Two Checksum errors on each and every drive after a resilver and replace. What to do ?

2 Checksum errors on all of the drives after a resilver and replace >
My SMB shares are working, but on the dashboard, Pool Status shows 'degraded', yet all drives show 'Online'

errors: Permanent errors have been detected in the following files: V4TBx8R2/.system/rrd-d968e280827d4008b5065e3ef738a9cd:<0x3eb>

Move your system dataset to your boot pool and back again (that should deal with the corrupt file).

Then run a zpool clear on that pool

Thanks so much for taking the time to reply. I have looked, but cannot seem to find a procedural to do that move. Can you point me to one, or explain to me in more detail ?

 

[sretalla]

System Settings | Advanced.

In the box labeled Storage | Configure.

Pick the boot pool instead of the pool shown.

Save, then give it a little time (optionally a reboot), then back to the same place and set it back (after doing zpool clear).

 

[10Gauge]

Found it. Seems it had been moved to Settings > Advanced. So all I do is toggle it to boot and then back ?

 

[sretalla]

See my post above where I already mentioned what to do.

 

[10Gauge]

Yes, Thanks, I posted just before your reply. Can I assume that you meant System Dataset | Configure ?

You may need to reboot to free that up then.

Thanks for the tip, but sadly, still showing Pool Status as unhealthy

still showing Pool Status as unhealthy

Did you do the zpool clear?

can you share zpool status?

 

[10Gauge]

Yes, I did the clear. Just repeated it. No Joy.
I have full SMB access and it appears to be working properly. Just shows the error on the dashboard. FWIW.

The pool can still be used, but some features are unavailable.

the pool may no longer be accessible by software that does not support
the features. See zpool-features(7) for details.

I would highlight this as the answer to the pool's degraded state.

zpool status -v

to find out which file is impacted and think about how to handle that.

 

[10Gauge]

You have almost helped me to a solution, but how do I resolve it ?
The file seems innocuous and deletable, but I am stumped as to how to clear the error on the Truenas Dashboard.
Do I simply rm the offending file ?

 

[sretalla]

You can try that, but it's part of the system dataset, so you may need to move that to another pool (boot pool if that's all you have) and then back again.
