Hey all,
I recently posted an issue at Proxmox forums (Hard drive passthrough issues | Proxmox Support Forum) regarding an issue with hard drive passthrough.
To make it a little shorter, I will try to summarize:
HW:
Dell PE R740xd with HBA330
2 x Kingston SSD DC600M 960Gb. For Proxmox boot and 2 VMs (Windows Server and TrueNAS)
9 x WD HC330 10TB. Just Storage.
160 GB ECC Ram.
…
The thing is, I wanted to passthrough the drives to TrueNAS, and so I did, and I can see the drives in TN:
The issue is that trying to do a SMART test I get this message:
Given what I’ve found, this sounds like I should do the passthrough of the whole HBA330, not the drives-by-id, which is an issue because those Kingston SSDs are too connected to the HBA through the server backplane, so I cannot “unplug” them.
So, if I do the whole passthrough, I cannot use the SSDs for booting and I want to have redudant boot volume. I could use one of those nvme carrier cards, but read that this server can be picky with other types of booting (else I should find a BOSS card but that is an issue at this time).
If I want to have redundant boot, and I cannot to a disk-by-disk passthrough, then it seems that my only choice is go bare-metal, which is really not my first option as I believe that bare-metal is a waste of resources, and because I would be using the DC600M drives as TN boot, which is like using Formula 1 tyres in a bicycle, but at least that would allow to go on with the project.
To summarize my options
- Do the disk-by-id passthrough, but loose the smart data at TN level
- Go bare metal and use the SSDs as mirrored boot.
Feel free to add more options and corrections.
Now that I think about it, a BOSS card would be of no use for a Proxmox install as I would have to pass the whole HBA, loosing the access for the SSDs to use them for VMs.
Thank you!
