When using ZFS it's highly recommended to: 1.) not use SMR HDDs (but CMR HDDs and ideally with additional SSDs as "special" vdevs) 2.) not use consumer grade SSDs (but enterprise grade with power-loss protection) So keep that in mind when buying new disks in case you want to make use of TrueNAS...

There is virtualization overhead, as your TrueNAS VM then still is only working with virtual disks that are mapped to physical disks, instead of direct access to the real physical disks you would get with PCI passthrough, but the overhead is quite small. Its more about stuff like that TrueNAS...

Will work but ZFS got terrible overhead and overhead is multiplying and not just adding up. So ZFS on top of ZFS is a bad idea and I personally wouldn't do that. Would only make sense if you want to migrate that VM between nodes where you wouldn't want to have hardware dependencies. Otherwise I...

Yes. Yes, because you avoid nested filesystems as the ext4 and qcow2 would add unneccessary additional overhead. Keep in mind that you: a) can only passthrough whole IOMMU groups, so the HBA needs to be connected to a PCIe port that is directly connected to the CPU and not to the chipset as it...

Thanks for this advice. Just to be sure: I think my plan above will not involve (ZFS on top of ZFS) since Truenas will be on another drive. Also I did understand from your reply that giving truenas my whole drive is better than making an ext4 drive then make a virtual drive inside it for...

Yes this is what I intended, in fact I want to pass my hba controller to Truenas. Anyway I hope that means everything else is OK : )

Not really the "real" disks. TrueNAS will still handle QEMU virtual disks with that. For real physical disk access PCI passthrough of a NVMe SSD or HBA is required: https://pve.proxmox.com/wiki/PCI_Passthrough But still better than ZFS on top of ZFS or nested filesystems. When using Disk...

Hello everyone, I hope you're all doing well. I've had successful experiences using Proxmox on various machines in the past. However, I'm currently facing some issues with my HP Gen8 Microserver. I've installed an LSI SAS 2008 HBA with the intention of passing it through to a TrueNAS VM for disk...

Did you enable PCIe passthrough as per the Proxmox manual? Without a clearer description of the failures, it might just be a configuration mistake or maybe you need a motherboard BIOS update. Did passthrough of the device give you trouble or could you not enabled VT-d? Do you known that Proxmox...

Hi My server is DL380p gen8 server, and I did read about and test various solutions but ALL of them failed. I must admit that most of them are about GPU passthrough, and I just need to passthrough my p420i controller from proxmox to truenas (and a sas hba later). So is there any proven way to...

Hello all For the past month i have moved all my trunas scale, home assistant and opnsense to my dell r720. It al works fine unless i screw it up (which i do often when i tinker). As mentioned My proxmox server (8.0.4) has 3 vms opnsense (currently not fully configured or activated unless...

So basically I need to get a new motherboard, processor and a HBA card, to solve this problem. I currently have another Proxmox server that has better specs. It sounds like I need to get the storage moved over to that server along with changing to an HBA card, then pass that HBA through to the...

With that much disks I would have bought a PCIe HBA card for PCI passthrough. That is the only option how your TrueNAS could directly access the real physical disks without additional overhead. Now your TrueNAS is still working with virtual disks that are mapped to the physical disks. 15 disks...

I have the 2nd R730xd almost fully setup. I am trying Chia 2.0 & going to use Bladebit to see how the compressed plots go using that. I switched what I was doing from the NetApp connected to the 1st R730, so I would have a 2nd server to keep backups of my VM's on, in a cluster. The next thing...

Were you able to make any progress? I installed the same HBA card and can no longer boot it caused a boot issue. Removing the card and deleting the vm passthrough config resolved the issue. Seems like a different card might be necessary.

Das ist halt ein komplexes Thema. Da gibt es keine beste Lösung für alles. Egal wie du das angehst, du wirst immer auf Probleme treffen wo etwas dann nicht geht. Nur du kannst deinen exakten Anwendungsfall einschätzen und musst selbst wissen was du für Kompromisse bereit bist einzugehen. Mehr...

Brand new install of Proxmox on a R720 PowerEdge, everything up-to-date. 2 x SSD as mirror: - Proxmox - TrueNAS VM 4 x SSD as RAIDZ2: - containers - VMs In TrueNAS, I passed through the 4 SSDs (cannot HBA/LSI passthrough because I only have the one controller). Created a RAIDZ2 pool and some...

Looks like if my PCIE passthrough is switched on then some of my HDD's disappear and the one U.2 on M.2 also disappear No HDD TrueNas can use the HBA plugged into PCIE TrueNas has error of MPT Bios fault GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on video=efifb:off" No HDD TrueNas can use the...

This is great feedback, thank you so much for taking the time to share!

For ZFS (the software raid TrueNAS and PVE are using) you usually don't want QLC or consumer SSDs which those NV2 are both. Proper SSDs would be something like a Samsung PM9A3/PM983 or Micron 7400 PRO/7450 PRO/7400 MAX. Then I would get a LSI HBA card with PCIe passthrough. Disk passthrough is...
