Question On my freenas, pool is now degraded. RMA new drive?

[Shmee]

So I have my Freenas setup with 3 4TB WD Red Pros on an X58 board in RAIDZ. I notice now that the status is degraded, and that ada0 is faulted. I assume I should RMA this drive? Even though it is pretty new, since it is faulted? Let me know if you need any more information about this setup.

It sounds like you should. More information about the fault couldn't hurt. But, if the array is degraded then you need to get a replacement in there to rebuild asap or risk losing the array if another drive fails. Also, note the failedd drives serial number from the GUI, and get the right drive by verifying the serial number on the drive itself.

IMO, you should keep a few spares of the same make and model on hand. Focus on the array first, then the RMA as those can take sometime.

Ya, makes sense. I am not sure what attibutes failed on the drive, but I went ahead and shutdown the NAS, and ordered 2 new drives and a hotswap bay.

It means SMART check failed the drive.
As Cheeze stats replace drive STAT.
I would buy a Drive and not just sit and wait on a RMA, or at the least, get a refurbished 4TB drive to rebuild the array, as you can rebuild it again once u get the RMA back, but definitely do not leave the pool degraded without a redundant backup of some sort.

Once you pull the drive out, i would run a smart on it, and see the values to determine where it failed.

Also sometimes it may not be the drive but a lose connector.
Double verify its not a physical issue, because red pro's just dying like that is very rare.

If a drive fails, I always pull it out of the array to test it with that Vendor's tool on a separate machine. Because that will give you the solid evidence you need to get the disk RMA'd anyways. Then you'll know for sure it's bad.

Well, here's an update. After installing the hot swap bays and re cabling, and putting the drives in the hot swap bays, the pool is online healthy again. I think one of the cables was damaged, I found one in there that had a small part broken on it, so I replaced it.

lol... i called it..
I have had that happen to me before.

I was cleaning the inside of my NAS and accidentally jar'd one of the cables.
This is why i always use a SAS and SAS expander as it makes my life a lot easier and prevents things like this.

@Shmee good find!
