View Disks Empty

[HDNewbie1028]

Hi, I am still relatively new to Freenas. I built my box 4 years ago. I am running Freenas 9.2.1.8 64x. I have a RAIDz2-0 setup. 4 4.0TB WD disks. 2 are WD Green. 2 are WD Red.

Last week I had a power outage at my home that lasted for a couple hours. The FreeNAS is on battery backup, and I have a whole house surge protector through my utilities company. However, this weekend I was moving items from my desktop internal HDD to my NAS in anticipation of a new desktop build I am going to be working on, when I noticed my NAS was powered down. I remembered the power outage. I turned the NAS back on. Everything came back on and there were no red alerts. Here’s the kicker - I used to be able to view all 4 disks, but now none are showing up in the Web GUI. Also, although there are no alerts and it says the one volume is healthy, it says I only have 4 TB of storage, not 8.

I also have a message that says "Device: /dev/ada3, 3 Currently unreadable (pending) sectors" and I don't know what that is about.

So, I think I have a few issues here. The first is why aren’t my drives showing up, 2nd, why does it say I only have 4 TB of usable space instead of 8 TB, and lastly, do I have a HDD blowing up? Or, did the rest blow up and I only have 1 working drive?

Do a zpool status -v from the command line and post the results in code tags.
