I’m running TrueNAS Scale 25.04.0 and want to move my existing VM Instances from my current HDD pool (data) to a new NVME pool (appsvms) for better performance. Questions: What is the recommended/official procedure for migrating existing VM Instances (including their virtual disks) to a new stora…

[image] TrueNAS 25.04 - multiple virtualization pools Apps and Virtualization I have a TrueNAS box with an SSD pool and a separate HDD pool. I’d like to use zvols on both (importing from TrueNAS 24.10 where I had this setup) in virtualization instances, but I am only able…

I came here with the same question so I will wait for the next version before attempting.

Just updated to 25.04.1 But sadly, I still can’t see another pool under Instances > import zvolumes. There is still only one entry that points to my old pool under /dev/zvol Though I have also tried to replicate my current .ix-virt from one pool (data) to another pool (appsvms) and then set my ne…

Not sure if this is same scenario as others but I also needed to move some VMs to a newly created SSD Pool. This is what worked. Info: TrueNAS Scale: 25.04.1 VMs are in pool A (data pool with spinning disks) – using generic labels for illustration VMs to be moved in pool B (newly created mirrored…

Tried, step by step. But ultimately the disks are unable to boot in any way. :flushed: Cloned the disks using 2nd option given in clonezilla that is disk to disk method.

Did you have any errors during cloning process? In one cloning instance I had similar issue where it failed booting (there were errors during cloning). Re-cloned with the following option (this option can be selected after choosing source and destination disks) while accepting suggested error/repai…

Hey There, I just went through this same issue. The key for me was to ask ChatGPT how to do this from the command line using the “incus” tools as this is what drives the Instances tool in TrueNAS. It was all pretty straight forward in the end: # 1) Stop the VM so the volume isn’t in use incus sto…

Hi folks, @pdanz approach didn’t work in my case (move VM from one pool to another) because incus storage volume copy works for custom volumes, not VMs. However, I was able to move VM to another pool with commands: # 1) Stop the VM so the volume isn’t in use (feel free to use UI for this) sudo i…

By merging and following up by post @pdanz and post by @Antoshka I was able to move the .ix-virt and the VM instance / container to the new pool. Great. Thank you very much both of you.

Necro-ing this thread (since it ranks well in search results) to share my success story and instructions. I used the GUI for my migration. Go to Virtual Machines (called Virtualization in TrueNAS 24) and turn off the VM by switching its Running toggle to the off state. If the VM has an interface…

This post have also mention the same issue of not showing other pools in Import Zvol. And it said this functionality will be available in 25.04.1

So finger crossed
