[SOLVED] Avoid Proxmox "cache" on NVME

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?

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.
