In order to FORCE local node operations : pvecm expect 1
Then you will have to pay attention to what you are doing in /etc/pve as it won't be synchronized to other hosts.

Hello and thank you for your advice. Backup data is a second nature to me . however pvecm expect 1 does not solved my problem. To start in standalone mode :

pmxcfs -l

Then in have édited the corosync.conf file to increase the voting value to 2. Then I have restarted the cluster Service. Quorum is now ok because it is read from configuration file which is not more synchronized. I will revert after to resynchronize the other node.

Thanks!
