Degraded Volume

[reedjasonf]

Hi...

I have a system with FreeNAS-8.3.1-RELEASE-x64 (r13452.

I had four 1 TB WD green drives installed and set up in a Raid Z1 but those drives eventually started failing and the pool was getting full anyway so my plan was to slowly replace them with 2TB WD red drives to both get rid of the failing drives and increase storage space.

I had already replaced one of the green's with a 1TB Red about 6 months ago with no problem and I actually saw performance get much better.

Then I recently replaced another one of the green's with a 2TB red making sure that autoexpand was turned on. After resilvering completed I noticed that on my 'View Volumes' page it says "Degraded" under the status column for the volume and all the zfs datasets under it. However, when I look at the Volume status page it says all drives are online and FreeNAS says the ZFS pool is healthy. Why is my volume in a degraded state?

What does "zpool status" say?

What does "zpool status" say?

All it says is resilvering completed without errors and all checksums are all zero.

He wants you to post the actual output. He doesn't want you to interpret what it says. ;)

Can you post the output of the smartctl for one of your WD Reds please? Just want to check out something. The command is smartctl -a -q noserial /dev/XXX.

Thanks. :)

You honestly can't fill in the blanks? :-/

Btw, I was on my phone's browser or otherwise I would have posted it.

Here it is: Idk how to post the whole thing since it overflows my screen:

Also, another thing I noticed was the amount of available space I have has not increased. I made sure autoexpand was on before I installed the two 2TB drives. Do all the drives need to be the same capacity to be in a ZRaid? Right now I have two 2TB drives and two 1TB drives until about 6 months from now when I'll replace the other 1TB drives with 2TB drives.

Your pool will only use the lowest capacity drive to limit the pool size. Replace the 1TB drives with 2TB drives or larger and the pool will expand to use the 2TB drives. Of course do not replace them at the same time. Ensure you read the users guide as this information is there.

Also when someone asks for the output, we never assume anything except the person on the other end knows nothing at all. Don't take this the wrong way, it's a good thing. If I were to assume you knew something, well what level of knowledge should I assume. You can't post all of the smartctl information so you don't know how to scroll back the screen which is a very basic user function. You could also have just piped it to a file and posted that file but do you know what piping is? If I treat all people like they know nothing at all then when I'm giving advice, we will be on the same page. Or that is the goal. When it comes to your data would you want us to assume that the all important zpool status is exactly what you say it is or that there isn't some minor piece of data which you may deem unimportant that may have kept us from accidentally destroying your pool? Passing along all the requested data is the best way we can help.

So, how are you running the smartctl command, are you using the Web GUI Shell? If so in the bottom left corner, select a larger screen size if you can. Next enter your smartctl command. If it scrolls off the screen then type 'smartctl -a -q noserial /dev/XXX | more' and this will split it up into pages. Press the space bar to allow scrolling to the next page. Copy and paste each screen to make a complete list. There are other ways to do it but that can be a bit more involved getting things setup in the first place.

Again, did you miss the part where I was responding on my phone?

it's a brand new drive so nothing interesting here.

The problem seems to have resolved itself. I haven't restarted the server other than the one time after resilvering but now it's stating that the volume is healthy on the GUI.

1. You should have just waited so you could post the whole thing from a computer.
2. We've had brand new drives that were full of "interesting"parameters. Not to mention hard drives have a very high mortality rate for their first few months of operation. So assuming a brandnew hard drive has nothing interesting is a horrible assumption to make.
3. Glad the server resolved its problem. :)
