Hardware Error


While running I'm getting the following message found in the messages file after a reboot:

Mar 15 21:57:09 MySystem kernel: [Hardware Error]: Machine check events logged

Where can I find the information on whatever error this concerns? I am running the following hardware:
ASRock X99 Extreme4
Intel Core i7-5820K (liquid cooled)
64 GB DDR4 RAM (ran memtest looking for error and found none)

Running CentOS 6.8 x86_64 completely updated

This custom system is less than 6 months old and I want to know some details so I will know what is being told to me when I take it back.

TIA

Have you checked the logs in /var/log (I just checked; /var/log exists on CentOS. I'd look first at /var/log/messages.

You can also use SystemD tools to view the logs, but I don't have much experience with them: https://www.digitalocean.com/communi...e-systemd-logs

I saw the message mentioned above in /var/log/messages. I also saw the same message in dmesg. But there was no explanation as to what or where (I assume the when was the time stamp on the message)

Now, let me throw another wrinkle into this...
The message appeared again Mar 17 13:41:00 as the last line in messages. The prior lines in the messages has to do with smartd; ntpd; with the last time stamp of 13:37:24.
But the system did not crash or lock up, it is currently running command line.

There are other dates and times (starting Mar 13) where the message appeared and I would venture a guess that the system locks up 75% of the time when the message appears.

TIA

I reckon to give anybody a snowball's chance of helping you you're going to have to post the error message and include, say, at least twenty messages prior to it as well. Any clues are likely to before the actual machine check.

Play Bonny!

CentOS 6 is not systemd.

You can post the contents of the /var/log/mcelog file or the output of the command

The mcelog is showing a 0 (zero) length and is dated Mar 13 23:39. I have no idea why it is not working.

Here are some of the messages just prior to the error message at Mar 18 17:58:30:

You're running smartd 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-642.15.1.el6.x86_64] (local build)

sda and sdb are both 120Gb SSD drives.

Both SSDs give messages:

When I Google this I get Smartmontools ticket #248 which was logged four years ago.

What I gather from this, SMART attributes are not standardised across both SSDs and HDDs. As you are running a now rather old version of smartd (5.43 as mentioned in the fault ticket) maybe you should be running something more current, looks like 6.5-3? I'm not sure. Perhaps a sysadmin type could either confirm or correct my findings, not me Chiefy, I'm engines. (hardware)

I've removed smartmontools (the package for smartd) while I look for a replacement - seems all of the repositories only have smartd 5.43.

While we are on this portion of the problem, I must say that fdisk invoked during installation when I created all of the raid1 file systems does not like 4 TB hard drives. The install allowed me to make 5 partitions defined as LVM physical volumes and raid1 them. I am still at a loss as to how it did it. Here is what I'm talking about:

When I enter fdisk -l /dev/sdc I get the following to sysout:

WARNING: GPT (GUID Partition Table) detected on '/dev/sdc'! The util fdisk doesn't support GPT. Use GNU Parted.

Disk /dev/sdc: 4000.8 GB, 4000787030016 bytes
255 heads, 63 sectors/track, 486401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

Device Boot Start End Blocks Id System
/dev/sdc1 1 267350 2147483647+ ee GPT
Partition 1 does not start on physical sector boundary.


But when I issue a pvs command I see all 5 partitions (md4 - md8):

PV VG Fmt Attr PSize PFree
/dev/md1 vg_jpdopsys lvm2 a--u 63.93g 29.93g
/dev/md2 vg_jpdswap lvm2 a--u 23.98g 7.98g

/dev/md5 vg_jpddbdata lvm2 a--u 841.38g 609.38g
/dev/md6 vg_jpdsysdata lvm2 a--u 841.38g 761.38g
/dev/md7 lvm2 ---- 841.38g 841.38g
/dev/md8 lvm2 ---- 841.38g 841.38g


Could all of th9s be a part of the issue?

TIA

No, because if you read the warning message fdisk does not support GPT disks. Look at the output of the command

parted -l

No idea why a MCE is not be logged to the mcelog file. At the moment I suspect it is a smartd version problem. Might try a recent live version if possible like mint to see if you have the same problem.

I'm going to work with a friend of mine who is way ahead of me on hardware to see if we can isolate this issue.

I spoke to another friend and she suggested that I try CentOS 7 because it has a better error reporting proceses. But she suggested a complete reinstall.

I'm also going to look for some documentation for parted for fdisk users.

TIA

gdisk is similar to fdisk but is just for GPT partitions.

OK, Several stress test programs were used (tested RAM; video card; CPU loads; disk drive issues) and none failed - but let it be said that all of the tests were run using Windows. So I'm back to thinking that Windows is a lot more tolerant of errors than Linux is.

I'm going to try gdisk and I'll get back to you.

In the meantime I've removed smartmon and removed all partitions from both 4TB disk drives.

Not sure what to say other than I performed all of the disk configuration using gdisk and it was actually more simple than using fdisk. I noticed that there is no 'extended' partition just 5 sequentially numbered partitions. The md devices are still doing their resync, but the machine has been up all day so far.

Why didn't the CentOS installation program 'see' the 4 TB hard drive and invoke the gdisk program?

Looking at /var/log/messages I still see the message (3 times):
kernel: {hardware Error]: Machine check events logged

But no machine crash - yet.

OK, Let me say that what appeared to be a hardware error probably isn't. Using the gdisk program solved all of my partitioning problems on those 4 TB drives.

After that was complete and all of the resync processes were done, this machine received a abort message after I restarted this machine:

Source Problem Last Occurance
gamin Process /usr/libexec/gam_server was killed by signal 11 (SIGSEGV) 2017-03-25 00:50

Should I stay here? Move over to some software forum? Go to a CentOS site?

TIA
