Hi all,

The network drive is suddenly displaying incorrect storage space.

Yesterday, it showed 7.22TB used out of 11TB, but today it’s showing 140GB used out of 391GB. 

 

I’ve tried disconnecting and reconnecting the drive, recreating the pool, restarting the array, and running a check—nothing changed. 

Despite this, all files remain accessible without any issues.

Any idea what might be causing this?

Are you sure your network drive isn't mapped to a zfs dataset?

Attach Diagnostics to your NEXT post in this thread. 

Also, Unraid V7 doesn't require an array so you can get rid of that USB  disk1.

Together with the diags also post the output from

 

zfs list

 

Thanks for the quick response!
I'm running Unraid v6.12.10, so it won’t let me start without an array.

Errors: No known data errors.

The Media share reports 151GB of free space. Below is the share configuration for the "Deadpool" pool.

I've attached the diagnostic ZIP file.

 

Previously, Unraid threw a 500 error on the web server, and I lost access to unraid GUI admin panel except Jellyfin. After rebooting the NAS, Unraid wouldn’t start, so I had to change the usb key, format it and do a full reinstall, which fixed the issue. 

 

I haven’t modified the configuration since, yet the reported size changed suddenly two days later.

 

I got the Unraid license "basic" with LINCSTATION N1.

Sorry I forgot, here is the result :
 

root@hel:~# zfs list
NAME             USED  AVAIL     REFER  MOUNTPOINT
deadpool        6.57T  3.88T      140K  /mnt/deadpool
deadpool/Media  6.57T  3.88T     6.57T  /mnt/deadpool/Media

Looks normal, the only thing that is not correct, is that the media share also exists on the flash drive, but I don't think that would cause that issue, still, delete /mnt/disk1/media, assuming there's nothing important there, and retest.

I will give a try thanks! I might just get a license and upgrade it to v7, hopefully it might fix the issue.

 

Looking at the screenshot, Unraid is showing /Media with 151GB free (when I should have like 3tb), so it's pretty strange.

Yeah, and since the share also exists on the flash drive it would be included, still not clear where that value comes from, but it may not be an issue with v7

I updated to v7.0.1, but I couldn’t figure out how to start the pool without the array. 

That said, after the upgrade, the disk sizes are now displaying correctly - so everything’s sorted!

Thanks!

You have to set the number of slots for the array to none.
