Migrate TrueNAS VM to Proxmox VM

After Proxmox installed, I also migrate TrueNAS VM to Proxmox as VM for both Ubuntu VM and Windows 10 VM.

Copy zvol to a file and transfer to Proxmox server

The zpool volume device is located in /dev/zvol/<zpool_name>/<zvol_name>. Create disk image using following command.

dd if=/dev/zvol/pool0/server-xxxxxx of=/tmp/server.raw bs=8m
scp ...

Another way to transfer

dd if=/dev/zvol/.... bs=8192 status=progress | ssh root@proxmox 'dd of=....raw bs=8192'

or

dd if=/dev/zvol/.... bs=8192 status=progress | gzip -1 - | ssh root@proxmox 'dd of=....raw.gz bs=8192'

or

dd if=/dev/zvol/.... bs=8192 status=progress | gzip -1 - | ssh root@proxmox 'gunzip - | dd of=....raw.gz bs=8192'

Transfer raw file into Proxmox server

Create Proxmox VM

• Create a VM with OVMF (UEFI) if TrueNAS VM is using UEFI

• Remove VM disk

• Use following command to import disk

qm importdisk <vm_id> <raw_file> <storage_id>

For example

qm importdisk 100 vm.raw ds1812-vm_nfs1

• Go to VM hardware page

• Select unused disk and click Add button to add disk into VM

  • For Linux, select SCSI as controller
  • For Windows, select SATA

• Select Options => Boot Order to check the iscsi/sata controller

Boot TrueNAS VM
