Need Help! All VM cannot start (status 1)

[cahsobo]

I've been in a dead end. The VMs cannot start at all suddenly since few days ago. Everytime I tried to start it, it always failed with an error message below:

Error: activating LV 'pve/data' failed: check of pool pve/data failed (status 1). Manual Repair Required!

Please help!!

Sound like your LVM-Thin pool storing your VMs got corrupted. I hope you got recent backups?

No. I don't know how to make backup
It was a brand new NVMe SSD. Is there any way to recover it?

Or should I just reinstall proxmox and reconfigure from the start?
