Help with GUI Warnings (Storage Topology Metadata VDEVs)

[DontWorryAboutIt]

I had (2) SSDs in a mirror for Metadata. I was trying to make a 3-way mirror and clicked extended on the vdev and added a third SSD. After that, on the storage page it shows 2 warnings. Where do I look to review these warnings? I wasn't able to find anything in the GUI that lets me see what they are.
TrueNAS-SCALE-22.12.1

Thanks

You might be able to get more info on command line. Try with "zpool status" and if you need help deciphering the output, then paste it here in code tags.

Thanks so much for the reply. zpool status shows no errors and nothing out of the ordinary. Just want to make sure the warning isn't anything serious.

Also can you confirm that extending a 2-way mirror creates a 3-way mirror? I want the metadata vdev to have the same redundancy as my raidz2 data vdev.

The output of zpool status should show you if you have a 3-way mirror for your Metadata vDev. If in doubt, post the output here in code tags, and we can confirm it for you.

Much appreciated. Output of zpool status below.

That's certainly a 3-way mirror.
