , but got the error,
page-soft-then-hard.conf: triggers did not trigger as expected: 4 != 6
My mcelog version is : mcelog mcelog-144-10.94d853b2ea81.el7
I see it inject 6 error，and page-soft-then-hard.conf has memory-ce-threshold = 1 / 1h，so i think mcelog should run triggers 6 times. Why page-soft-then-hard.conf has trigger: 4 ?

@andikleen hope for your reply , Thanks very much!

Do you mean tests/page/page-soft-then-hard.conf ? The trigger comment is commended out with '#', the only thing that matters is the number in the memory-ce-threshold, which is 1 It injects more to make sure there is only one trigger in the hour.

hi ,

Sorry, i don't understand your meaning. I just want to say: the test suit failed. I don't kown why it failed. And other test suit for example cache is succefull. when run cache test suit , the result is : cache.conf: triggers trigger as expected ! . But i run page test suit, the result is :page-soft-then-hard.conf: triggers did not trigger as expected: 4 != 6. Why ?

hope for your replay.
Thanks very much !

I don't know. It could be either the kernel or mcelog. Do you use a standard kernel? What does the system log say?

hi:
I use a standard kernel with 4.9.29. This is the system log:
[root@H3C page]# cat page-soft-then-hard.log
mcelog: failed to prefill DIMM database from DMI data
Kernel does not support page offline interface

Can you tell me why page-soft-then-hard.conf write # trigger: 4 ? I think it inject 6 errors. so why trigger is 4 ? The page-soft-then-hard.log show there are 6 errors ,
hope for your replay.
Thanks very much !

@lumanyu180
From your log " cat page-soft-then-hard.log", I can only see that 3 errors injected and the script was triggered for 3 times. The number of injected errors matched the number of triggering. So I don't see the mismatch happen. Did you paste the full log?

Hi,
Thanks for your reply. I past the full log . I think there are 6 times "Running trigger ../trigger" and MCE 0 , MCE 1, MCE 2, MCE 3, MCE 4, MCE 5, also 6 times . So i think it inject 6 errors ,and triggers are also 6 times。
