Just lost over 1Tb of media files

I have spent a few days transferring media files to specific datasets in TrueNAS 25.10.1 - Goldeye, and just a short while ago today, most of the media files have just disappeared .The weired thing is that they seemed to have gone in alphabetically order from A down to P. The files from P on, are still there!!

Any chance you had setup automated snapshots so you can restore to previous state?

Also how are you confirming that they are gone? Are you checking off of the TrueNAS server itself or are you using SMB?

No unfortunately I didn’t have automated backups but I will from now on. The thing is, my data has been safe on freeNAS/TrueNAS for over 10 years, and it just happens now!

Yes I am using smb so I can share them on other devices

Have you tried exploring with CLI that the files are actually gone? Just to double check it isn’t some bizarre SMB issue? Or is the “total space used” actually missing 1TB compared to what it was before?

How can I do it with CLI, whatever that is.

No, there was over 4Tb of free space

CLI = command line interface

Congratz, your two new favourite commands are going to be cd and ls

Go on over to the web gui, on the left there should be “System”, clicking it will give you a bunch of options, one of them being “Shell”.

Now you’re going to want to type in cd /mnt/#YOURPOOLNAMEHERE#

Next, you’re going to want to type in ls - this’ll list the files/folders in your currently selected folder. Lets say you’ll get returned “folder1”, “folder2”, and “folder3”, you know that your files are in “folder2”, so you’d next type in cd folder2… now you’ll type in ls again & see what is listed. Keep going like that until you hit the folder that should contain your files & see if they are present with ls.

Edit: Excuse any terminology on this one folks, I’m keeping it simple.

Yes, sorry, I should have know what CLI was but I just CL. I did /mnt/poolname/Media/foldername, then ls

Anyway, after going to my pool and media folders, the only data there is what is left after it went missing. It was ori s only 1 media folder, and thankfully no others

And looking in Storage for the said pool, there are no errors, so why. 64 million dollar question I guess.

Sorry sir - that was then the bad outcome :frowning: I was hoping you’d be lucky it & was just SMB being stupid. Hopefully nothing critical is gone, but let this be a good lesson to setup automatic snapshots asap.

It could be worth making a manual snapshot now. Might be also good to double check you have automated SMART test & scrubs setup.

In regards to why/where the files have gone, donno. No chance you deleted them by mistake? Any other users with more than just ‘read’ access on SMB shares pushing delete by accident? Any chance you’re running Plex & gave it the option to delete files & someone was very silly?

Edit: 1 more stupid possibility; no chance that the folders were moved into another folder? I’m still confused if total space has changed since the files went missing.

Not at my PC. Will have commands for you to try later. Do not delete or format anything.

No guarantee this will work, but it’s worth seeing if your files are still intact.

For each command, replace <poolname> with the name of your pool. You likely need to run these as the root user or with sudo. Some commands might need to be changed for SCALE/CE, since these are in a standard shell in Core/FreeBSD.


Capacity and usage of entire pool:

zpool list -o name,capacity,allocated,free <poolname>



Space and usage information about all datasets and their parents:

zfs list -t fs,vol -o space,mountpoint -r <poolname>



Currently mounted filesystems:

zfs mount | grep <poolname>



Pool history that might involve destructions or renames:

zpool history -i <poolname> | grep -E 'rename|destroy'



Usage of folders that share the same names as their datasets. This command will take a while and it is redundant, since it will need to scrape your entire file tree and lower directories multiple times over:

for ds in `zfs list -r -t fs -H -o name <poolname>`; do du -hs "/mnt/$ds"; done

Put the results inside code brackets. Click the </> button.

As it’s not far off 11pm here in the UK, I’ll post the results tomorrow

thanks

Here is the 1st

Easiest question first. Are you expecting more than 3.4 TB of media and data on your pool?

That doesn’t make sense. Usually the ALLOC of a pool is nearly the same or smaller than the USED of its root dataset. There’s a discrepancy of around 0.7 TB. Other than digging in the datasets for this missing 0.7 TB, the only other place I can think of is a pool checkpoint, which I doubt you created.

I’m really hoping you don’t have a job that takes a new checkpoint overnight, since it would destroy the current checkpoint that might account for the missing 0.7 TB. I doubt this is the case.

I’m just confused how the pool is claiming 3.4 TB ALLOC, yet the root dataset’s USED (which accounts for children and snapshots) is only 2.7 TB.

Is this a mirror vdev? Is this a RAIDZ vdev? If it’s RAIDZ, did you ever “expand” it with an additional drive?

EDIT: In an earlier thread, your WinShare/Media dataset had 2.47 TB USED, which includes all children. Now it shows only 1.91 TB USED. You had also mentioned you deleted a dataset. Are you certain it did not contain media?

According to Storage for the said pool, it says Used 2.71Tb, Available 4.41Tb

The size if the pool is 7.71Tb

Before the data disappeared , there was about 4.1Tb of used space for the said pool

I have x5 2Tb drives in a Raidz1 setup

Regarding the earlier thread about the read only dataset; yes, I copied all the media files from that dataset to an empty one, then deleted that read only dataset, created a new one with the same name , then copied the media files from the other dataset back to the new one.

I hope that makes sense.

Thanks

For information, I am running this cmd now:

for ds in `zfs list -r -t fs -H -o name <poolname>`; do du -hs "/mnt/$ds"; done

I don’t believe what is happening with TrueNAS now. I shut down TrueNAS to check some hardware, rebooted and now both TV shows and Films datasets are empty, all media files gone.

And I forgot tom run a snapshot before I shut TrueNAs down!!

That’s highly irritating. Files don’t just vanish by themselves. First: is your pool usage actually lower now than before?

Does anyone else (or some automation tool) have access to these files?

The pool usage is still the same size as it was before I shut down TrueNAS. The 2 data sets are still empty, but the weird thing is that when I try to copy over a movie file to the dataset, I get a message saying it already there, Also the ‘missing files’ are there in Plex. Confused I will be!!

Also when I check the dataset it says that 331Gb is being used , so the files must be there

That’s a good sign - the files are very probably still there. Where don’t you see them? Via SMB?
