BTRFS Volume no more accessible, Help!

[gmastellone]

Hi, I have a TNAS F4-421, TOS V. 4.2.39.
I have 2 Volumes:
Main Volume with 2x WD Red 4TB in RAID1, in BTRFS
Secondary Volume with 2x WD Blue 1TB in RAID 0, in EXT4

From yesterday I can't access the Volume 1 anymore, in TOS I see it, the status is "good", with no errors, but I don't see it anymore in the file manager nor from computer in the network.
I only can access the secondary Volume.

Unfortunatelly all my personal and working files are in the main volume, so I need to access it as soon as possible.

I think files are ok, since in the TOS desktop it says that the volume 1 has 400 occupied GB.. but I'm unable to access it.

Can someone help me please?

Best regards,
Giovanni
