Problem with lvm. Logical volume in use

I have a kvm-cluster and system datastore on SAN LVM.
The volume group shared on 2 nodes in the cluster.
I want to migrate my VMs from the one node to other.
But I get the error.
Logical volume in use:

  • sudo lvscan
  • sudo lvchange -an /dev/vg-one-128/lv-one-127-0
    Logical volume vg-one-128/lv-one-127-0 in use.

Why it happened? And how can i fix it?

Can you paste here relevant part of the logs and also the datastores configuration?

Thank you for reply.
The problem is solved.
I had wrong NFS configuration for the datastore.
