Accidentally removed a drive

[hendry]

Hi, I accidentally removed a drive in my raid array (I am not sure what the correct terminology is.). Thinking it was an empty bay...

I plugged in straight back in after I noticed the error. I can't see anything untoward https://s.natalian.org/2019-03-06/status.txt

So everything is OK? I didn't think my drives were hot pluggable for some reason.

Probably. What does the pool status page show?

 

[Jailer]

I'd run a scrub just to be sure.

Can't see a way of starting a scrub from the UI https://s.natalian.org/2019-03-07/1551908438_2560x1440.png

Also from the UI, how can I tell how the previous scrubs went?

Please don't point to externally-hosted material unnecessarily. But that suggests that the disk wasn't out for long enough for FreeNAS to notice, so again, in all likelihood, you're just fine. Though as @Jailer says, a scrub would be a good idea. I'm pretty sure you can start them on demand from the Storage -> Pools page (hamburger menu next to the pool in question), but I'm away from home right now and can't get into the FreeNAS UI.

That is correct, it's in the section I linked to from the manual.

If you need a manual, perhaps the UI navigation disparity between `/ui/tasks/scrub` & `/ui/storage/pools` could be... addressed instead?

@hendry - Pointing to externally hosted material leaves open the possibility that that material may become unavailable at some point in the future, rendering this thread incomplete or otherwise useless to future readers. Use the "code" markup tag for output like "zpool status". It formats the spacing correctly for readability, and the thread will be preserved intact for the search engine, giving back to the community.

The forum seems to allow external links, so I will use them. I don't have time to jump hoops.

It allows external links because that's sometimes appropriate. Copy -> Open Code Tag -> Paste -> Close Code Tag, is hardly jumping thru a hoop. It should be faster than uploading a text file to your web server.

Remember, members of the community are taking time out of their days and jumping through hoops to help you. We would really appreciate it if you would be willing to upload the content here so others can benefit.

There is no hoop involved in using code tags like this [CODE] with your text inside [/CODE].
Then your output can be in the forum like this:

If your time is that much more valuable than everyone else's, I guess you can figure things out for yourself. *plonk*
