memtest in system rescue

1. offizieller Beitrag

    Hi


    i got an hardware update to my nas (Acer H 341 to H342 with a D510 instead of D410 intel processor and 4GB Ram instead of 2GB).


    I just put my old system HD into the new system and it booted well to H342..


    But now the issues started:


    1. I wanted to copy my internal data drives via MC to my external USB Backup drives for backup. But after some hours the systems hangs or reboots sometimes. Not always. .


    2. so i thought about issues with the network, which i could resolve already.


    3. Now ithink, it could be the ram.


    4. I entered "system resuce" from grub, but i am unable to find xmem86 in the x window.


    any help how to run memtest86 would be highly appreciated.


    regards

    memtest86 is in the boot menu of systemrescue.

    I guess it doesn't have it anymore. I will see about adding a memtest iso option that you can boot from (if it works).

    Actually Debian made this pretty easy. Just install the memtest86 or memtest86+ package. I think I will make memtest86+ a dependency of the kernel plugin so it gets installed automatically when the plugin does. Both packages add an entry to grub.

    Thanks for the workaround tip.


    I installed the memtest86+ package. First time I tried booting to it I got no output in my ipmi console. Looking into it I saw that ttyS0 was specified for the serial console in the grub entry. I changed that to the required for my use case ttyS1 and tried again. This time I got output but when the memtest started it got 34% into test #1 and hung. I could not escape out of it. I tried a few more times but it failed the same way.

    But how can i start it?


    When i do ./Memtest86.bin

    I get permission denied.

    You have to boot into memtest. You can't run it with a full OS running.

    I've never seen memtest hang and I have been using it for 15+ years. Are you sure memtest is hanging and not your console? You could install memtest86 and see if it doesn't have the issue.

    Not sure what is hanging. But the console works perfectly until I try this.


    I tried installing memtest86 but it didn't configure grub for a serial console. So I tried patching that in by hand but it didn't work; no output on the console.

    What about memtest86 over ipmi?

    That's what I have been trying. The machine is headless.

    I thought you tried memtest86+ over ipmi and serial console and memtest86 over serial console? I was suggesting memtest86 over ipmi. I have used memtest86 over ipmi many times.

    I tried both memtest86 and memtest86+ over ipmi. I don't use the physical serial port on the machine, it's serial over LAN (SOL) configured in BIOS to use ttyS1 (COMM2).


    As I said, the ipmi console works fine until I try to boot memtest86+ over ipmi where it hangs at exactly 34% into the first test every time.


    What does your memtest86 over ipmi grub.cfg entry look like?

    What does your memtest86 over ipmi grub.cfg entry look like?

    Whatever is on the older systemrescue ISOs. And it is on a Supermicro X10SL7-F. But I have also used it many times on my AsrockRack board and many, many HP DL380 G8 or Gen9 ILO adapters.

    Here's what installing memtest86 drops into grub.cfg:


    Code
    ### BEGIN /etc/grub.d/20_memtest86 ###
menuentry "Memory test (memtest86)" {
        linux16 /boot/memtest86.bin
}
### END /etc/grub.d/20_memtest86 ###


    I have tried modifying it to make it look like what is there for memtest86+ by appending the console stuff, but I get no output.

    Code
    ### BEGIN /etc/grub.d/20_memtest86 ###
menuentry "Memory test (memtest86)" {
        linux16 /boot/memtest86.bin console=ttyS1,115200n8
}
### END /etc/grub.d/20_memtest86 ###

    That would assume the image supports that argument. Not much you can do if it doesn't.

    Obviously it doesn't support it.


    My RAM is OK so I'm not worried.

    Hi,


    just wanted to let you know, how i got it installed and what´s the result (which is bad i guess...)


    First in grub i selected system recovery of the current kernel.


    when the recovery had started up i installed the memtest86+ via


    Code
    sudo apt-get update
sudo apt-get -y install memtest86+


    That worked well. Now i can select memtest in grub.


    But now the bad result:


    this is the outcome after 3hrs running memtest86+.



    i guess, i have a memory issue. Trying at the moment, to verify if it is a memory or a mainboard issue by exchange of the defective ram to a different ram, which i know worked in my old mainboard.


    fingers crossed.

    If you install memtest86+ in OMV instead of in the running systemrescue, you will get the grub entry in OMV's grub menu.
