Well, that’s a perfectly valid way too, but you can just set t to its previous value too. I forget what it is, it the command will tell you when you change the value what it was before the change.

Yup, I've done that too and I'm certain that value is listed in the instructions. For some reason I just like to reboot the system to ensure it is fully operational, not just to reset that value. I've run into the situation on many different computers where you make a change and 3+ days later your system reboots and something is wrong. Then you rack your brain to thing "what did I do and when did I do it?". So when I make changes, depending of course on the change, I like to reboot to ensure I didn't induce some failure. Again, that is just me.

Odd but like @Stux said, maybe a firmware difference. It's too bad they all were not a zero value but having a value in thiese Fields does not mean anything bad if all the other results are good. So if you ran a SMART Long/Extended test at the end and all the critical parameters are good then I'd say move forward and continue with your installation.

I also checked with SeaTools and it seems drives are ok. Although numbers Raw Read Error Rate number are now lower, from 9 figure to 5. Except for one drive where it is still 9 figure.

I noticed another strange number - Start Stop Count is not same for all drives, is this normal? They were together this whole time, I didn't even open case these days.

This is first report:

I noticed another strange number - Start Stop Count is not same for all drives, is this normal?
Seatools likely caused the descrepancy. It's nothing to be alarmed about.
Although numbers Raw Read Error Rate number are now lower, from 9 figure to 5. Except for one drive where it is still 9 figure.
The Raw Read Error Rate can be ignored if your drive always reports some wild number but you have no other errors. Check out my Hard Drive Troubleshooting Guide in my signature. If this value is always zero and now starts to creap up, you probably have an issue.

So everything looks good, that is great news. Ensure that you are running scheduled SMART Short and Long tests, they likely will save your rear.

Is the burn-in testing procedure the same for SAS as it is for SATA disks? The reason I ask is I found a script by Spearfoot that works great on SATA disks (I've got it running under Ubuntu on six SATA disks that's probable nearing the end of the badblocks portion), but he indicated it was never tested on SAS disks and that commands are different. The first issue I had was it wasn't creating proper log files - as it turns out, that part was due to different naming conventions in the '=== START OF INFORMATION SECTION ===' portion of the SAS and SATA disks, which are different - the script is looking for "Device Model", "Model Family" and "Serial Number", when the relevant values are "Product", "Vendor" and "Serial number" (note the lower case 'n' in 'Serial number' - that's how it is in the output for a SAS drive *shrug*. I'm not sure if the script is running properly, but because the log file doesn't update after the initial creation (It should, in theory, update within two minutes or so of the initial run), I have a suspicion something's tripping it up.

Any thoughts?

You don't need a script to run any of these tests on any drive, I just finished doing these test via the manual way of following the first posting in this thread. I do know that some interfaces do not support smartctl but you can easily find that out. Badblocks should be well supported.

I realize a script is not needed, but let's be honest, while running each command individually certainly works, it's a whole lot more streamlined (especially if you're testing more than one drive) when you have a script that runs the commands and outputs a file for the drive than to run a command and wait, run the next command and wait more, run the next command and wait yet some more, run badblocks and wait for it to complete, then re-run the SMART tests (if desired/needed) and then finally get the smart status.

Take the SATA drives I have testing now using the script - when I started the script, the extended test, which I believe was going to take six hours to run, finished after midnight, after I'd gone to bed. Because I was using the script, rather than having 7+ hours if idle time between the extended test and starting badblocks, it kicked off the badblocks testing when the extended test was complete, thus getting at least a 7 hour 'head start' on running the test.

I do understand that running a script can make testing time take less time overall if you are not available to manually check results and launch the tests but that dead time can also be valuable as well to check to see if your hard drives are constantly spining up/down or head loading is incrementing, so it's not a total waste.

If you do test out the script with SAS drives, post your results on how the script worked.

The problem that I'm finding, at least with this script, is that since it's meant for SATA disks, things don't line up and it doesn't work. Part of it seems to be that the SAS drives have no SMART capabilities, or at least none that can be queried by smartctl using 'smartctl -c /dev/da4' (The help menu seems to indicate that the 'capabilities' switch only applies to ATA and NVMe), so the script can't poll the status of the previous test (It uses 'smartctl -c /dev/"$Drive"' to determine how long a test is likely to run and if it has completed before moving on). On the manual testing side, while the short test works on the SAS drives, conveyance does not appear to work (no apparent errors, just nothing happens, nothing new in the SMART log), and apparently the long does not (at least not with the same command as the SATA disks - I get 'Long (extended) offline self test failed [unsupported field in scsi command]').

