Flashed H330 mini to HBA firmware and all is well. PCI Passthrough is working as expected for truenas VM. Thanks for your help

Hi all, first off, I'm a noob and gradually learning this stuff, so thank you ahead of time for your patience and help with getting me through this Secondly, I promise I've spent days researching the answers myself before creating this thread. I've followed the guides, the official docs and I...

Yes, TrueNAS is still working with virtual disks. Only way for the guestOS to directly access the real physical disks is to use PCI passthrough of the whole HBA or individual NVMe disks. Just don't work with sda/sdb and so on at all. If you need to do something on the CLI use /dev/disk/by-id or...

Without PCI passthrough of NVMe SSDs or an HBA there is no working SMART from inside the VM so TrueNAS can't monitor the disks health nor send warnings when a smart selftest fails. Then you need to set up external monitoring/alterting (via CLI) on the PVE host to monitor your disks health...

Check your IOMMU groups. That HBA is probaly sharing an IOMMU group with some important onboard devices and as you can only passthrough all devices of the same IOMMU group at a time (which are then not available anylonger to the host). Check output of pvesh get /nodes/{nodename}/hardware/pci...

Hey just FYI I was have all kinds of problems with my server build trying to get TrueNAS scale working as a VM in Proxmox and getting the HBA to passthrough. Not sure if this will help you but one of the major problems was that when I had physically built the server I had 6 HDDs intended for my...

Edit: Not the PCIe-passthrough is the culprit, but the: hugepages: 1024; most likely in combination with root on ZFS, see: https://forum.proxmox.com/threads/vms-with-pcie-passthrough-do-not-start-anymore-on-pve-kernel-6-5.136741/post-606900 (Changed the thread title accordingly.) /E As...

Both of my VMs with PCIe-passthrough (which run perfectly fine on all the 6.2 kernels) can not start anymore on the 6.5 kernel. :( One of them, as an example:

Hello, I have two dell servers, a R730XD and a R720XD both with quad SFP 10Gb/s ports connect to a single Cisco Nexus 3172T on two QSFP+ ports. The 4 ports on each server are placed in a LAG doing LACP and hashed at layer2+3. The Cisco port channel is a trunk carrying the same vlans to each...

Yes, thats why you usually buy a HBA card to passthrough, so you don't have to passthrough the onboard disk controller where your system disks might be attached to. Or you install PVE on NVMe SSDs that aren'T using the disk controller anyway.

Ah yes I forgot to mention that. I did try wiping from the PVE host itself, That removed some /dev/sdx1 and /dev/sdx2 partitions, but again no luck when trying to create the pool afterwards. Although from the PVE host each disk appears clean.

Did you also try to wipe the disks from the PVE host? Keep in mind that when working without PCI passthrough of a HBA your TrueNAS is always working with virtual disks and not the real physical disks.

Thank you wbk! I tried rescue boot from usb, also no luck :) So installed proxmox from scratch (again), because this system isnt mission critical yet and wont be before i got it working. Have to do back up's this time so i dont have to configure and install everything again. My set up is...

Hi there, I'm doing something quite trivial I have this controller and 4 HDD disks attached to it: root@sofx1010pve3307:~# dmesg |grep 2008 [ 0.256490] DMAR: dmar0: reg_base_addr fed90000 ver 1:0 cap d2008c40660462 ecap f050da [ 3.309755] mpt2sas_cm0: LSISAS2008: FWVersion(20.00.07.00)...

indeed the default lvmthin is great. truenas require zfs and it's for enterprise with integrity requirements, which require datacenter ssd with PLP protection to allow reliability and durability. passthrough disks with cli qemu set /dev/disks/... isn't recommended and you loose flexibility. Only...

Yes, passthing through a HBA is like TrueNAS running bare metal directly accessing the real physical disks. Every OS with ZFS support could import the pool. Not sure how TrueNAS handles ZFS pools not created by TrueNAS. Best you ask that in their community forum. When passing through...

Thats an option. But ZFS got terrible overhead and overhead isn't adding up but multiplying (so exponential growth). So it's not a good idea to run ZFS on top of ZFS and ZFS is want you need for TrueNAS. So I would either passthrough a whole HBA card (or alternatively individual disks if PCI...

That sounds like a nice low-power home server. Would be interested to hear what the power consumption is when running idle and under load. So hard to find an energy-efficient machine that checks all my requirements like dual NVMe or SATA, quiet, ECC RAM. That's not a lot of RAM for all those...
