[TUTORIAL] how to change the VMID with ZFS

[maxprox]

HI,
I found no solution to this, so I made one myself ;-)

EDIT on 2019-07-13:

##shutdown the VM
qm shutdown 106

## edit the VMID in the storage line[for me from local-zfs:vm-106-disk-0 to local-zfs:vm-104-disk-0]:
vim /etc/pve/nodes/name/qemu-server/106.conf

## rename the conf file:
mv /etc/pve/nodes/name/qemu-server/106.conf  /etc/pve/nodes/name/qemu-server/104.conf

## list the ZFS  volume or all:
zfs list -t all
...
rpool/data/vm-106-disk-0               1,11G  7,02T     1,10G  -
...

## rename it with zfs rename:
zfs rename rpool/data/vm-106-disk-0 rpool/data/vm-104-disk-0

## host restart is not needed
qm start 104

You made some mistakes.

If you want to change VM ID you need.

1. Turn off VM.
2. Rename VM config file.
3. Change VM disks location ( in ZFS rename )
4. Change config disk location inside VM config file.
5. Start VM

p.s. why a lot of people do server restart? Do you use windows or what?

Do you use windows or what?

That's what I thought too.

I found no solution to this

You found a faster solution for ZFS, but backup&restore works always and for all storage types.

Thank you
p.s.: ;-) yes, also, but loath
I edit my post with shutdown and without reboot

The procedure is not complete, the firewall does not follow.

mv /etc/pve/firewall/106.fw /etc/pve/firewall/104.fw
pve-firewall restart