It seems like smartctl was not intended for use with SAS disks, although it does work with them for certain aspects. From a lot of what I've read, it seems like the controllers on SAS disks are a lot smarter with regards to errors than SATA disks, so are the extended tests really needed on them, or would running badblocks (with whatever the right command would be to get it to run right on the SAS disks) followed by 'smartctl -a /dev/da4', reviewing the data in the 'Elements in grown defect list' and probably the 'Total Uncorrected Errors' values be plenty sufficient?

Moved this to its own post in case it was glossed over as part of a read post.

I bypassed the smart testing (for now, at least) and tried running badblocks on the drives and what I got was this:
Code:
root@freenas:~ # badblocks -b 4096 -wsv -o "da4.bb" /dev/da4												
Checking for bad blocks in read-write mode			
From block 0 to 488378644							
Testing with pattern 0xaa: set_o_direct: Inappropriate ioctl for device										
 3.96% done, 5:34 elapsed. (0/19329273/0 errors)

On the SATA disks, I'm seeing '(0/0/0 errors)' and 0 byte size 'bb' files, but running on the SAS disks, the 'bb' files were quickly growing and exceeded 100MB each in short order. It seems rather unlikely that all eight drives have that many errors, considering SMART reports 'Elements in grown defect list: 0' on all of them and all but one show 'Total uncorrected read errors 0', all other 'total uncorrected' for all drives are 0 (The one that doesn't say '0' says '7'). That being said, I'm guessing this has something to do with the 'Inappropriate ioctl for device'?

Edit: I may have found the problem. I did some reading and found a thread on superuser.com about badblocks, where it was stated that setting the block size to something other (usually larger) than the disks block size can compromise the results with false positives. I ran 'diskinfo /dev/da4' and determined that the disks reported block size was 520 bytes (I had tried badblocks with the default and 512bytes as well, both gave the same results as with 4096). I then ran badblocks using badblocks -b 520 -ws /dev/da4, and this is what it's looking like so far:

Code:
root@freenas:~ # badblocks -b 520 -ws /dev/da4 > bb2.log
Testing with pattern 0xaa: 2.42% done, 5:04 elapsed. (0/0/0 errors)

If I were you I’d look at modifying the disks block size back to 512. If possible.

Iirc 520 is the NetApp block size and I don’t think it’s a good idea to run 520 block size disks with ZFS.

In order to troubleshoot your issue you should open a new thread, specify your hardware. I agree with @Stux as well.

As for SMART conveyance tests, even my SATA drives do not support this test so it's not just your SAS drives.

The reason to run a Smart long test before badblocks is to ensure the drive doesn't have any obvious flaws up front due to possible shipping damage. I mean, you don't have to do it and you can do it after badblocks if you like. These are just recommendations on how to test your hardware before placing it in a functional system.

Thanks. The original posts were more related to getting the tests to run on the drives, which is in line with the purpose of the thread. Now that I'm pretty sure I determined the cause of the issues I was having (I'm assuming the reason for the 'errors' is that the 512, 1024 and 4096 block sizes didn't line up evenly with the 520 byte blocks). Now that I've gotten where I am, I'll see what I can do with what I have and if I need more, then I'll open up a new thread. Hopefully what I've posted will help someone if they should stumble across similar issues.

I finally got done with badblocks running on my 'new' SAS disks - 500+ hours in and the first four were like 50% through the last write sequence, which was crazy slow. So I started digging around because that just didn't seem right. I finally found a single lonely post buried in the middle of this 23 page thread where someone else saw the same thing with some new WD SAS disks, and he found that the writeback cache was disabled - after enabling it, badblocks took off. So I checked the disks and sure enough, writeback cache was disabled. I enabled it and they took off like a rocket. Might be beneficial to add a blurb like 'If it seems like badblocks is going way too slow, check the writeback cache on the disks - if it's disabled, enable it' to the OP so that the info is up front and doesn't get buried in the thread again.

You need to change the block size on your disks. Here is how:

Just a quick question, how long on average does badblocks take on 4tb (WD Red) drives?
