Complete Guide to TrueNAS CORE Virtualisation Under Proxmox
Conclusion
There you have it. running TrueNAS CORE inside Proxmox. It looks overly complicated, why do this when TrueNAS SCALE can do all that? The answer is simple - ECC. If you followed my lead and uses normal RAM, you would notice something quirky when you’re looking at the TrueNAS CORE management UI.
And it is Multi-bit ECC.
Handle 0x1000, DMI type 16, 23 bytes Physical Memory Array Location: Other Use: System Memory Error Correction Type: Multi-bit ECC Maximum Capacity: 48 GB Error Information Handle: Not Provided Number Of Devices: 3
For some reason, in QEMU/KVM virtual machines, the memory is ECC. And this is the reason for this NAS build. With normal RAM modules, I do not think TrueNAS scale will have ECC protection for my zpool.
It will be great if this is ECC done in software, it can also just be a bug in the QEMU/KVM subsystem. It is still early days as I have only run this NAS for close to 2 months now. Time will tell.

I was writing a similar guide for the teens that come to the IT workshop in our charity for children association and I found your guide. You did fantastic work. This is very helpful. 🙏🙏🙏🙏
