Proxmox Clustering Question

[bengrech]

First and foremost 2 thumbs up for PROXMOX VE which is a fantastic install.

Have a question regarding Clustering and was wondering whether anyone can help.

Had a single machine with PROXMOX running different VMs and disk started playing up.

Quickly setup a second PROXMOX machine, and set first PROXMOX machine as CLUSTER MASTER and second PROXMOX machine as CLUSTER SLAVE.

Migrated VMs from MASTER to SLAVE. I have the following VMs running;

• Plain OpenVZ VMs running on local storage (but with some NFS mounts inside VM)
• KVM VMs running off NFS storage

I would like to reinstall PROXMOX CLUSTER MASTER machine to the latest version on the new hard disks (2 x 2TB with an ARECA 1200 RAID Controller).

What are recommended steps to cease CLUSTER and run second PROXMOX machine independently?

Once I install the latest PROXMOX on the new disks, can I reinstate CLUSTER to shift VMs back?

Your recommendations would be appreciated.

What should I do to the PROXMOX cluster so that I can continue running VMs from second PROXMOX machine, whilst I reinstall PROXMOX on the first machine.
