[Help] Volume1 was full => restart NAS => Volume1 displayed corrupted

[ind57]

Hello,
The volume was full and TOS 6 became read only
I wasn't no more able to delete snapshots
I then restarted the NAS
Then the Volume1 was displayed as corrupted => does it mean that all my 5,3TB data are lose?
when I try via ssh to remount Volume1:
...@TNAS:~# sudo mount -o rw,usebackuproot,nologreplay /dev/mapper/vg0-lv0 /Volume1
mount: /Volume1: must be superuser to use mount.
...@TNAS:~#

==> I think Volume1 is not corrupted but TOS cannot mount it
How can I mount Volume1 at least to retrieve all data please?

NAS SSD 8 plus with 4 SSD of 2TB
TOS version 6.0.794

Thanks in advance for your help,

The initial account created on the NAS for SSH login is a super administrator with full privileges. You can execute commands directly without ‘sudo’.

You can use this command to mount: mount /dev/mapper/vg0-lv0 /Volume1

Good morning,
I have the same problem. The root directory was full. After reading on the forum, I deleted files via SSH and restarted. When I opened it, I found all the volumes corrupted. I have an F6-424 Max with two 2TB NVMe drives (system) and two 22TB mechanical drives (data).
What can I do to fix it? Should I delete the volume and recreate it from the TOS interface? Would I lose any data?

Nada, ya lo he solucionado usando la IA. No he perdido los datos, pero he tenido que instalar y configurar muchas cosas.

Hello Jaguera,
Personaly I have sent the system report and received absolutly no answer...
In order to retrieve my data, I create a linux bootable usb key and launch the NAS from it. Then I mounted the volume on this linux and retrieved my data to my PC (chatgpt and gemini are your friends). And then I reinstalled the NAS.
Good luck...
