[PLUGIN] Live Memory Tester for UNRAID

Live Memory Tester for UNRAID

A diagnostic plugin that lets you test your RAM without needing to reboot.

 

Identify memory problems in situations where a restart is not (immediately) possible or just stress test your RAM.
This plugin provides a convenient GUI for in‐place memory testing using the veteran command-line utility memtester.

 

Installable via Community Applications

Cool ui addition idea, i can see this being useful when people have system instability issues.

did a run on 5 gb and seems to work as expected 👍

Hi,

 

tested this. Works good. Tooks about 4 Minutes for 1 GB. It´s using only 1 Core of the CPU with a 100%.

It would be interesting to see how this plugin behaves on a system that is known to have RAM issues.

Thanks for reporting back, it using only one core is normal as the memtester program is not multi-threaded. 🙂

Hello @Rysz I start testing 4 days ago for 12GB. I have 2x32GB on my system. How log that should test? Can I make plugin upgrade while it's testing?



Regards.

You didn't set a number of loops so it will run endlessly, did 100 full runs so far with no issues... i.e. you're good, just stop it.

Thanks, so 1 loop is enough?

Usually people let memory tests run for around a day or two at most, with 100 loops you'll be good.

I am curious how it works.

To test all of the memory doesnt it have to be made available to test?

How can it do this while unraid is running?

It can't test all of the memory, but it can test a large subset of your memory (e.g. 12GB out of available 16GB).

It's very useful for situations where you have no physical access or just want to do a quick preliminary test over a suspicion.

 

As an example, today we suspected RAM problems for a Discord user with OS instabilities and filesystem corruption.

Using this plugin, we quickly identified that their RAM had severe problems, becoming apparent within seconds of testing:

 

So it's not a full replacement for an extensive offline memory-test (e.g. using memtest86), but it can be helpful in situations. 🙂

Understood, about what i thought but was curious. Thanks for sharing!

If you want to test “all” you should probably just choose memtest on boot screen. I’m not sure that really tests all since at least a small portion is probably used for memtest but it should come close.

Nice utility! I just tested a system of mine which has exhibited corrupt cache drives over the course of the last year and i've just been limping it along. Failures right at the start of testing! Thanks for making this plugin so easy to use.
