Proxmox VE Operations Reference (Release 9.1.2)

1. Cluster Configuration (Auto-Detect)

2. Cluster Requirements

2.1 Port Requirements

2.2 General Requirements

• Time sync -- All nodes must have synchronized clocks. Verify: timedatectl status. Use chrony or systemd-timesyncd. Drift causes auth and replication failures.
• Network latency -- Corosync requires <5 ms (LAN). Above 10 ms unreliable for >3 nodes. Dedicated physical NIC recommended.
• Corosync links -- Up to 8 redundant links (link0..link7). Each on separate physical network. Priority-based failover: --link0 IP,priority=15 --link1 IP,priority=20.
• CPU compatibility -- Online migration requires same vendor (Intel-to-Intel, AMD-to-AMD). Cross-vendor not guaranteed.
• Hostname/IP -- Cannot be changed after cluster creation. Use IP addresses in cluster config to avoid DNS issues.

3. Cluster Creation & Management

# Create cluster (optionally with dedicated network)
pvecm create CLUSTERNAME
pvecm create CLUSTERNAME --link0 10.10.10.1

# Get join information (run on existing node)
pvecm join-info

# Join cluster (run on joining node)
pvecm add IP-ADDRESS-CLUSTER
pvecm add IP-ADDRESS-CLUSTER --link0 LOCAL-IP        # separated cluster network

# Remove node (migrate all VMs/CTs first!)
# On the node being removed:
systemctl stop pve-cluster corosync
# On a remaining node:
pvecm delnode NODENAME
rm -rf /etc/pve/nodes/NODENAME                       # clean up

# Emergency quorum override (use with extreme caution)
pvecm expected 1

# Update/regenerate node certificates
pvecm updatecerts
pvecm updatecerts --force                             # force new SSL cert
pvecm updatecerts --unmerge-known-hosts               # clean legacy SSH

4. QDevice (External Vote Support)

Provides external vote for even-node clusters (especially 2-node). Grants vote to only one partition in split-brain.

# Install (external server)
apt install corosync-qnetd

# Install (all PVE nodes)
apt install corosync-qdevice

# Setup (run on ONE PVE node)
pvecm qdevice setup <QDEVICE-IP>

# Remove
pvecm qdevice remove

# Verify
pvecm status          # look for "Qdevice" in Flags

Status flags: A = Alive, V = Voting, MW = Master Wins, NA = Not Alive, NV = Not Voting, NR = Not Registered.

Important:

• Uses TCP 5403 -- ensure firewall allows it.
• Remove QDevice before adding/removing nodes. Re-add after reaching even node count.
• Odd-node clusters: QDevice provides (N-1) votes, creating near-SPOF. Not recommended.

5. Safety Protocols

Corosync config change procedure:

cp /etc/pve/corosync.conf /etc/pve/corosync.conf.new     # 1. copy
# edit corosync.conf.new (increment config_version!)
cp /etc/pve/corosync.conf /etc/pve/corosync.conf.bak     # 2. backup current
mv /etc/pve/corosync.conf.new /etc/pve/corosync.conf     # 3. activate
systemctl status corosync                                  # 4. verify

6. Action Review Protocol

Mandatory. Perform this review before every action executed directly on a Proxmox node, VM, or container (commands, config changes, service operations).

Exception: Read-only operations — reading logs, querying status, gathering information without changing anything — are considered safe and can be performed immediately without this review.

6.1 Steelman Prompt

Consider the planned action or configuration to be executed on the Proxmox server in its ideal, most successful form. Imagine this action represents the safest, most efficient, and optimally integrated solution. Articulate how this action perfectly fulfills the goals of system administration, increases stability, and fully meets user needs.

6.2 Red-Team Prompt

Review the planned Proxmox action as if you were an experienced admin or security analyst seeking to uncover potential risks. Identify possible weaknesses in the configuration, consider outage risks, data loss, or unintended side effects. Test the robustness of the plan under worst-case scenarios to ensure it remains safe and reliable even under pressure.

6.3 Decision

At the end of the red-team review, assess whether the identified risks or weaknesses are severe enough to stop the planned action. If the action appears safe, logical, and robust, it can be executed immediately. If significant uncertainties remain, the user must be explicitly asked for confirmation. Conclude with a clear decision: either "Execute action" or "Ask user for confirmation".

  --compress zstd                                          # all guests
vzdump --pool mypool --storage {storage} --mode snapshot   # by pool
vzdump --all --exclude 100,200 --storage {storage}         # exclude guests
vzdump --stop                                              # stop running jobs

9.2 Backup Options

9.3 Scheduled Backups

• Configure: Datacenter > Backup or /etc/pve/jobs.cfg
• Schedule format: Calendar events (sat 02:00, */6:00, mon..fri 22:00)
• Managed by pvescheduler daemon
• Repeat missed: Runs skipped jobs after host was offline

9.4 Restore

# Restore VM

pct restore {vmid} {backup_file} --storage {target_storage}

# Inspect backup without restoring
pvesm extractconfig {backup_volume}

9.5 Backup Encryption

Only with PBS storage:

pvesm set {pbs_storage} --encryption-key autogen           # auto-generate key

File naming: vzdump-{type}-{vmid}-{YYYY_MM_DD-HH_MM_SS}.{ext} (type: qemu or lxc)

