SOLVED HELP! - Can't boot after Power loss

[Michael Guerriero]

I was changing some cables near my FreeNas when I accidently knocked the power cable loose and caused an abrupt power loss/shutdown! I nearly shat my pants because I've read how temperamental things can be with power loss (Which is why I have a UPS, but that didnt help me here!). Anyway, I tried rebooting and I'm getting the below. Sorry for the picture. Any ideas? I tried booting to a single user, but it can't locate the pool. I don't know how to decipher what is wrong.

I'm running a 6 disk RaidZ2 off a Sandisk USB stick. It's been running great for a little over a year. Can anyone help or point me in the right direction? Is my pool lost?

Sorry I should also mention, more about the stats of my setup.

ASRock Z77 Motherboard
Core i3 3.3Ghz
16GB Ram
6 - WD Red 2 TB Disks
Intel NIC
4GB Sandisk Cruzer USB 2.0 Stick

I'd say your FreeNAS install is corrupt. Reinstall FreeNAS on your USB stick and reupload your config file.

Thanks for the reply Cyberjock! So I'm a noob and I didn't save my config file. From quickly reading around, it sounds like that it would be lost at this point, correct? Or can I recover it from the usb stick?

If not, is my best bet to re-install FreeNas on another USB stick fresh and try to auto-import the pool?

kernel panic or somesort.
i had done this before, i turned off my mains power without realising that i had the nas and my desktop on, the file system was clean and i was able to continue, im not sure if i had to change usb sticks but i did anyway

You have a few options that I can think of:

1. Try to bootup FreeNAS from your USB stick and run a fsck. You'll have to do it as single user and I don't know how to do that with FreeNAS. So I can't help you with this more than that. Not sure this will help as it says the file system is clean.
2. Try to do a FreeNAS "upgrade" by upgrading to the same version you are already on. It should pull your config file to the "upgrade" partition and FreeNAS might just boot up and be fine.
3. You can install to a fresh USB stick and attempt to mount the old USB stick to get your config file
4. Kiss the old config goodbye, install FreeNAS on any USB stick you want then import the pool and redo the setup in the GUI.

Looks like my USB stick was corrupted. Ended up going with option 4. Fully recovered the pool successfully, just need redo the settings now, no biggie. Thanks for your help guys!
