Boot TrueNas VM from the same SSD proxmox is installed

[fahadshery]

Hi all,

I am looking for an opinion on installing TrueNas VM on a local-lvm storage?
The reason for this is that I have 2 x SAS3 HBA's with 8 disks attached to both of them. I already pass one HBA to TrueNas VM and the other one is hosting a local ZFS pool within proxmox which I use to stand up any VM's / containers within proxmox. But recently, I have been thinking to pass the second HBA to TrueNas as well so that it manages all my ZFS pools.

So if proxmox reboots, my VMs who are hosted on TrueNas can't start until TrueNas VM is up and running.

Once the TrueNas VM boots up, then I could mount iSCSI / NFS storage within proxmox and then start all subsequent VMs from those.

My local lvm has free space of 32G which I never used previously anyway. This local LVM is obviously on the same SSD that I boot my proxmox from.



Any opinions on this approach? Pros and cons?

Thanks for reading.

Cheers,

Why not just delay the start of the VMs that require a booted TrueNAS VM?

that's exactly what I meant
Boot proxmox. Then boot TrueNas VM. Once up and running, then boot up the subsequent VM's

Under "Options" every VM got a "Start/Shutdown Order" where you can set the order the VMs should be started and you can also set a "startup delay" there.