10. Storage Replication (pvesr)

Replicates guest volumes via ZFS snapshots to another node. Reduces migration time and adds redundancy for local storage. Supported storage: ZFS (local) only.

pvesr create-local-job {vmid}-0 {target_node} \
  --schedule "*/15" --rate 10                              # create (every 15m, 10 MBps)
pvesr list                                                 # list jobs
pvesr status                                               # job status
pvesr disable {vmid}-0                                     # disable
pvesr enable {vmid}-0                                      # enable
pvesr update {vmid}-0 --schedule "*/5"                     # change schedule
pvesr delete {vmid}-0                                      # delete

Schedule examples: */15 (every 15 min), */00 (hourly), 1:00 (daily at 1am)

Replication network:

# /etc/pve/datacenter.cfg
replication: secure,network=10.1.2.0/24

Behavior:

• Failed jobs retry every 30 minutes automatically.
• Migration to replication target = fast (delta sync only). Direction auto-reverses.
• HA + replication: supported, but potential data loss between last sync and failure.

11. High Availability (ha-manager)

11.1 Status & Resources

ha-manager status                                          # HA status
ha-manager status --verbose                                # + full CRM/LRM JSON
ha-manager config                                          # list all HA resources
ha-manager config --type vm                                # VMs only
ha-manager config --type ct                                # CTs only

11.2 Manage Resources

ha-manager add vm:{vmid} --state started \
  --max_restart 3 --max_relocate 2                         # add VM
ha-manager add ct:{vmid} --state started                   # add CT
ha-manager remove vm:{vmid}                                # remove
ha-manager set vm:{vmid} --state started \
  --max_restart 2 --max_relocate 1                         # update
ha-manager set vm:{vmid} --failback 1                      # enable failback

Resource states: started, stopped, disabled, enabled, ignored

11.3 Migration & Maintenance

ha-manager migrate vm:{vmid} {target_node}                 # online migrate
ha-manager relocate vm:{vmid} {target_node}                # stop + start on target
ha-manager crm-command stop vm:{vmid} 120                  # stop (0 = hard stop)

ha-manager crm-command node-maintenance enable {node}      # enable maintenance
ha-manager crm-command node-maintenance disable {node}     # disable maintenance

11.4 HA Rules

# Node affinity (prefer/restrict nodes)
ha-manager rules add node-affinity myrule \
  --resources vm:100,vm:101 --nodes node1:2,node2:1 --strict 0

# Resource affinity (keep together or apart)
ha-manager rules add resource-affinity keepapart \
  --resources vm:100,vm:101 --affinity negative            # keep on separate nodes

ha-manager rules list                                      # list all rules
ha-manager rules remove {rule_id}                          # remove rule

11.5 Fencing & Logs

• Fencing: Watchdog-based (softdog or hardware). Node fences itself on quorum loss. Use hardware watchdog (IPMI) in production.
• CRM log: journalctl -u pve-ha-crm -f
• LRM log: journalctl -u pve-ha-lrm -f

15. SDN (Software-Defined Network)

Virtual zones (isolation), VNets (virtual networks), and subnets (IP ranges). Applied cluster-wide.

Zone types: simple, VLAN (802.1Q), QinQ, VXLAN (overlay), EVPN (BGP overlay)

pvesh set /cluster/sdn                                     # apply SDN changes

• After apply, VNets appear as Linux bridges on all nodes.
• IPAM: Built-in PVE, Netbox, or phpIPAM.
• DHCP: dnsmasq-based, per-subnet.
• Firewall: VNet-level rules require nftables-based proxmox-firewall.

Config files: /etc/pve/sdn/zones.cfg, /etc/pve/sdn/vnets.cfg, /etc/pve/sdn/subnets.cfg, /etc/pve/sdn/controllers.cfg

16. Network Diagnostics

# Interface status
pvesh get /nodes/{node}/network --output-format json
cat /etc/network/interfaces
cat /etc/network/interfaces.new                            # pending changes

# Apply / test
ifreload -a                                                # apply live (ifupdown2)
ifreload -a --test                                         # dry-run (ALWAYS test first)

# Bonding
ls /proc/net/bonding/ 2>/dev/null                          # list bonds
cat /proc/net/bonding/{name}                               # inspect bond

# Layer 2 / Layer 3
ip link show                                               # MTU, speed, state
bridge vlan show                                           # VLAN check
ovs-vsctl show                                             # OVS (if used)
getent hosts {hostname}                                    # DNS resolution

# Corosync
pvecm status                                               # link states
journalctl -b -u corosync                                  # corosync logs
journalctl -b -u corosync | grep -i "link\|knet"          # link debugging

Bond recommendations for corosync:

• Use dedicated physical NICs for primary link.
• active-backup is safest for bonds.
• LACP: set bond-lacp-rate fast on both node and switch (failover: 3s vs 90s default).

NIC naming: Pin scheme: net.naming-scheme=v252 in kernel cmdline. Pin specific: pve-network-interface-pinning generate --interface enp1s0 --target-name nic1.
