99% of files gone

[DatScreamer]

Hi. This is my first post. I have configured a FreeNas server and now transferred all of my data for the past year onto it. This is over 2 TB in size. 5 minutes later I look for the data and it is gone. There is one folder that I created but it only contains 20 GB of files. The storage area on my Nas says there are 50 GB uses though. Where are all my files? I have checked hidden files option on windows explorer.

I am freaking out here. All my data that I worked so hard for is missing. And it will ruin my life if I cannot get it back. So many client's data was on there...

Help please ASAP

Just to get a baseline of options, is there a backup of the data available?

No there is not. I had just set it up yesterday.

Is the source of the data (what you copied to FreeNAS from) no longer available? If it was just copied yesterday, I'd think that would make the existence of the source data more likely. Was the source drive repurposed or something?

My data was on my dad's Synology NAS, he wanted it off his so I repourposed a rally old lenovo computer and turned it into my server/nas. I cut/pasted the data from the NAS to my NAS.


BTW I have the CPU that is in your server in my PC.

OK, it's unfortunate that the data is no longer available on a backup/source. That would have been an easy fix.

This is where I will need to let others chime if they are able. I'm not well versed on data recovery from simpler file systems nevertheless ZFS, and if we're looking at a true data recovery scenario here it's simply out of my league. Sorry.

Post a debug file. Click "system" -> "advanced" -> "save debug"

And then what? I clicked it and nothing happened I don't think?

It takes a while for the process to complete and generate a debug file. Wait for a while.

After it is done what will it do?

 

[DatScreamer]

Here is the debug file.

My gut feel is that if you don't have the data somewhere else you really are up the creek without a paddle :(

And I'm not sure what help you'll find here, as your hardware doesn't meet the minimum specification in so many different ways.

Might have been a good idea to introduce yourself and find out a little more about FreeNAS before taking such a drastic leap, especially one which involved deleting the source data before you'd fully checked that it had copied across successfully.

Sorry

My nas has a core duo 2.13 ghz, 4 gb ram. How does this not meet requirments

FreeNAS requires 8GB RAM otherwise bad things can happen. I'm looking through your debug now. I'll let you know if I see anything.

Your server shows that you are have about 38.1G of data on your NAS and no snapshot tasks configured. Does this sound correct? You have not destroyed a ZFS dataset and so my guess is that either (1) your data is there, (2) your data never transferred to the server, or (3) you deleted the data from your server.

In the webgui, click on "Shell" and enter the command "ls -l /mnt/screamdisk". Do you see your data?

I got:

[root@screamserver ~]# ls -1 /mnt/screamdisk
ScreamDisk
screamdisk
[root@screamserver ~]# ls -1/mnt/screamdisk
ls: illegal option -- /

I did not delete a dataset? what is a dataset?

You're really not doing yourself any favors here. Read the documentation: http://doc.freenas.org/9.3/freenas.html Read the various stickies in the forums. They will answer what a dataset is.

Type the following command and paste the output here

Code:

 ls -l /mnt/screamdisk/screamdisk

there are spaces between "ls" and "-l". Additionally, the shell is case-sensitive. make sure to type it exactly as above.

Then type the following command and also past the output here

Code:

ls -l /mnt/screamdisk/ScreamDisk

You should know.. you created one.

At this point, for the safety of your data, you should take a snapshot of the whole pool, recursively.

It looks like your data is there, I just think you don't know how to access it.
