Error migration the vms beetween 2 hosts in HA

[elleti]

Hello everyone,
i tried to solved this error by myself but nothing works, i changed something in these 2 hosts before having this error.
PROXMOX VERSION: 8.2.7
task started by HA resource agent
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @

Tell me if you need more info about the cluster and the 2 hosts pve.

Thank you guys

Seems an issue with the ssh keys.
Try to do ssh between the hosts in this cluster. It show similar message

Try as mentioned in the error.txt to run:

~ # ssh-keygen -f "/etc/pve/nodes/pv2/ssh_known_hosts" -R "pv2"

Could you share the output for it

 

[elleti]

I ll share it tomorrow because i dont have the access from home, thank you bro good night

Could you share the output for it

Sorry, via ssh from pv2 to pv1 i can access but from pv1 to pv2 says : Permission denied (publickey).
This is the output:
root@pv1:~# ssh-keygen -f "/etc/pve/nodes/pv2/ssh_known_hosts" -R "pv2"
# Host pv2 found: line 1
link /etc/pve/nodes/pv2/ssh_known_hosts to /etc/pve/nodes/pv2/ssh_known_hosts.old: Function not implemented
root@pv1:~#

Aha this make sense, Proxmox ve uses pmxcfs, its FUSE-based filesystem that stores configuration in a SQLite database and synchronizes it across the cluster.
There's a pve command to correct this, I will look for it and update you

thank you very much

thank you very much

ehy i fixed this problem right now, many months ago i configured the routing rules for the ssh access in the pv2, i removed the rules and i did this ssh-keygen -f "/root/.ssh/known_hosts" -R "pv2".
Thank you for your support Sir

You can attempt running the below command [0] on all cluster nodes:
~# pvecm updatecerts

This should recreate the node specific ssh_known_hosts file based on its SSH key.

See man pvecm [0] for more details.

Glad you managed to solve it! I didn't notice your reply before my last answer, but yeah, I'll keep it so it's easy to fetch that command in the future hehe
Thanks for sharing the fix.
