Data missing after ZPool import

fatsoda · January 11, 2025, 9:37pm

Hello

My *nix experience is what i would call medium-level expired (used to work on CentOS as webhost admin) so be gentle, but i can follow most instructions.

I recently moved from a old HP proliant with Freenas to a new build intel desktop, i5 12400 on an Asus b660m, 32 gigs of ram. I installed TrueNAS

I moved 4 x 8 TB drives over to the new installation and imported the pool

I cant see any media files in the Plex install, or in CLI / Shell

When i do a ZFS mount I see the following (apologies newbies cant link images or upload txt files)

Click to view "zfs list"

I installed TrueNAS SCALE 24.10.1

neofusion · January 11, 2025, 9:47pm

Where did you store those Plex files?
On it’s own dataset under Primus, or somewhere else? Is this dataset missing from the list you provided or is it there but empty?

fatsoda · January 11, 2025, 9:57pm

The files were under mnt/Primus/winder

What is the output of this command?

zfs list -r -t filesystem -o space Primus | grep -v \.system

Paste the code within code brackets, like this:

```
paste in here
```

I think i got the brackets right

Those are supposed to be “backticks”. Like this: ```

You did three dots.

It looks like your media files are saved in the plexmediaserver_1 dataset.

What happens if you list under /mnt/Primus/jails/plexmediaserver_1/

ls -lh /mnt/Primus/jails/plexmediaserver_1/

winnielinnie · January 12, 2025, 3:20am

Oh no. I just realized something. You have been saving media files directly in the root dataset? This will cause all sorts of permission issues (and is not good practice).

ls -lh /mnt/Primus/ | grep -v 'iocage\|ix-apps\|jails\|winder'

fatsoda · January 12, 2025, 3:24am

The files were stored in /mnt/Primus/winder/

Am i screwed?

winder as a folder, not a dataset, apparently.

Not really. But there’s a lot going on.

You have an ix-apps dataset, an iocage dataset, a jails dataset, and .warden datasets throughout.

This must be from quite an old FreeNAS system.

I honestly don’t know what is supposed to be what, or even which “apps” are running from where.

I don’t know what winder (or its children) are supposed to be. You will need to manually unmount Primus/winder, which is hopefully a “safe” action and won’t break or crash anything. (I don’t know what apps or services are using it.)

This requires bypassing the GUI.

zfs umount Primus/winder

Just know that you might bump into issues.

If it safely unmounts, try checking again under the winder “folder”:

ls -lh /mnt/Primus/winder/

EDIT: For the “unmount”, I would stop any shares or services that might be using the path, and even unmount each child, one by one, under the winder dataset, before unmounting winder itself.

fatsoda · January 12, 2025, 3:36am

It is quite old installation, had it running over 10 years ++? started off with 4 x1tb drives etc

Well even if it screws it, i dont have anything now, also thanks for the help.

threw no errors.

worked with following returns

Say hello to your files.

How do you want to proceed? Would you like to “move” them to live under the dataset winder? Being in the root dataset is not a good idea.

I also notice you don’t have a user assigned to UIDs 1000 and 972.

Those users will need to be created in the TrueNAS SCALE GUI. For some reason (I still don’t know why), the first user created in SCALE starts with UID 3000 by default.

fatsoda · January 12, 2025, 3:56am

Lets move them to winder (if thats not the prime data set)

I have the following users now

root 	0	    Yes	root	Has Allow List, Full Admin
donkey2	972	    No	donkey2	N/A
donkey1	1000	No	donkey1	N/A
filac	3000	No	Filac	N/A

Before doing so, let’s check some prerequisites.

zpool get feature@block_cloning Primus

zfs list -t filesystem -r -o name,encryption,recordsize,compression

To make sure that winder is still umounted:

zfs mount | grep winder

Everything appears ready.

One more test before proceeding.

First, make a temporary checkpoint on the pool:

zpool checkpoint Primus

Then, rename the winder folder to winder_old:

mv -v /mnt/Primus/winder /mnt/Primus/winder_old:

Then remount the winder dataset:

zfs mount Primus/winder

Then, check the pool’s block-clone usage:

zpool get bcloneused Primus

Then create a 4-GiB file of random bits inside the winder_old folder:

dd if=/dev/urandom bs=1M count=4096 status=progress of=/mnt/Primus/winder_old/bigfile.dat

Then copy this file into the proper (dataset) winder location:

cp -va /mnt/Primus/winder_old/bigfile.dat /mnt/Primus/winder/

Now check the block-clone usage on the pool again:

zpool get bcloneused Primus

You can delete the bigfile.dat and its copy if it was a success.

Be careful when using the command-line!

EDIT: You might have to use sudo on some commands, depending the permissions.

EDIT 2: Please create a checkpoint for the pool before proceeding!
