Sau khi update mình nhận được lỗi này
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the RSA key sent by the remote host is SHA256:ETRo3bddIbd52Wl8nvGrj1KffSKV5Ed3jDHV/b0NBGs. Please contact your system administrator. Add correct host key in /root/.ssh/known_hosts to get rid of this message. Offending RSA key in /etc/ssh/ssh_known_hosts:17 remove with: ssh-keygen -f "/etc/ssh/ssh_known_hosts" -R "xxx.xxx.xxx.xxx" RSA host key for xxx.xxx.xxx.xxx has changed and you have requested strict checking. Host key verification failed.
Cách 1: Trên node đang bị lỗi
pvecm updatecerts -f
Cách 2: Trên node đang bị lỗi
systemctl restart pveproxy
Cách 3: Trên Node chính
ssh-keygen -f "/etc/ssh/ssh_known_hosts" -R "xxx.xxx.xxx.xxx"
Done !
