Hello, I want to migrate an online virtual machine from one node to another and get the message like below. What is going on?

Task viewer: VM 1008 - Migrate

OutputStatus

it seems on the target node is already an logical volume 'vm-1008-disk-1' in the volume group 'pve', so it aborts instead of copying it over
 
the first question to answer would be 'why is it there',
you could of course delete it, but then the (possibly important) data of it is gone
 
Well I only have 4 nodes in the cluster and 3 that is trying to migrate the machine I have the same message.

Hi,
online migration without --with-local-disks??

Are the local-lvm:vm-1008-disk-1 is active? Post the vm-config please:
Code: 
cat /etc/pve/qemu-server/1008.conf
and also the lvs-output from the source and destination-node
Code: 
lvs
Perhaps the content of /etc/pve/storage.cfg will be helpfull too.

Hi,
you use the disk on the nfs-storage not on the local-lvm.
Due the missing "unused0: local-lvm:..." looks that you manual edit the config-file!

the logical volume is on both nodes active but not open - mean not in use.
So it's should be safe to remove the lv vm-1008-disk-1 on this (all?) nodes.

I understand that in this situation I have to remove these local disks from the node as seen after executing the lvs command?
