One or more devices has experienced an error resulting in data corruption

Donny Davis · Mar 18, 2019

So I woke up yesterday morning to this error.

Code:

The volume tank state is ONLINE: One or more devices has experienced an error resulting in data corruption. Applications may be affected.

It was a rpm package that had been rsyncd in from a mirror as I use my freenas for local mirror functions. Upon using the trusty googles, the unanimous consensus was to get a backup of my data immediately. Thankfully I have the gear to do so, and its in flight right now. I do have other backups of my most precious datas that run daily, so if this blows up its not a deal breaker or anything like that.

So getting to the question part, how do I get to the root of the issue. I am using ECC memory, and as soon as the backup is done I will run memtest to see if some ram has failed. Is there anything else I should be looking at, and what to do if its not the ram.

This system was built all new in Oct of 2018, it shouldn't be failing yet with one exception. The drives are recycled, so if they are crapping out its not a surprise... but how do I go about figuring out which on it is.

Thanks

S.M.A.R.T reports?

Donny Davis · Mar 18, 2019

Yea that is probably a good idea. I also have a couple drives with failed checksums. Not sure if that is relevant.
Is that the only thing I should be looking at? Is this just an indicator of a drive failure or are there other components in the system I also need to be looking at.

Thankfully ZFS tells me that data is bad, otherwise I would just go about my life acting like my data is all good when it isn't.

I'm trying to use this experience as a lesson in what not to do, or how to fix it.

That's what you call a clue. The error you gave us in the initial post indicated a disk error. Any disk error should be taken seriously and addressed atonce.

I am also curious what the output of the command zpool status is, because there must be multiple failed drives to have permanent date corruption.

Donny Davis · Mar 18, 2019

Thanks Chris :)

I planned to make some reasonable assumptions about the error, but its better to ask if I don't know definitively.

Now that is really weird... when I checked yesterday there was more than one drive with an error...

Chris Moore · Mar 18, 2019

It's possible for ZFS to correct some data errors from parity data. The underlying disks can still have errors.
Test the drives.

Yes, we want you to ask.

Donny Davis · Mar 18, 2019

Aside from S.M.A.R.T tests, is there anything else I should be doing?

Running the tests is the only 'active' thing unless you want to make a backup of your data. I have some questions that might help me come up with some ideas though.
Do you know what model number hard drive do you have? From the description,3TB Hitachi Enterprise drives pulled from an EMC Isilion x400, I am thinking they might be SAS drives, but I would love to know more.
I think we need to figure out why you got the error that caused data loss because that is certainly not something that we want to see more of.
Doing the SMART test is about trying to find out if there is a mechanical fault with one of the drives. We usually see some indicators in the results.
Also, what kind of SAS controller are you using?

What is the sub-version of the firmware on that? It should look something like: 20.00.07.00
You can get that from the terminal using sas2flash -list, it should look similar to this:

SAS Controller
Firmware Version : 20.00.04.00

We need to get that updated to the 07 sub-version. there were a lot of fixes for various problems between 04 and 07.
Yes, this could be part of the problem.

Looks like you are doing a short test every hour. That might be a little too often. I usually do a daily short test.
I don't see any indicator of a long test though, but it might have gone outside the list bound.
I would suggest changing the schedule for the short test to daily instead of hourly and have a long test on a weekly basis.

First thing, I think getting the firmware updated is the priority. After that, I think it would be a good idea to manually run a long test so we can see if it finds any drive defects.

I don't understand why its doing the short test every hour... What did I misconfigure?

From what is shown there, I don't see the problem.
How do you have this screen configured?

Donny Davis · Mar 18, 2019

They are configured to run every day of the week, and from how I thought it would run at 0600 every 5 days.. I must have something misconfigured, because I can surely see every disk is being smart tested every hour.

Donny Davis · Mar 18, 2019

I'm about halfway there on my backup - I have a nearly production Ceph cluster I am backing up to... and the data is of course moving uncompressed. So my 6ish TB of data needs to move 11TB over the wire... Gonna be a few more hours.

Thanks a bunch for the assistance with this @Chris Moore. I really appreciate it.

While the backup is running, I am going to tinker away with getting Openstack running on the latest release. I have been working at moving the driver to v2 of the FreeNAS API.

That schedule actually looks fine. Is it possible that you changed this setting through the API?
