Recent Parity Rebuild - Machine Checks Event(s) detected (6.12.13 on HP Z800)

Featured Replies

Hi all,

 

I have just completed a parity rebuild during which a few UDMA errors were detected. 

Fix Common Problems plugin has detected an MCE - it suggests loading diagnostics here and asking for support from the community.

 

as such, could someone take a look at the diagnostics and advise me what action I should take from here.

Thanks Guys,

 

GT

It appear to be a RAM problem:

 

Oct  8 04:29:22 XEUS mcelog: corrected Socket memory error count exceeded threshold: 300 in 24h

Not just CRC errors, disk 10 appears to be failing:

 

Oct  8 10:57:24 XEUS kernel: critical medium error, dev sdb, sector 7310380208 op 0x0:(READ) flags 0x0 phys_seg 21 prio class 2
Oct  8 10:57:24 XEUS kernel: md: disk10 read error, sector=7310380144

 

Run an extended SMART test.

Does this mean the memory is failing and needs replacing, or should I just monitor it??

Will do!

yeah, this drive is pretty old. I have a new 12TB coming in a couple of weeks to replace it with - do you think it is safe to continue using this drive till then (there's nothing stored on it currently). 

 

Lastly, I want to learn more about diagnosing problems - is there a Noob guide/FAQ on how to go about interpreting these diagnostic files??

 

cheers,

It would be better to try and see if it's a specific DIMM and replace it.
