Formatted NAS from windows

[olafbeserka]

TrueNAS-12.0-U7

Let me preface by saying I am not expert, just an enthusiast. If I use the wrong terminology I'm sorry.

I have a HP N54L with 4 drives. The 4 drives are split into 2 raid 1 pools. This is shared via SMB to my Win10 desktop. My main drive holds all of my family photos. The other week I went to format my daughters microsd for her tablet. The microsd was used for a pi or nintendo switch, so it didnt show up in File Manager. I went to Disk Management, deleted the volumes and then formatted. Turns out I deleted one of my shared drives from my NAS.

I didnt realize until a week later since I never use that drive except to backup photos. So now when I see the drive in File Manager nothing shows in the directory. But it shows the drive is 1/4 used. You can see here https://i.postimg.cc/2jKz720K/dummy.jpg

Is there any possibility to recover my data?

 

[Patrick M. Hausen]

Possibly. You definitely cannot format a NAS drive in windows. At least not via SMB. So let's start with some commands you need to enter on the command line while logged in to your NAS via ssh. Then please post the output here.

First three:

Code:

zpool status
zfs list
testparm -s

There's at least the testparm output missing and probably some of the zfs list, too. Please do not use the web console - it's broken. Log in via SSH. Then enclose the copied output in code tags. Thanks.

There's at least the testparm output missing and probably some of the zfs list, too. Please do not use the web console - it's broken. Log in via SSH. Then enclose the copied output in code tags. Thanks.

hopefully this is complete this time.

So you have two SMB shares in two different pools that to me look like this:

share name	NAS path	capacity used
nas10	/mnt/freenas10tb/nas10	2.70T
fn4tb	/mnt/fn2/fn4tb	1.32T

If you do something like this in the shell:

Code:

cd /mnt/freenas10tb/nas10
ls -lR
cd /mnt/fn2/fn4tb
ls -lR

you will probably find that all your data is still there. Is that the case? That's what I wanted to assess first.

Why your Windows system presents the volume in this weird way, I don't know. Others with a better knowledge of Windows and Samba will have to step in here.

so nas10 is the one that is messed up. When i ran the command for that specific volume, it DOES show my files there! It hasnt finished loading everything yet, but so far I do recognize the directories and files. Which makes me very happy, but also still need to figure out how to access. It. Thank you so much for the help so far!

I had help on another forum. Basically since its impossible for windows to delete/format the truenas mapped drives all the data was still there. I just needed to remap the drive and everything showed up.
