Preclear.sh results - Questions about your results? Post them here.

I hope I within topic here, but even if I'm not, this is probably the place to do it rather than starting a new thread.

 

I found that preclear absolutely wrecked the speed of my array while it was happening.  I stopped it, and the array sped back up. 

 

I'm using the onboard SATA ports.  Could this be attributed to cruddy onboard sata?  Would I be better off buying a SAS HBA and feeding off of that instead?

Unless you're using a very slow CPU [e.g. a single-core Atom or a very old Pentium] this should not be the case.    And in general the onboard SATA ports are the best ones to use.    So ... check the BIOS to confirm you have the SATA mode set to AHCI.

No.  Shouldn't be a CPU issue.  I'm running this:

 

root@maxi:~# cat /proc/cpuinfo | grep "model name"

model name : AMD A6-5400K APU with Radeon HD Graphics

model name : AMD A6-5400K APU with Radeon HD Graphics

root@maxi:~#

 

And my drives are all (except the 500gig one I was replacing):

 

root@maxi:~# smartctl -i /dev/sde | grep Model

Device Model:    WDC WD30EFRX-68AX9N0

root@maxi:~#

 

I'm just wondering if the onboard controller might have been getting overwhelmed. 

 

I'm currently in process of rebuilding on to the new 3TB drive (from the 500GB), and it's running at about 100MB/s.

Well, the rebuild is going at a VERY good rate, so all's working well now.

 

But a single pre-clear should NOT have caused the array to run notably slower than normal.    I've done two pre-clears at once with my Atom and still been able to use the array at normal speeds.

 

One of life's little mysteries I suppose.    See if your next pre-clear has the same issue ... but in any event, they're such a rare activity that I wouldn't worry about it as long as everything else is working well.

Any issues with these two new 4T's?

They look fine.    The first one has a relatively low value for the ECC_Recovered parameter, but that's an informational value, not a critical SMART parameter.    But the key values are all okay; and neither has any reallocated sectors ... so you're in good shape.

Something I should keep an eye on?  Was going to make this one the parity becuase of the speed...

Hey guys, it's been quite a while since I've added any drives to my array. I just finished preclearing a couple Toshiba PH3300U-1I72 3TB drives, here are the results.

 

Everything seems okay to me, but I'm interested in other opinions.

 

Thanks for the feedback!  ;D

The report looks good except I don't like the High Fly Write value.

 

I concur.  It's strange to see a brand new drive with 93 High_Fly_Writes already, and no other adverse numbers.  It could possibly be a faulty sensor, but I'd monitor this drive more than normal, because it *may* have mechanical issues that will shorten its lifetime.  But so far, I have never heard of any drives that have failed, whose only SMART warning was a large number of High_Fly_Writes, so we don't want to unnecessarily alarm you.  Right now, the drive is fine, and may be fine for years, but I would not be surprised if this drive failed sooner than others of the same model.

Hi all!  i was having parity errors, ran smart reports on all 20 of my drives, and  3 of my drives resulted in having pending sector reallocations.  i cleared data off all 3 drives, and am in the process of preclearing

 

here's the results of the preclear...looks like all 41 pending reallcoations have been reallocated.  i should add its quite an old drive...

 

any recommendations?  its out of warranty... should i add back to my array and keep an eye on it?  ditch it?  i guess its a judgement call but advice is welcome!

The drive looks fine -- in fact the "pending" sectors tested okay, so SMART didn't even reallocate them (you still have 0 reallocated sectors).

 

It's also not all that old a drive -- at least not in terms of power-on hours.  It's got less than 15,000 POH ... I've got drives in my array with over 40,000 hours.

 

As you noted, it's a judgment call whether or not to use them.  Personally, I'd just use it for a backup drive.  Probably 1/3 to 1/2 of my backup drives are repurposed drives like that -- either had minor issues (like your drive), or were replaced with larger drives.

hi there!  i have a second drive's preclear result (mine is also the previous post).  thought it might be best to have these results in a separate post.

 

overall i think these look okay, but there is one error called 'reported uncorrect' which i've never seen before... think its a concern?  this drive used to be my parity drive, and i recently removed it to upgrade to a 4tb parity.  my plan was to add the former drive to the array (ie add this precleared drive to the array) but just a bit unsure what this indicator means.

SMART parameter 187 reports the # of read errors that could not be corrected via the ECC code.

 

Your report still shows a good value for this (99), so I'd just consider it an anomaly and not worry about it.

 

Seagate reports a lot of parameters that other drive manufacturer's don't show ... and most of those extra ones are of little-to-no utility for really analyzing a drive's status.  [but they cause a lot of worry  :) ]

 

r.e. being a champion for backup => I certainly believe in backups.  My point r.e. these drives is that you've had issues with them;  they still look okay; but your "confidence" level is probably low.  Using these for backups reduces the number of backup drives you need to buy if you don't already have enough.    I know many folks don't bother to backup their arrays -- that's simply a personal choice.    I tell all my friends/clients a very simple rule:  Always assume your system is going to have a catastrophic failure  at midnight => if there's anything you're going to be upset about losing when that happens, back it up;  if not; don't worry about it.

thanks Gary... that's probably a good way to look at backups

 

for me, i tend to burn to dvd almost everything before it goes on my server... the exception is super large movie files....so if i had a catastrophic loss, i could reload the most important parts off dvd but it would be a chore for sure.  but at least its something

for me, i tend to burn to dvd almost everything before it goes on my server

 

I did the same for several years -- still have 6 400-disc folders full of DVDs.    But as the hard drives got large enough, it was FAR more convenient, and less expensive, to simply copy everything to a backup disk before copying it to the servers.    A TB of disk space costs ~ $50 (or less) => but can hold over 200 DVDs.  So if you paid $0.25/blank DVD, you'd be spending the same amount -- and you'd still have to burn all the DVDs.    I simply keep my current backup disk in a caddy; copy everything I'm adding to the server to the backup disk;  and when the disk gets full, simpy put it in a case (I use WiebeTech DriveBoxes [ http://www.officemax.com/office-supplies/safes/security-fire-safes/product-prod5014223?cm_mmc=Googlepla-_-Office%20Supplies-_-Safes-_-Security%20Fire%20Safes&ci_src=17588969&ci_sku=23619602 ]; and pop in the next backup disk.
