Pool Unhealth ??

[StarTrek133]

Hi Everyone,

Need some advice .. I Noticed today that one of my pool's is unhealthly but cant seem to figure out why .. everything from my little understanding of TrueNas looks fine .. So could use some help ..

Thanks ..

You need to click the cogwheel to the right of the pool name and select "status" to see what's going on.

It's likely you have some read/write or checksum errors on one or more disks.

Yeah I thought it might be something like that .. but when I click its all zero's .. So I am confused ..

 

[Samuel Tai]

This is likely due to SMART errors on drives. Run a SMART long test on all your pool disks.

Thanks Samuel .. I get up the following and Hope I did it right .. So will just have to wait and see ..

 

[Samuel Tai]

No need to wait for the scheduled tests. From Shell, run smartctl -t long /dev/ada0, and repeat for the other drives in your pool. Run smartctl -a /dev/ada0 | more periodically to see when the test finishes, and again after test completion to see the results.

Thanks Samuel .. I think I have all the drives being tested now .. but when I run your command to see if the test finishes I am not sure what I am looking at it .. So I have not idea .. I would assume for a 6tb drive it would take a while .. wish there was a progress bar or something ..

 

[Samuel Tai]

Near the top, there will be a line that says: Self-test execution status. This will say either a test is in progress or is completed.

Hey Samuel .. sorry to say I don't see that I must be missing it .. here is the out screen shots .. hope they help ..

 

[Samuel Tai]

Look at screenshot 232912, about 4 lines down. There's a header titled Self-test execution status. In your case, the test completed, as you can see in screenshot 232949.

Thanks Samuel ..

I get it now .. so if it completed with no errors then I wonder why the pool is unhealth ....

Thoughts ? ideas ?

All the rest of the drives say the same thing that it ran but with no errors or issues ..

 

[Samuel Tai]

What does zpool status Computer\ Core say? Note, the error message may be a function of the pool name having a space in it.

 

[StarTrek133]

From what I can tell says everything is fine ..

 

[Samuel Tai]

Please rerun with zpool status -v Computer\ Core. The error message indicates you may have damaged metadata.

 

[StarTrek133]

This is what came back ..

So I have bad files I would assume ..

 

[Samuel Tai]

Yes, try deleting those files and running a scrub. This should restore your pool to health. Then restore those files from backup, and run another scrub.

 

[StarTrek133]

Thanks will get that done .. how do I check to see if the scrub is running ? I clicked the button and hit confirm and now I am not sure ..

 

[Samuel Tai]

Just run zpool status -v Computer\ Core, and you'll see the scrub progress. If you kicked off the scrub in the GUI, you can watch the progress bar under the Task Manager icon in the upper right (looks like a clipboard).

 

[StarTrek133]

Aahhh thanks Samuel .. I was wondering if TrueNas has a task manager .. I found it .. its at 40% currently .. So hurry up and wait ..

 

[StarTrek133]

Hey Samuel .. Thanks again for the help .. I let it run over night and its back to being Healthy again .. So let's hope I am good .. I also found this and set it up .. I hope ..

Still new to all this ..
