If Proxmox using NVME hang (all icons grayed) then I do hard restart, then vps (in my case LXC) will back to several days ago.
So any websites in VPS will back to several days ago.

How to avoid this?

NB:
Proxmox 5.4.3
VPS created on secondary disk using NVME with ext4 file system
 
Code:
~# smartctl -a /dev/nvme0n1
smartctl 6.6 2016-05-31 r4324 [x86_64-linux-4.15.18-12-pve] (local build)

Time to replace with the new one :)
 
consider a used intel data center grade nvme . DC models needed.

note if you get used make sure it can be returned - incase smartctl shows fail OR high % Percentage Used.
