jbuszkie Posted October 11, 2013 Author Share Posted October 11, 2013 How long have some of your 4T drives taken? It's trending that mine will be well over 24hrs.. Possibly closer to 48! The last 4TB drive I ran it on took 36:41:32 41:34:51 !! :-) But no errors, at least! Quote Link to comment

grither Posted October 16, 2013 Share Posted October 16, 2013 Ok here's a second preclear on the drive above.....if i'm reading correctly, the first clear above resulted in 3 pending sectors at the end....when i started this second preclear, there were 5 at the start, 0 after the zeroing, but then 6 at the end. so it seems like bad sectors are popping up, getting fixed, but then new ones are popping up drive is out of warranty. should i run a third preclear? i suspect i know what the outcome will be! ========================================================================1.13 == invoked as: ./preclear_disk.sh -M 4 /dev/sdj == WDC WD20EARS-00S8B1 WD-WCAVY2471414 == Disk /dev/sdj has been successfully precleared == with a starting sector of 64 == Ran 1 cycle == == Using :Read block size = 8225280 Bytes == Last Cycle's Pre Read Time : 7:53:24 (70 MB/s) == Last Cycle's Zeroing time : 6:55:29 (80 MB/s) == Last Cycle's Post Read Time : 15:27:00 (35 MB/s) == Last Cycle's Total Time : 30:16:55 == == Total Elapsed Time 30:16:55 == == Disk Start Temperature: 30C == == Current Disk Temperature: 37C, == ============================================================================ ** Changed attributes in files: /tmp/smart_start_sdj /tmp/smart_finish_sdj ATTRIBUTE NEW_VAL OLD_VAL FAILURE_THRESHOLD STATUS RAW_VALUE Temperature_Celsius = 115 122 0 ok 37 Reallocated_Event_Count = 90 95 0 ok 110 No SMART attributes are FAILING_NOW 5 sectors were pending re-allocation before the start of the preclear. 5 sectors were pending re-allocation after pre-read in cycle 1 of 1. 0 sectors were pending re-allocation after zero of disk in cycle 1 of 1. 6 sectors are pending re-allocation at the end of the preclear, a change of 1 in the number of sectors pending re-allocation. 107 sectors had been re-allocated before the start of the preclear. 112 sectors are re-allocated at the end of the preclear, a change of 5 in the number of sectors re-allocated. ============================================================================ ============================================================================ == == S.M.A.R.T Initial Report for /dev/sdj == Disk: /dev/sdj smartctl 5.40 2010-10-16 r3189 [i486-slackware-linux-gnu] (local build) Copyright © 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Model Family: Western Digital Caviar Green (Adv.

binhex Posted October 16, 2013 Share Posted October 16, 2013 ditch that drive, if its still got 6 pending sectors after 2 pre-clears there is little to no chance its every going to go to 0, i personally wouldn't even let that drive be within 30 metres of my array :-) the question you got to ask yourself, is even if it did go to 0 would you REALLY want to chance it, possibly if it went to 0 after 1 pre-clear.

garycase Posted October 16, 2013 Share Posted October 16, 2013 I agree I wouldn't use it in your array. Format it, and use it for backups. Quote Link to comment
grither Posted October 16, 2013 Share Posted October 16, 2013 Ok I agree. Started a third preclear just out of curiosity before I got your responses. I think even if the sectors are cleared I will remove and use for backup Quote Link to comment

dcoens Posted October 20, 2013 Share Posted October 20, 2013 Can someone validate that by five preclear disks are good to go with the preclear process Thanks There is a start / report and finish I am not sure what I am suppose to look for. dcoens_preclear_reports.zip Quote Link to comment
garycase Posted October 20, 2013 Share Posted October 20, 2013 Can someone validate that by five preclear disks are good to go with the preclear process Thanks There is a start / report and finish I am not sure what I am suppose to look for. They all look fine. You're looking for all zeroes in the reallocation summaries; and no bad SMART values. With Seagate disks there are a few values that get reported that you won't see on most other brands; but you don't have anything in these reports to be concerned about. Quote Link to comment

