Node menu reference

Select a node in the tree and the content panel offers the settings for that one server. Where the Datacenter menu decides how the system behaves, this menu decides how one machine is configured.

Every node panel keeps three buttons in its toolbar: Reboot, Shutdown and Shell.

Reboot and Shutdown act on the server, not on a machine

They stop the node and everything running on it. In a cluster, move running machines elsewhere first — Bulk Actions → Bulk Migrate does this in one step.

Shell opens a terminal session on the server. Nothing in this documentation asks you to use it; VM2Cloud support may, while helping with a problem.

Search

The same resource list as Datacenter → Search, narrowed to this node.

Summary

Status and time-series graphs for the server itself: CPU, memory, disk, network and load. Use the period selector above the graphs to widen the window, and Maximum / Average to switch how each point is calculated — averages hide short spikes that maximums reveal.

Package versions lists the installed components and their versions. Have this open when you contact support.

Notes

A free-text note about this server specifically — which rack, which power feed, which switch ports, anything the next person will want. Separate from the datacenter-wide note.

System

Entry	What it holds
Network	Bridges, bonds and VLANs — see Node network configuration
Certificates	The certificates this node presents — see Certificates
DNS	Search domain and name servers
Hosts	Static name-to-address entries for this node
Options	Node-level settings, some inherited from the datacenter
Time	Time zone, and the current server time
System Log	The server’s log, live or over a chosen period

DNS

Search domain and up to three name servers. Edit to change them.

Hosts

Static name-to-address entries, including the node’s own name.

Cluster members must be able to resolve each other

If there is no reliable DNS on the management network, each node’s entries here are what makes joining and staying in a cluster work. A node that installs perfectly and then cannot join is very often a name that does not resolve.

Options

Setting	What it does
Location	Geographic label. Reads from Datacenter options until overridden here.
Start on boot delay	How long to wait after the node boots before starting machines, so storage and networking settle first.
MAC address for Wake on LAN	Lets the node be powered on remotely.
RAM usage target for ballooning	How much of the host’s memory to keep in use before reclaiming memory from machines that allow it.

Time

Shows the time zone and the live server clock. Edit changes the time zone.

The clock itself is kept synchronised automatically; there is no setting for it here.

Clock drift breaks cluster sign-in

Nodes whose clocks disagree reject each other’s sessions. If this panel shows a node’s time noticeably out of step with the others, see Fixing “Authentication failed! (401)”.

System Log

The server’s log. Live Mode follows it as it happens; Select Timespan jumps to a window around a known incident.

This is the system log. Output from a specific action is under Task History, and blocked network traffic is under Firewall → Log.

Updates

Available updates for this node, with Refresh to check, Changelog to see what an update contains, and Upgrade to apply.

Entry	What it holds
Repositories	Which update sources this node uses
Update Bundles	Offline updates, uploaded rather than downloaded

Before you apply updates to a production node, contact VM2Cloud support to confirm the right update path for your release.

Firewall

This node’s own rules, plus Options for the node-level switches and Log for traffic the firewall acted on.

See Firewall.

Disks

The physical disks in this server and their health, plus the entries that turn them into usable storage: LVM, LVM-Thin, Directory and ZFS.

See Disks and local storage.

Ceph

This node’s part of hyper-converged storage — its configuration, monitors, OSDs, shared filesystem and pools. Present only once Ceph is installed.

Replication

Replication jobs that involve this node, with Log for a job’s last run and Schedule now to run one immediately.

See Replication.

Task History

Everything that has run on this node, with who ran it, when, and whether it succeeded.

• View Task opens the full output of one task.
• Download saves it — do this before contacting support.
• Filter narrows by type, user or status.

Subscription

The licence state of this node.

Button	What it does
Download License Request	Produces the file identifying this node, for the licensing portal
Upload License	Installs the licence file the portal returns
Check	Re-validates the installed licence
Remove Subscription	Removes the licence from this node
System Report	Generates a diagnostic bundle for support

What a licence gates

A node needs an active licence, or a trial that has not run out, to create, clone, import or reconfigure machines (including resizing or moving their disks), restore a backup as a new machine, set up or run replication, or join a cluster. Setting up Ceph storage and adding a machine to high availability each need a licence that covers that feature. Running machines are never affected by licence state: you can always start, stop, snapshot and back up the machines you have, and restore a backup over the machine it was taken from.
