Alert: “Pool Testing is offline.” Huh?

Why?

It also says, “Not running scrub.”

You should post your complete details on your TrueNAS system. You have two, recent posts with problems and they may be related. What version of Scale are you on? Try to provide as much info as possible as that is all we have to go off for figuring out the problems.

Looks like you have very possible corruption. You know what to do, provide all the details for a pool problem, zpool status -v and all that fun stuff.

And yes, @SmallBarky is correct, you need to post more than just an error message, too many variables at play here.

@SmallBarky, @joeschmuck: That’s exactly it, I don’t know, what to look at. zpool status -v is a great start. I appreciate the hint!

The system is an N100 system with 32 GB of RAM. It has two 16-TB drives joined in a mirror configuration.

Here’s the output:

root@truenasmini[/home/truenas_admin]# zpool status -v

Nothing glaring enough for me to have a clue.

Did you have a pool called “Testing” at one point? I don’t see that in your list of pools here.

Check in the UI under “Storage”, do you see a pool called “Testing” listed there as offline?

I see how you read that. Clever.

Yup!

Let me see, how to get rid of that.

Got rid of it.
