Hi all! In these days i have configured my second node in proxmox. I'm looking for migrating some CTs to new node but always when via browser interface i start migrating process i see this error:

My nodes are updated at Virtual Environment 5.4-11.

I have missed to say that my nodes don’t have zfs file system, this is a classical installation.

I’ve checked the hard disks and the both SMART status and it’s all ok.

I’ve tried to look on the forum and some users have uses the specific command of proxmox for removing the disk but it doesn’t work.

lvchange -an -v /dev/pve/vm-100-disk-0
    Deactivating logical volume pve/vm-100-disk-0.
  Logical volume pve/vm-100-disk-0 in use.

Can you help me? Thank you!

I've rebooted both nodes and at start on source node i can do it. From browser i've removed from local-lvm the vm-100-data. But why this problem happen? I want to do mmy migration without rebooting every time XD
