The config here is 2 sets of 6 drives in RaidZ2. 1 set is all 4TB drives, the other is 2TB drives with exception of a single drive that has been moved to 4TB as it showed a SMART error last week and was replaced. The drive was replaced after an email indicating a smart long test error, resilver seemed to go pretty quickly but I can't be sure when it was done.

I'll note that the 1 drive above with checksum 5 (what does this number even mean) I THINK is the recently replaced drive.

Not really sure what's going on here and hope someone has some insight.

thanks

I would suggest you look through the logs and/or storage to map drive ID 'gptid/bed7d557-87af-11e8-bef4-0cc47a4b08a7' to a physical drive serial number. You can do a zpool clear from the CLI to stop this message, but keep an eye on your zpool status to make sure the errors aren't incrementing. It is possible there are issues with your replacement drive.

Chris Moore · Jul 18, 2018

The hardware described in your signature doesn't appear to match what you are discussing in your post because it says that you only have 4 drives.
Is there an update or is it different hardware?

We should probably look at the SMART status on both of the drives with CKSUM (checksum) errors. This error indicates that there was a data block that didn't match the checksum block. ZFS should have automatically fixed the problem and if it could not fix it, it should have warned you that there were permanent (I can't remember exactly how it says) errors in the affected files. I have been lucky to not have this happen to me, but I have seen other people on the forum with one or several files listed as being damaged. I would expect that your data is fine and this is just an advisory to let you know ZFS did the thing it is supposed to do. Looking at the SMART data is about trying to find out why ZFS needed to fix something.

After we look at the smartctl output for those two drives, we can probably clear this error, but you might want to do a scrub, just to be sure.

I hate to assume you know these commands, so I will list them:
- To initiate a scrub of the pool right now, from the command prompt: zpool scrub pool_name
- To clear those errors, but don't do it before some investigation: zpool clear pool_name
- To start a short SMART test of a given hard drive: smartctl -t short /dev/ada0
- To start a long SMART test of a given hard drive: smartctl -t long /dev/ada0
- To check the output of the SMART test of a given hard drive: smartctl -a /dev/ada0

If you are not sure how to interpret the SMART status, just post it up here in code blocks and someone will take a look at it.

Chris Moore · Jul 18, 2018

PS. The long test is best for testing to see if a drive is healthy or just pretending to be. What kind of drive do you have?

I'll take a peak when I get moment here (thankfully I have my VPN up now so as long as I get a min at work I can do that now)

Chris, yes you're right this hardware has been updated a bunch since I've updated my signature. Currently running a supermicro x9scl board with the 12 drives in two sets of 6. All drives WD Red drives. Some are 7200 RPM but the newest 4TB drives are 5200?

ECC RAM and the like. I really need to update that signature.

I'll get the output here in a few posted.

rwslippey · Jul 18, 2018

Ok, So Volumn status in the GUI shows exactly the same info. One drive shows checksum "5" and another drive (on the same vdev) shows checksum "1". It shows the resilver was completed on Saturday.

zpool status shows no know errors but also shows 2 drives with a checksum (1 with a "1" and the other with "5")

Should I start another SMART test. I have my automatic SMART tests configured as cyrberjock suggested here on the forums so it's not due for a few more days (22nd I think)
Or would it be better to do a scrub first. I can't remember the schdule but I followered his advice there too.

I am not sure what was suggested by @cyberjock but in this instance, we are trying to do a little troubleshooting to ensure that your system is healthy. I would say that you should run a long test on each of the two drives that are indicating a checksum error. That will take some time to complete, and when it is done, we should have a look at the test results.

This must be the new drive that you mentioned because

rwslippey said:

The checksum errors are probably from before you replaced the drive, which is what you were thinking, but the error listing in this status report doesn't go away until you clear the error. I think that is the way it is intended to work in an effort to ensure that you see there was an error.

You should probably take a look at the other drive also, just for completeness.

That's is kind of what I was thinking. Basically, cyberjock just had a suggested schedule for smart tests and srubs that I followed to kind of fit into the best practcies.

Running a new long test now and will report back....

I thought it might just be that the error wasn't cleared from before the failure so hopefully that's the case, I just bought the new 4TB drives so another drive would be hard to explain to the the wife haha.

:) I know how that is. I have a similar pool arrangement to yours. I replaced 6 drives (one vdev) going from 2TB to 4TB, in the last part of 2017. My wife doesn't want me to buy any computer hardware now. She even suggested I should sell some.

You were the reason I went 6 x 6 if I remember correctly. Few weeks ago I was going to upgrade to 10 and it was recommended to me to go to 12 instead with a 6x6 config. I had the 6 2TB already and started from scratch on the 4s, so that's 6 4TB drives at once, then I had a drive failure on one of the 2s so that got replaced, fortunatly I'm building out one for my dad as well so I had a few drives ready to go, but got to replace his haha

Combine that with a truck work and completly tearing up our front yard for a redo of the walkway and flower bed, and just today order a portable 2TB drive for a photo trip I'm taking next week (dropped my last one) and I'm pretty much maxed out on the "Honey Can I get" credit card haha.

Thankfully all of the above was done cash so I only have to worry about her "honey do" list interest instead of the actual cash interest from a real credit card

I had 5 trees taken out of my yard because they were too close to the house and we have had roof damage from limbs falling. One took out the windshield of my car a couple years ago and other times thy have left dents. We finally decided the trees had to go but the tree company wrecked our yard. I will be working until next summer trying to get it back in any kind of shape. We had a continuous concrete curb around the flower bed in the front yard and they broke it in three places along with breaking four stepping stones. It is just too much and the tree company told us that the guy that we were working with took the money we paid and skipped town so the company never got paid.
