Note: Reinstalling the system normally will only resets the configuration and permissions but does not delete the data on the hard disks if they have been on the device before. BUT to prevent accidents, it is recommended to backup your data before reinstalling if conditions are sufficient. If you have any questions when operating the above steps, please contact us in time.
After installation-auto restart-setting the initial account password, if it prompts to create a storage pool or initialize raid, please stop the operation immediately and contact our support team to assist you remotely.

Hi all

Warning: include_once(): Failed opening 'include/app.php' for inclusion (include_path='.:') in /usr/www/Enter.php on line 2

Fatal error: Uncaught Error: Class 'raid' not found in /usr/www/Enter.php:4 Stack trace: #0 {main} thrown in /usr/www/Enter.php on line 4

I don’t know how solve this issue , I tried method 2 but , when I try to reinstall all the system says me that can’t access to the network to download the version , I tried also manually with the program that I downloaded from the site but nothing… the installation arrive to 55% and failed.
How can I fix it ?

Can you tell me which step of the instruction guide on the first page has you wondering?

Method 2:

4. Wait about two minutes, after the network light is on, use TNAS PC to search for your TNAS device;

TNAS device not found. I have a F2-221 with TOS 5.1.24. If i turn on my device with all hard drives inserted TNAS PC can find it.

I need to restore the NAS after the "user doesn't exist" bug.

Your post does really not give any clarity: Is the network light "on"?

If i turn on my device with all hard drives inserted TNAS PC can find it

:Did you really mean that? in which case what is problem? I would guess, in first instance, if network light is 'on', all drives inserted (and working) and NOT found by TNAS PC then possibly the NAS has aquired an ip address that is not on your network segment. Can you check network via your router client/device table? Or other means? (If you don't understand that, ignore it.

Hello.

Yesterday I got "user does n't exist" bug, so as I understand, I need to reinstall TOS.
As of now, I don't have access to TNAS via Web browser and mobile app. Otherwise I have access through Samba (network disks connect and work just fine as usual), ssh (also work fine). Plex server is running and accessible from PC and TV in network.

As I understand, after reinstall all data on RAID should be safe (and I just don't have any sufficient disk space available to backup it from TNAS, so I just can't follow recommendation to backup data), but system files and databases will be deleted.

So the question. Is it possible to somehow copy (via SSH) Plex mediainfo databases before reinstall? My Plex database for some specific reasons was largely manually made (posters uploaded manually, description wrote manually etc.), it took some time and work and I would like to keep it some way if it's possible and not to re-do it again.

You can try to log in to SSH. If you can log in to SSH successfully, you can use Linux commands to copy the Plex library file to the volume directory or USB device. (TOS4:/mnt/md0/User/plex TOS5:/Volume1/Plex) viewtopic.php?f=78&t=2350

I seem to be having a similar issue to others trying to do a software update from the GUI. It gets as far as "unzipping the software package" and hangs at that. I have the F4-422 and am trying to update from 4.2.40 and have tried both 5.0.176 and 5.1.24 update packages from the download page

Did you increase the size of your root partition from 2gb to 8gb before updating TOS?
