Help locating corrupted file

[matt11601]

Hello,

I've been in the middle of upgrading hardware and got sidetracked with a warning for an unhealthy pool. This is a single disk pool that was replaced today with a Samsung SSD. The old Toshiba drive had numerous errors occur daily such as

* Device: /dev/ada0, 1240 Currently unreadable (pending) sectors.
* Device: /dev/ada0, 25 Offline uncorrectable sectors.
* Device: /dev/ada0, ATA error count increased from 70 to 75.

I used the replace function and resilvering went well. I shutdown the machine, removed the old Toshiba disk, physically moved the Samsung SSD from my PERC card to SATA (old location of Toshiba), then rebooted. The pool was still marked as unhealthy so I did some investigating.

Put of zpool status -v

From the zpool status -v output, the corrupted file is "Torrents/iocage/jails/MediaDownloader/root@ioc_update_12.2-RELEASE-p15_2023-04-07_14-54-59:/media/downloads/tv/The.Diplomat.S01E04.1080p.AHDTV.x264-DARKFLiX[rarbg]/The.Diplomat.S01E04.1080p.AHDTV.x264-DARKFLiX.mkv.part" I have no idea how to locate this file. In the shell, I can get to "Torrents/iocage/jails/MediaDownloader/" but am stuck after that.

Does anyone have any advice on how to fix this? My assumption is deleting this file and scrubbing will fix the errors, but that may be incorrect on my part.

Hardware configuration is in the signature.

Thanks for any help you can offer.

Any ZFS path, (not OS path), with a "@" is a snapshot. I am not sure WHY your snapshot has such a long, extended name. It is possibly not a snapshot. If you could supply the output of the following command in code tags, we can verify.

zfs list -t all -r Torrents


The only way to get rid of file(s) in snapshot(s), is to delete the entire snapshot;

zfs destroy Torrents/iocage/jails/MediaDownloader/root@ioc_update_12.2-RELEASE-p15_2023-04-07_14-54-59:/media/downloads/tv/The.Diplomat.S01E04.1080p.AHDTV.x264-DARKFLiX[rarbg]/The.Diplomat.S01E04.1080p.AHDTV.x264-DARKFLiX.mkv.part

This will also delete any held files in the snapshot that no longer exist in the parent dataset. But may be good files.

Note that it is possible that the broken file is also in the parent dataset. So deleting the snapshot might just be the first step.

 

[sretalla]

That's not the name of the snapshot... it's the snapshot and the path within it, separated by a colon...

zfs destroy Torrents/iocage/jails/MediaDownloader/root@ioc_update_12.2-RELEASE-p15_2023-04-07_14-54-59

should suffice.

Ahh, that makes sense.

 

[matt11601]

Thank you @Arwen and @sretalla for your help.

I deleted the snapshot, scrubbed the pool (from GUI), and rebooted. I re-ran

Code:

vpool status -v

but still see the error and the pool is still marked as unhealthy. Is there anything more I should do?

 

[Arwen]

Can you list the actual output of zpool status -v Torrents ?

It is possible you need to run zpool clear Torrents then re-run scrub.

 

[matt11601]

Can you list the actual output of zpool status -v Torrents ?

Yep, here you go

[Arwen]

Looks like you have yet another corrupt file. But, I would clear the errors and re-run the scrub. If the error is still there, then get rid of that snapshot too. Then repeat clearing and scrubbing.

Not sure why it did not report this problem sooner. But, it is possible your single disk pool is starting to fail. Thus, more errors could be in store for you.

Try posting the output of smartctl -a /dev/ada0 against that disk. Perhaps we can see if the disk is truly failing.

 

[sretalla]

That's in a different snapshot...
Torrents/iocage/jails/MediaDownloader/root@ioc_update_13.0-RELEASE-p13_2023-04-07_16-21-51

I think it's time to start worrying about why you're getting corruption in multiple locations in your pool...

That's a single-disk pool, is your disk doing OK? smartctl -a /dev/daX (replace daX with the actual disk identifier from that pool)

 

[matt11601]

The disk is brand new Samsung SSD so I would hope it's not faulty, but certainly possible. I replaced a dying Toshiba disk. Is it fair to assume that the corrupted data got resilvered when I replaced the Toshiba disk with this Samsung SSD?

Here's the output of that command

[sretalla]

so that drive hasn't logged a self test.

You might want to launch one:
smartctl -t long /dev/ada3

Then run with -a after some hours to check the results.

 

[WI_Hedgehog]

A faulty cable or connection (data or power or both) can also cause issues. We generally aren't as careful with cables as we should be, expect they were manufactured perfectly and withstand being treated poorly.

Dirty Power can be another issue. I just had a Chinese fan dirty up the power line so much the PSU shut down if the fan was the only thing in the line (a Noctua didn't have that issue). I paid less and got less, it just wasn't evident in normal use though showed up under the rigorous testing I now do for new systems.

@WI_Hedgehog Your comment was very helpful and just reminded me of something. I was going through my list of upgrades and realized I haven't upgraded my PSU yet. I still have the stock PSU which is 290W which, embarrassingly, I thought I upgraded prior to installing the new drives.

Based on this, I am going to upgrade the PSU ASAP because I suspect interpreting all these tests will be confusing until this major issue is addressed.

@matt11601 : Awesome.

If it helps, I bought a UNI-T UT210e Mini DC Clamp Meter to see current draw, and should probably also buy a scope to watch for dirty power--that can happen when drawing over 85% PSU rated capacity as the torroidal filters saturate in some mid-grade and lower power supplies. In any PSU old capacitors dry out and lose filter capacity....
