After removing jail, all files missing but space is still allocated

[Xytek]

So after spending hours of moving and copying all my media files to new 4TB drive, I started to play with DLNA plugin. I was troubleshooting why i couldn't see a different directory under my main media folder when i decieded to just remove it and start again. Apparently i did something bad (tm). I freaked and reloaded a previous config to see if that would help.. it didn't. So here i am.
Looking through the forums, others have had similar issues with missing files. Here is some output:

Code:

Thanks for any help in trying to recover my files. Spent 4 years collecting.. don't really want to loose it all.

 

[dlavigne]

Does running ls through /mnt/diskad0/media and its subdirectories still show the files?

 

[Xytek]

No it doesn't. It shows the subdirectory (Media_Stor) of where i had 2 directories (named "Movies" and "TVSHOWS", both of which are gone)

Code:

*sigh* ok im coming to the conclusion that my data is gone. Some how the "pointers" to where the data is on the disk is gone, or corrupted, and with my limited knowledge of how this FS works, i don't think i can recover from it.

 

[Xytek]

So, im wondering if i deleted a dataset, would that cause my problem? where the space is still allocated, but no "reference" point pointing to where the data is?

 

[warri]

I think if you delete a dataset, the data should be gone. If you used snapshots for this particular dataset, they might still occupy the free space. I'm just not sure if you actually can delete a dataset when there are still snapshots of it?

 

[Xytek]

No, i was still in the process of moving files over and setting stuff up when this happened. I had been running Freenas for over a week with a smaller drive getting familiar with the setup. Yeah i dont think i deleted a dataset, infact i dont remember even creating one. I was just throwing it out there.

 

[cyberjock]

Hey, for 5-digits some data recovery professionals might be able to help. LOL.

So how much is your data worth? LOL

 

[Xytek]

now where near even a fraction of that
worth a shot at figuring it out anyways

 

[Dusan]

What is the output of df -h

 

[Xytek]

I gave up trying to figure it out and just wiped the disk. Thanks for the response.
