[pve-devel] Create new fresh Proxmox cluster

[lyt_yudi]

In my env,from forum.proxmox.com someone to suggest
you can try it just this:
1. stop cman of all nodes
2. stop pve-cluster of all nodes
3. then start in local mode
# /usr/bin/pmxcfs -l
4. remove or modify your cluster.conf,just one of the node cluster.conf,and then copy to other nodes
5. stop and start the cluster file system normally
# /etc/init.d/pve-cluster stop

# /etc/init.d/pve-cluster start
6. and then start all nodes cman process within the short time :)

Reinstalling isnt always an option. If my cluster breaks I'd have to create a large outage of all my VM's while I backup .. rebuild the cluster and then restore. Right now i have 2 prox boxes that refuse to speak with one another. Its very annoying I dont even know the cause of the disconnect I just woke up one morning and they were broken. 


Is there a detailed set of instructions on how to deal with these issues without having to reinstall ? I see you touched on some instructions but once i delete the cluster.conf will I be able to rebuild the customer like i would have in prox 1x ?

You can force quorum ('pvecm expected X'), or restart in local mode. Then you
can modify cluster.conf (or delete it).

But the suggested way is to reinstall.
