Migration and Replication Issue

[nakata720]

Hello everyone !

I have configured a 2-node cluster with QDevice working properly. Now I reached the moment when I have to set up the HA but I am encountering some obstacles.
Here are the configurations I have done till now :

• ZFS local storage (I am using the created one from the proxmox and just added the 2 nodes) Should I stay with local-zfs or add a new zfs directory -> HA-local ?

• Replication job from node1 to node2 on CT-1. And here is the log I got from its execution :

• Created a Datacenter HA group and configured it with my CT. Thats the log I got from one try :

How can I tackle the issue with the Permission denied (keyboard-interactive) between the two nodes. I configured a 2FA with google authenticaiton and I can ssh from each node to each node without any problems with the code provided by the app.

Thank you for your time guys in advance !

Hello everyone !

I successfully tackle the issue with a few lines of code and configurations.

1. Storage : It's recommended to create a separate ZFS dataset for the HA configuration. This way, the HA resources and configuration files are stored separately from the VM/CT (Container) data. Creating a dedicated ZFS dataset for HA can make it easier to manage, backup, and restore your HA settings independently. You can create the new ZFS dataset (e.g., HA-local) and then associate it with both nodes in the datacenter. I created a new zfs directory called HA-local.

2. Permission denied (keyboard-interactive) : I tackle it with a Match directive. Here is how to do it :
nano /etc/ssh/sshd_config
Add the following Match directive at the end of the sshd_config file on both nodes:
Match Address 192.168.90.90 # Replace with the IP address of the other node
AuthenticationMethods publickey
systemctl reload sshd

I hope I helped somebody
