It gives me this:
A 700W power supply should be plenty, correct? I wouldn’t think the size would be an issue now unless the power supply itself is going bad…
Thanks!
Hmm. Swear that’s worked before.
Elevate to a root shell with sudo su and then try:
for i in /sys/class/scsi_host/host*/link_power_management_policy; do echo max_performance >$i; done
Unless it’s a really low-quality 700W that can’t actually deliver, 3 drives shouldn’t be anywhere near enough to upset that drive. What we’re doing with the script above is setting the policy on the SATA link itself to never go to a sleep/idle state.
This time it didn’t return anything. I ran it 2x to make sure I did it right the first time…
Thank you!
That should mean it took - you can check with
cat sys/class/scsi_host/host*/link_power_management_policy
And see if it comes back with maximum_performance for all of them.
OK, figured out what was wrong. missed the “/” at the very beginning of the location… Now I get:
Exactly what you expected…
If this was the issue, should the degrade disappear by itself?
Thank you!
It’ll stop reoccurring. Do a zpool clear and then a scrub and see if it reoccurs. Some of the issues I saw that were related to this also had older AMD based builds, so I’m wondering if something in the SATA controllers in those systems were exposing an oddity.
Default setting for power control is to follow the BIOS/system defaults, and if those are a bit off, that might be causing the failed writes.

Well, I have done a number of things to see what would happen.
I ran another complete surface scan (took about 8hrs or so) on the disks with the WD software which turned up with zero errors.
I loaded the drives (my data pool drives and my boot pool drive) into another computer I have that is much newer and built for much heavier lifting. It did seem to have less errors but they did not completely go away.
I have abandoned the back plain altogether because it did seem to cause more errors.
I have all drives wired directly to the mother board. (back in the original computer).
I’m running a second scrub in 2 days. Ran one on the newer computer and now running another on the original computer.
I noted that there were several files labeled as possibly damaged during the first scrub. They were all in the backup of my one laptop so I tried to delete the complete backup. I was able to delete most of it but for some reason it would not let me delete the main directory and a couple sub directories. It kept telling me I did not have permission when I tired to delete them from my MacBook and when I tried to ssh in and delete them that way it kept telling me “invalid exchange”. I have no idea what that means and couldn’t find anything from searching… Anyway. I am not seeing any files listed as damaged so far during this latest scrub.
I am not getting any of the “Degraded” or “Faulted” messages on the drives but I am still getting checksum errors. After last boot (about 5-1/2 hours ago), I am up to 324 checksum errors on 2 of the 3 disks and 20 on the 3rd.
I also have 2 more 2T WD Black drives that I tried to setup as mirrored drives to create a second pool but it failed when I tried to set it up?!
Do you think that upgrading my pool to the latest ZFS version might help? I have not researched what the latest update was for, so I don’t know.
Thanks for all the help!!!
@HoneyBadger So, now the pool and a disk show degraded again. UGH…
I got this message. I don’t know if it helps at all. I’m not sure what it’s telling me.

Well, I don’t think it’s necessarily a hardware issue. I mean it could still be but I changed to my other computer and it is still getting checksum errors and lots of them…
I saw in the Truenas documentation that the checksum setting in each of the datasets should be set to “SHA512”. Do you think that is correct. I went ahead and changed all mine, but it seems to have made it worse instead of better…
This system is:
AMD Ryzen 7 5800X 8-Core Processor
Corsair Vengeance Pro 16GB x 4 (64 GB)
ROG STRIX X570-E Gaming Mother Board
Thanks…
Though you’ve done extensive testing & have validated using manufacturer software, I’m curious to the output of ‘smartctl -a /dev/sd#’ (replace # with relevant drive letter)… Maybe your drives are actually failing?..
Yes, maybe and I will try that. The curious thing is… They have exactly the same amount of errors. All 3 are exactly the same. Just seems a little weird to me. But who knows.
Thanks for your advice!

I’d actually argue that drive 1 & 2 do/did have a mechanical fault given the multizone failure being a non-zero value. I don’t know if these drives are in warranty, but given that output I’d try to RMA them.
WD in my experience are pretty reasonable & have rma’d drives with similar outputs for me, even though they ‘passed’.
Disk 2 is worst of the bunch with raw read error rate creeping up - it is already half way to hitting their failure threshold.
Disk 3 looks fine imo.
…uhh, I’d recommend starting to backup data.
Another thing to note, I see disk 2 is ~70k hours old, but last test successfuly ran was at 18k hours of life. Not sure if anything went wrong with your scheduled tests? Not sure if I’d recommend running full smart long tests on all of them for more recent test results or focus on backups asap.

I have opened a ticket with WD. If nothing else, I want their opinion on what is going on with these disks.
I have monthly Long smart tests scheduled and weekly short tests. I also ran long tests on all 3 of these disks manually when I started having these issues, so I don’t know why it would show the last long test was sooooo long ago… Doesn’t make sense!
Thanks for your input! I appreciate it.

Well, WD said they believe there isn’t anything wrong with the drives. Their comment was… If you ran our software and it passed, the drives are good.
They suggested that I reformat the drives and start over (which is where I was going next).
