Volume disappeared after running the "reset to factory defaults" in CLI

[daf]

Dear all, I have a freenas system with 2 zpools, 1 consists of 8 drives zraid2 labeled "Tank" and a 3 drive zraid1 labeled "Test"
After running into some networking trouble I decided to invoke the "reset to factory defaults"

After rebooting I was able to import "Tank" from the GUI, but no signs of the volume "Test"

I read quite some posts on the forum but I cannot find a way to relocate Test en import it again..

All HDD drives are available...

zpool history just gives me info about the current pools

Here's some info:
I hope I can invoke a forced imput by pointing to one of the drives that is part of "Test" but not really sure how..

I simply cannot find anything related to "Test" anymore..

Any hints on how to go from here?

Thanks in advance,

Import the pool.

http://doc.freenas.org/11/storage.html#import-volume

 

[daf]

Thanks for your answer, but importing the pool is what I'm trying to establish here...
In Storage → Volumes → Import Volume, the only volume showing up in the drop down box was "Tank" (no sign of "Test")
Running

Code:

zpool import

from the shell doens't do anything.. The disks however are available when you look at the output from camcontrol devlist

gpart show output? Looks like there is no pool created on those other disks.

I'm really sure there used to be a pool on these 4TB drives.. It also contained quite some data..

I'm thinking it could be that this particular pool was created wth zfs on linux and not with freenas at the time I was running a dual boot with a linux system.. Could that be the reason?

Let's try to install linux once more and see if I can import the pool from there..

 

[daf]

No sign of the pool in ZOL as well... Could it be "reset to factory defaults" accidently destroyed one of the pools?
zpool import -D however doesn't show signs of a destroyed pool as well..

You would have to create a test scenario to try it out. I highly doubt it got deleted by freenas. Much more likely it got deleted by a human. zpool history might give some insight into what commands have been executed.

Hi there, once again thanks for your reply. I'm absolutely sure there was a volume called "Test" containing my data at the moment I invoked the "Reset to factory default" command and that the volume mysteriously disappeared.
zpool histroy just gives me info about the 2 volumes (root and Tank) that are actually available..

My current priority is getting my data back.. after that I will try some test to see if I can reproduce this..

Anyone that has some advice what I can try to get my data back??

Kind regards,

Daf

 

[gpsguy]

Please provide detailed hardware information, as well as FreeNAS version.

Do you have a hardware RAID controller in your server?

 

[daf]

Hi there, my freenas version is: FreeNAS-11.0-RELEASE (a2dc21583)
My hardware config is:

• main board: Supermicro Flex-ATX X10SDV-4C-7TP4F D-1518; this has onboard a Broadcom 2116 SW controller. http://www.supermicro.com/products/motherboard/Xeon/D/X10SDV-4C-7TP4F.cfm

• chassis:

SuperChassis 846BE16-R920B https://www.supermicro.nl/products/chassis/4U/846/SC846BE16-R920B

There is indeed a raid controller on the mainboard, but I'm not using it..

 

[joeschmuck]

My initial thought is the pool was accidentally destroyed by the operator by accident but you are insisting that it was actively there before performing a Factory Reset. I certainly hope this isn't the case but we have to take you at your word.

Let me ask you a few questions...
You were already asked for the output of zpool history so please provide it. This will speak volumes.

If you want to try something then my unorthodox methods would be as follows (after you provide the data previously requested):
1) Shut down the machine.
2) Unplug your drive chassis.
3) Move the three drives for pool Test to the SATA ports marked SATA 1, 2, 3. I want to use the SoC controller directly.
4) Boot up your machine and try to import your pool. You will likely have errors about the pool "Tank" not being present, that is okay.
5) If your pool "Test" imports then report it here and count your blessings.

I don't want to go any further, lets see how this goes.

I will try your suggestion later this week although I'm a bit hesitant since I don't want to lose the data on "Tank"; I'm currently in the process of setting up a backup server for this particular volume, so maybe I'll wait with trying your suggestion untill I have Tank backed up..

In the zpool history output I don't see anything fiddly..
