Proxmox 2.1 setup notes

In addition to the web interface setting (for the cluster), need to configure aptitude as well. Add to somewhere appropriate (e.g. /etc/apt/apt.conf.d/70debconf)

Acquire::http::Proxy "http://wwwcache.gla.ac.uk:8080";
Acquire::ftp::Proxy "http://wwwcache.gla.ac.uk:8080";

Have to set up NTP on each system as before. Edit /etc/ntp.conf to add:

server login.physics.gla.ac.uk iburst

and restart the service

/etc/init.d/ntp restart

Check with ntpq -p, output will look something like:

     remote           refid      st t when poll reach   delay   offset  jitter

Time needs to be reasonably accurate before attempting cluster join!

Instructions at http://pve.proxmox.com/wiki/Proxmox_VE_2.0_Cluster

Login to the a node. To create cluster:

pvecm create YOUR-CLUSTER-NAME

Use a unique name. This name cannot be changed later!

To check the state of cluster:

pvecm status

To add a node, log in to that node and run:

pvecm add IP-ADDRESS-CLUSTER

Where the address is that of one of the existing cluster nodes. It will ask for the root password of the node you are connecting to.

Remember to add the new node's address to nfs shares etc.
