解决cluster not ready

解决：Cluster not ready – no quorum? (500)

First we login to the Proxmox server. Then we check the state of the cluster using the command

pvecm status

From the result, we find that the Quorum activity is blocked. Thus we execute the below command to change the votes from 2 to 1.

pvecm expected 1

After executing the command we will be able to delete the VM. If the VM gets locked during the process, we unlock the VM using the command

qm unlock 

Then we delete the Virtual Machine.

Cluster not ready due to corosync
Another reason for the error is when the corosync is incorrect. Our Support Engineers analyze the corosync configuration file. The configuration file is present at the location

/etc/pve/corosync.conf

We stop the corosync service first by running the command.

systemctl stop corosync.service

Then we make the required changes in the file. After making the changes we start the service back.
