Migrate VM between nodes from "local" disk

[Ivan Gersi]

Proxmox allow migrate VM between nodes only from local disk, not from another.
I have a situation.. 1 node with 2 disks arrays, one is classic lvm and 2nd is mounted to dir.
How can I migrate vm from 2nd array smartly? Because I have to move disk of VM to lvm and then I `m able to make online or offline migration.
I`d like to use "best practice" and don`t try to discover wheeel again.

Hi,

You can do this on CLI as the below command:

qm migrate <VMID> <Target-Node> --targetstorage <TargetStorage> --with-local-disks --online

I can`t do this because target machine doesn`t known non local disk. This is "the bug" if target machine doesn`t see 2nd disk in source machine.

root@pve4:/etc# qm migrate 100 pve6 --online --migration_network 10.10.10.0/24 --targetstorage local --with-local-disks

migration aborted

Are you saying that you want to move from 2nd array to 1s array on same node as you want to take advantage of LVM?
If that is the case then under "Disk Action", you can move storage of VM to another array.

No I wanted to migrate from one node to another (pve4 to pve6). I had to migrate vm from SSD_old to local on pve4 firstly and then I was able to migrate to pve6.
