Read Errors on System, FreeNas Mini XL

stoth · Jan 7, 2019

So I've got a hand built FreeNas with 8 Drives HDD (and 2 ssd for ZIL/Caching) and when it works it's great, but I think that either my mainboard is failing due to age/abuse (I recently had the main CPU heatsink fall off and had to reattach with new thermal paste). So now I'm getting timeouts to the drives after an extended copy session which seems to have made my drive array degraded. Overall I really like FreeNas as an OS and I would like to fix my current system but I've been through a lot recently with this machine and am almost at the end of my rope.

So if I upgrade to an Freenas Mini XL, what hardware can I take to it?
Will my current RAIDZ2 pool (8 x 4TB 3.5" drives) 'just work' if I put it into a new system?
Can I also put in the 2.5" SSD drives in for cache/zil?
What's upgrade-able on a Freenas Mini XL?

Is my current system worth saving if I might have fried it?

You mean to say that there is not something holding it other than the thermal compound?
Can you tell us what hardware you are using?

It would be a good idea (I think) to have some idea what condition your drives are in and you already say that the pool is degraded. Would you please share with us the output of zpool status which should look something like this:

No way to know without knowing what your current system is.
Please look here as it gives guidance on the kind of information you should share:

The drives, probably, we need to know more about what you are using.

Maybe, but we need to see what the health of the drives is.

stoth said:

It is possible, but you may not even need those. How are you using the system. What purpose is it serving?
Here is a video that shows the process for installing SSDs and memory:

Just the SSDs and RAM, and adding data drives.

Thanks, I'll get the hw data tonight when I'm back at home. If this sounds like a cry for help it is cause I've been fighting this system for a long time now and every little thing has been a battle.

When I said that the cpu cooler fell off, I mean it was attached properly when I put together the system, then probably through being moved around it fell off. Note that this system had been running for a few years before this happened. I noticed because the system became unstable after extended use and eventually I think the cooler became so loose that it started to overhead very quickly and throw temp warnings after only a few minutes of use.

Sorry to hear that. With good hardware, FreeNAS should be pretty problem free.
Do you know about how old the drives are?
The worry I have is that the drives might be failing due to age or prolonged exposure to heat.

Often, once a component overheats, it never works properly again. If it is a socketed CPU, it might be possible to replace it. If you can share more details, someone can help you get answers. If you decide that you just want to fully replace the old system, it is possible to build a system from parts for less than the cost of a Mini XL.

Thanks so much for helping me debug this, it's really appreciated.

So I restarted it to get data for the post and it resilvered the 2 disks which had errors, they both currently have CKSUM which is probably an issue with cabling. It seems to be ok now, though I haven't restarted and large transfers. When it declared the 2 disks bad I was in the middle of a multi-TB copy into the array. I pulled the smartctl for the bad drives.

Drives 0 and 3 have Checksum errors but their smartctl doesn't show anything. Drive 3 has previous smart errors, included below as well.

I agree that the CRC errors on ada4 are likely a cable. You might try reseating the connector on each end or replacing the cable entirely but that is just an annoyance and doesn't appear to be causing serious issues.
For drives ada0 and ada3, could you post the output of smatrctl using the -x option instead of the -a because I think the additional details might answer some questions.

Do you know when the system ran a scrub of the pool last?

stoth · Jan 8, 2019

I ran a scrub about 2 weeks ago I think, before the CPU fan fell off. Both these drives have over 1 year of run time.

You have not setup scheduled self-tests on your drives and no tests have been run.
Here is how you setup the schedule:
https://www.ixsystems.com/documentation/freenas/11/tasks.html#s-m-a-r-t-tests

I do a short test on my drives every day. It takes less than 6 minutes even on my 6TB drives, so just pick a time and do it. I have mine set for 6AM daily. I have a long test scheduled to start at 7 AM, so it runs while I am at work and it starts after the short test is done, and I run those once a week.

For the moment, because you have some issues and we are troubleshooting, I would say it is a good idea to do a long test on all your drives, and they can run all at the same time because it happens inside the drive. The command to kick that off from the command prompt is this:
smartctl -t long /dev/adaX -- just replace X with the number of the drive you want to test.
It should give you an estimate of how long the test will take. This will check the drive for mechanical defects.

Do you have spare drives? You might want to get a couple. Usually, when this kind of thing happens, it is because there is a problem with the drive.

Has the system been running mostly stable?

Thanks for the tip, I thought that I had the smart long test scheduled, I tried to reschedule it in the GUI. I started the long test but it's going to take till tomorrow morning for most of the drives, will update then.

I do have spare drives, so will sub in if there are issues found.

This system has always had issues under heavy load. As long as I kept the load lighter it seemed more stable but under long copies it seems to have issues. This is just my home server so I don't have the best logs. I should really invest in a logging system with a durable store :)

It may have temperature issues. If you can give us some details on exactly what the hardware is, it might help us figure out what the problem might be.
Here is a link to a configuration guide that might help you get your system adjusted to work better:

Here is a link to some scripts that will help you keep track of your system help:

So I finished the full long SMART scan on my drives and no errors on any of them. They all have a section that looks like

Code:

SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error
# 1  Extended offline    Completed without error       00%       959         -

Which to me seems to mean that there are no issues with my drives which is good! I'll try doing a long copy again and see if I can replicate the errors.

stoth · Jan 11, 2019

So after all this debugging, it's been stable for the last 3 days with no issues. The Resilvering went fine and I even managed to just use it like normal, making a backup of some files just incase.

Thanks for all your help with the debugging!
