TrueNAS Scale 24.10.2 VM installer of Ubuntu 24.04 fails (Solved)

[ThatGuy]

Hi, I upgraded to Electric Eel a while ago with existing VMs without issue. The problem appeared when I wanted to resize my virtual drive, and to do that I tried to boot the VM with a LiveCD iso. The LiveCD boots fine until the “preparing Ubuntu” GUI installer appears then it goes black.
No issues with booting from the installed Ubuntu OS in the VM, but I can’t resize a mounted partition.

Sorry if the topic is confusing. I am just trying to use the installer to change the partitions, and not trying to install/reinstall.

OS Version:TrueNAS-SCALE-24.10.2
Product: X10DRi

Memory:126 GiB

VM settings:

ensure display device checked

Edit: spelling

If you’re using LLVM (which is the Ubuntu default) these instructions work well.

HOWTO: Resize a Linux VM's LLVM Virtual Disk on a ZVOL

If you have a Linux VM, which uses the LLVM filesystem, you can easily increase the disk space available to the VM. Linux Logical Volume Manager allows you to have logical volumes (LV) on top of logical volume groups (VG) on top of physical volumes (PV) (ie partitions). This is conceptually similar to zvols on pools on vdevs in zfs. This was tested with TrueNAS-CORE 12 and Ubuntu 20.04. Firstly, there are some useful commands: pvs - list physical volumes lvs - list logical volumes lvdispl…

Thank you that worked! Eventually I might want to expand it to beyond the MBR 2.2TB limit but that sounds like a reinstall, which can’t be done with the installer not working.
