[SOLVED] Error by vm online migration

Jun 12, 2020

I am currently not able to online migrate vms on one of our PVE enterprise cluster. (Offline migration works fine).

task started by HA resource agent

The network and corosync config looks fine, can also switch between the cluster nodes via ssh.

cat /etc/pve/corosync.conf
logging {
  debug: off
  to_syslog: yes

nodelist {
  node {
    name: vmp01
    nodeid: 1

I have already check the following Post but they didn`t help:

PVE Version
pve-manager/7.4-15/a5d2a31e (running kernel: 5.15.108-1-pve)

All nodes has been updated and restarted.

Any Idea to solve this issue?
do you have any special settings for SSH, like a banner? Can you share the log of the VM 213 - Start task on the target node? Are you using the secure or insecure setting for migration, check in Datacenter > Options > Migration Settings?
Hi Fiona,

thank you to your message.
We have renewed the keys even if we where able to connect to each systemby ssh (inside the cluster), this seems to relove the issue.