garycase Posted November 5, 2013 Share Posted November 5, 2013 It's not perfect, but it's okay -- it passes SMART and only has 3 reallocated sectors ... and no new ones required reallocation during the pre-clear. I'd be more inclined to add it to your backup pool ... just use it as another backup disk; but if you already have enough backup disks, then it's okay to add it to your array. Quote Link to comment
maximusfacq Posted November 12, 2013 Share Posted November 12, 2013 I'm running into a strange issue with a preclear on a brand-spankin' new 4TB Red Drive. So far, it appears to be a communication issue with the drive. I have tried: swapping cables, 3 different ports on the controller card (AOC-SASLP-MV8 - .21 Firmware) (All 3TB Reds and a 3TB Black are connected and functional on this controller), and 2 different ports on the motherboard (Gigabyte Z68MX-UD2H-B3/Z68MX-UD2H-B3, BIOS F10 09/01/2011). Each time, the preclear process fails. Below is a dump of the terminal session I was using for the preclear of the WD 4TB Red. Now, at first I thought this issue might be linked to the fact that I was using a 4TB drive. However, after the first couple failures with the Red, I received and unboxed the shiny new 4TB Black drive, that will become my new Parity drive. This one has run through the initial read and is 94% complete with writing 0's to the disk (Step 2). No issues whatsoever. The Red kept failing, much earlier in the preclear process. I expect the Black will complete as well. So, I'm thinking that it's just a bad controller or port on the drive. Perhaps Joe L. or someone else might be able to confirm my theory? I'd hate to have to RMA this drive. But, I'm not sure what else it may be and what other tests I might be able to do to confirm my theory. = Step 2 of 10 - Copying zeros to remainder of disk to clear it DONE = Step 3 of 10 - Disk is now cleared from MBR onward.

Joe L. Posted November 13, 2013 Share Posted November 13, 2013 If the disk stops responding (dos not even respond to an fdisk command) then you can't really do much. It could be the disk controller, the power supply, or anything connecting the drive to the MB. You seem to have eliminated the drive itself. (how many drives are you using? ) What SPECIFIC make/model power supply? How many splitters on the power cables are you using? , are you using drive trays? Quote Link to comment
maximusfacq Posted November 13, 2013 Share Posted November 13, 2013 Sorry my profile wasn't fully updated Joe L. I have resolved that issue. I'm leaning towards the drive because that's what's new, aside from the version of the preclear script that I'm running, and the fact that 4TB drives are a fairly new thing, still. I did just update from 0.9.8 to 1.13. I'd had no issue with the old script, but decided that being that we're dealing with these beastly drives, that it might be time to update. All that being said, there was only 1 more drive in the server than there had been, for the last year or so. And as far as I understand, the power supply I have should adequately support 10-12 drives. Currently, in the server, I have all drives drives listed in my profile, in addition to a 4TB WD Black drive. So, 6 drives in total. I am not using any splitters, as this power supply is modular. I only have enough cables plugged in to power 4 drives with their own power connection and 2 molex connectors that plugin to the SuperMicro 5in3. Because I have tried known-working cables and ports on the motherboard, and I've had no other indication of an issue, until now, the disk controller seems to be the most logical culprit to me. But, I'm coming here to seek the opinion of the experts, such as yourself, that have been at his for longer than me. So, feel free to continue picking apart my theory. I hope that between my updated profile and what's in this post, that all your questions are answered and you have further thoughts and/or questions. Thanks Much! Quote Link to comment
lumpumun Posted November 20, 2013 Share Posted November 20, 2013 Hi everyone, In attachment are the results of a PreClear proces. There are 7 sectors pending for allocation. No SMART attributes are FAILING_NOW. Not sure what to make of it. Is someone able to help me out on this? Thank you. Herman sde_preclear_report.pdf Quote Link to comment
