After updating through the GUI, does the tower need to be restarted for the update to take affect? I hate to reboot unless absolutely necessary. Thanks, craigr

Got the new motherboard. ubuntu@ubuntu:~$ cd /home/ubuntu/Desktop ubuntu@ubuntu:~/Desktop$ sudo ./ecc_check 5004-5007h: 10 0 61 3 5008-500Bh: 10 0 61 3 Looks like everything is in order now Thanks guys, craigr

Just sent an email to support: We will see. craigr

Quick question and sorry if it's already been asked. Is it possible that a disc that is not part of the array can still contribute to a "user share?" I would like to have my SSD drive be part of the Media share, but not part of the array. Thank you, craigr

I have had an SSD in my array since day one mostly for data that my theater media wall uses (tons of small files and the drive has to be accessed and "spun up" often). It's only a 64gig drive. I just stumbled on this thread where the question is brought up as to whether or not data can be properly rebuilt if a drive is lost if an SSD is part of the array: https://lime-technology.com/forum/index.php?topic=42961.0 So could someone please tell me if my data is safe or not with an SSD drive as part of my array? If not I will have to figure out an alternative quick. Thanks, craigr

That's an excellent choice; a good price; and supports ECC memory and your current CPU. I ordered the board. Wound up getting it on eBay from Newegg though. Price was much closer after Provantage shipping and I had 10% off gift cards for eBay. This will only leave me with one open expansion slot. I hope I don't need more slots in the future... Thanks for all the help! craigr

O fthe two Supermicro boards I have found, the X10SLL-F would be my preference due to the expansion cards layout. It seems Provantage has the cheapest price I can find so far. Anyone know of a cheaper place or other board options with my existing hardware? http://www.provantage.com/supermicro-mbd-x10sll-f~7SUPM424.htm craigr

Thanks guys. The drive seems fine and has been performing flawlessly with no further errors. I also noticed that four of my other 4TB drives had very high "UDMA CRC Error Count" as well in their SMART reports... I upgraded and added my cold spare 4TB drive to the array and two new 5TB drives (added 3 more drives total). After the upgrade unRAID would not see some drives once booted and the drives it saw were different on each boot. I split my 12 volt rails up differently and I have not seen anymore errors after that. I suspect that I had a bad power connection to one of my splitters or that my PS actually has more than one 12 volt rail even though it is speced as having a single 12 volt rail. Thanks for all the input. craigr

I just migrated away from AMD because of many reasons including the high power consumption. I have been building PC's for more than 20 years and I think Asus used to be a good brand, but mos everything I have gotten of theirs over the past 10 years has been junk or just one step above junk. I've considered getting an Asrock board, but the price savings over Supermicro is negligible so I will most likely stick with the better brand. Thanks for you input though. craigr

Thanks for this. I had found this link in my search to test ECC and was planning on trying. But since my BIOS actually reports no ECC I think it's highly unlikely that ECC is enabled. Add to that the chipset does not actually utilize ECC function and I think I just don't have ECC capability on my present hardware. Best, craigr

I think you are correct. I can still return my C7Z87, though I got it for a really good price. What all Supermicro boards will work with my existing hardware that support ECC? I'm having trouble sorting through the options with "Cxxx chipsets"... So far I have found the X10SLL-F and X10SLA-F. Are there any others? I wish there were any easy way to find Supermicro baords that support my CPU and ECC memory that actually utilize the ECC capability. Thanks again for your help craigr

Here is the current manual: http://www.supermicro.com/support/resources/results.cfm Page 1-7 Page 1-3 Page 1-4 Or maybe Supermicro just made it "support" ECC in the sense that the board will work with Unbuffered ECC but not utilize the ECC? Seems strange that in the BIOS it says anything about ECC than and that my RAM is "non-ECC." This is wonderful Thanks for your help, craigr

Actually, that used to be true, but a BIOS update allows for ECC support now. It only supports "Unbuffered ECC or non-ECC." I think that if the MB didn't support ECC that the system would not post at all? craigr

