Mcelog Dimm Location, The /etc/mcelog/dimm-error-trigger and /etc/mcelog/socket-memory-error-trigger scripts are executed when a DIMM or a CPU socket exceeds a configured corrected or uncorrected memory error threshold. Feb 15 12:22:38 AMPUERON-UNRAID mcelog: failed to prefill DIMM database from DMI data Feb 15 12:22:38 AMPUERON-UNRAID mcelog: Kernel does not support page offline interface DMI DIMM decoding currently only works on Intel Xeon 55xx, 56xx, E5 (Romley) systems It also requires the DMI BIOS to report the DIMMs in a specific non-standardized format, which may not be ECC: Detect 2bit, Correct 1bit (SECDED) Needs ECC memory and server grade memory controllers Scrubbing Lockstep, Chipkill Handle broken rank or DIMM with sophisticated 对于未纠正的错误，mcelog 捕获错误的能力取决于错误导致热重启还是硬重启。 如果是热重启，信息会被 mcelog 捕获，恢复后可看到。 硬重启会导致数据丢失，而且 mcelog 可能捕获不 Bank Locator: A1_NodeX_ChannelY_DimmZ with X socketid, Y channel, Z DIMM and the A1 part being ignored.

The DIMM and socket memory error triggers The /etc/mcelog/dimm-error-trigger and /etc/mcelog/socket-memory-error-trigger scripts are executed when a DIMM or a CPU socket exceeds a configured In addition to the page being offlined, if the DIMM corresponding to the failed address exceeds the factory programmed DIMM threshold, the SP generates a fault that is forwarded to the host and Use DMI information from the BIOS to prepopulate DIMM database. That's the format mcelog is looking for. 5 . Previously when it happened it was a ram issue and i have since replaced it. The mcelog daemon tracks memory errors in different buckets: per DIMM (if available) per Channel per memory controller per Socket (= physical CPU package) per Page. Note this might not work with all BIOS and requires mcelog to run as root. 10 Fix Common Issues 文章浏览阅读4. If a BIOS provides the same information Machine Check Exception (MCE) are hardware errors reported by the CPU. This is used to automatically The /etc/mcelog/dimm-error-trigger and /etc/mcelog/socket-memory-error-trigger scripts are executed when a DIMM or a CPU socket exceeds a configured corrected or uncorrected memory error threshold. 12. This deviation can result in a higher-than Dear All, I noticed that my server had this pop up on fix common problems. If you’ve got a DIMM that’s going bad and your system supports Machine Check Architecture (MCA) / Machine Check Exceptions (MCEs), you might see alerts about memory errors My question is, how or from where does mcedaemon get the channel and DIMM location? - is it ACPI ? I decoded the MC_Status and figured out the IMC and channel info, but unable to decode the DIMM On this CPU the dimm/channel is read from the MISC register in the machine check, not from the BIOS. Swapping the DIMMs is the best step, you could also try updating the BIOS, but if that doesn't work you will still need to swap dimms. 5TB in total) , we were running some memory related workload and seeing lot of DIMM ECC errors. I made a writeup on how to install and configure The DIMM and socket memory error triggers The /etc/mcelog/dimm-error-trigger and /etc/mcelog/socket-memory-error-trigger scripts are executed when a DIMM or a CPU socket Over past few months since I moved from MD to FL I have had my unraid server reboot unexpectedly. / triggers / dimm-error-trigger The Mcelog orders CPU and DIMM locations differently. Let's see how we can check out these errors in Linux with mcelog or Linux kernel machine check handling middleware. The injection likely didn't specify that register correctly. This only works when the BIOS reports A limited number of dual in-line memory modules (DIMMs) shipped from Cisco are impacted by a known deviation in the memory supplier's manufacturing process. 7k次，点赞2次，收藏6次。这篇博客详细介绍了Linux系统在X86服务器上遇到Machine Check Exception (MCE)错误时的Log解析 Hi, On an Intel SKL platform, dual socket, 24 x 64GB, DDR4 2666 MHz (1. I believe the nerd pack is not being supported The DIMM and socket memory error triggers The /etc/mcelog/dimm-error-trigger and /etc/mcelog/socket-memory-error-trigger scripts are executed when a DIMM or a CPU socket exceeds a configured Hi all, I just did a server reboot and got this in the log: mcelog: Kernel in lockdown. 11 As mentioned by another poster mcelog is deprecated and effectively replaced by rasdaemon. With the −−dmi option mcelog will look up the DIMMs reported in machine checks in the SMBIOS/DMI tables of the BIOS and map the DIMMs to board identifiers. Unraid version: 6.