The problem is that the memory is reported as Hynix ECC in Memtest, but I think that is just the DMI. In System Overview my RAM shows up as having "Total Width: 72 bits; Data Width: 64 bits" which would be ECC. However, under System Overview it also reports the memory as "Error Correction Type: None." In my BIOS the memory is reported as "non-ecc" and I don't know why. This is frustrating. I don't know if ECC is enabled or which info to trust craigr

That is what I am afraid of. I don't think the later versions of Memtest include this capability. I was looking for ECC info in Memtest and didn't see it. It seems strange that memtest dropped this feature. Am I wrong? craigr

Quick, but maybe not simple question. When system Profiler reports "Error Correction Type," is this reporting that ECC is enabled, or only that the RAM supports ECC? I want to be certain that ECC is fully enabled on my system and not just that it has the capability. Thanks, craigr

Thank you. That is what I thought. What I found alarming was that it seemed to happen suddenly along with unRAID reporting 45 errors. Best, craigr

Just installed on unRAID 6.1 and everything looks good. Thanks for this. craigr

So a few days ago I noticed that one of my 3TB WD WD30EZRX-00DC0B0 had 45 errors in the unRAID MAIN page. Ths was just after upgrading my MB and CPU a few days earlier. I unplugged and replugged the SATA and power cables on the drive. I did a parity check that resulted in zero errors. I then moved all the data off the drive and ran a preclear on the drive. The preclear found no errors. Below is pertinent SMART details: # Attribute Name Flag Value Worst Threshold Type Updated Failed Raw Value 1 Raw Read Error Rate 0x002f 200 200 051 Pre-fail Always - 3156 3 Spin Up Time 0x0027 184 178 021 Pre-fail Always - 5800 4 Start Stop Count 0x0032 097 097 000 Old age Always - 3005 5 Reallocated Sector Ct 0x0033 200 200 140 Pre-fail Always - 0 7 Seek Error Rate 0x002e 200 200 000 Old age Always - 0 9 Power On Hours 0x0032 070 070 000 Old age Always - 22563 (2y, 210d, 3h) 10 Spin Retry Count 0x0032 100 100 000 Old age Always - 0 11 Calibration Retry Count 0x0032 100 100 000 Old age Always - 0 12 Power Cycle Count 0x0032 100 100 000 Old age Always - 371 192 Power-Off Retract Count 0x0032 200 200 000 Old age Always - 173 193 Load Cycle Count 0x0032 200 200 000 Old age Always - 2860 194 Temperature Celsius 0x0022 123 112 000 Old age Always - 27 196 Reallocated Event Count 0x0032 200 200 000 Old age Always - 0 197 Current Pending Sector 0x0032 200 200 000 Old age Always - 0 198 Offline Uncorrectable 0x0030 200 200 000 Old age Offline - 0 199 UDMA CRC Error Count 0x0032 200 200 000 Old age Always - 0 200 Multi Zone Error Rate 0x0008 200 200 000 Old age Offline - 5 Done What I find strange is that there are no reallocated sectors or events, but the raw read error rate is 3156 and the multi zone error rate is at 5. I have seen no other errors since running the preclear and the drive passed preclear. I have copied nearly 3TB of data to the drive and it's now nearly full again with no further errors. Thoughts? Thanks guys, craigr

Thanks for this script. It seems to do the job perfectly. Best, craigr

THANK YOU both very much. Best, craigr

Could someone please tell me how to install Screen on unRAID 6.1 please? I found the "nerdPack, but I don't want to install all those plugins, just Screen. https://lime-technology.com/forum/index.php?topic=37541.0 Thank you, craigr

Your SSD is able to go into 'standby' mode, presumably lower power, that's what spindown means for such devices. EXCELLENT. I am glad to see this back. Thank you, craigr

Interesting. Could you please explain? Best, craigr Or 3) The stripe containing the parity mismatch got written, thus restoring correct parity.

So I ran the parity check again and it finished this time with zero sync errors. This tells me one of two things: 1) Either unRAID has a bug and when "Write corrections to parity disk" is unchecked, the parity drive is still being written to. 2) Or the first parity check detected sync errors that did not exist. Best regards, craigr
