# Local Proxmox VE Test Cluster — CLUSTER-INFO

Disposable, nested (libvirt/KVM) Proxmox VE lab on a Fedora workstation, used to
|
||
|
|
test software that drives a Proxmox cluster. Managed by the scripts in this
|
||
|
|
\`pve-lab/\` directory (see \`README.md\`).
|
||
|
|
|
||
|
|
## Nodes
|
||
|
|
| Role | Name | IP | Web UI |
|
||
|
|
|------|------|----|--------|
|
||
|
|
| PVE node 1 | ${PVE1_NAME} | ${PVE1_IP} | https://${PVE1_IP}:8006 |
|
||
|
|
| PVE node 2 | ${PVE2_NAME} | ${PVE2_IP} | https://${PVE2_IP}:8006 |
|
||
|
|
| Storage (NFS + iSCSI) | ${STORE_NAME} | ${STORE_IP} | (Debian; no web UI) |
|
||
|
|
|
||
|
|
Cluster: **${CLUSTER_NAME}** · Domain: **${DOMAIN}** · Network: ${NET_SUBNET}/${NET_PREFIX} (gw ${NET_GW})
|
||
|
|
|
||
|
|
## Credentials
|
||
|
|
- **Root password** (all PVE nodes + storage VM): \`${ROOT_PASSWORD}\`
|
||
|
|
- **SSH key** (passwordless root everywhere): \`${SSH_KEY}\`
|
||
|
|
- Fingerprint: ${fp}
|
||
|
|
- SSH from this host — \`IdentitiesOnly=yes\` is **required** (otherwise the agent's
|
||
|
|
keys exhaust the server's MaxAuthTries before the lab key is offered):
|
||
|
|
\`\`\`bash
|
||
|
|
ssh -i ${SSH_KEY} -o IdentitiesOnly=yes root@${PVE1_IP}
|
||
|
|
# or, from pve-lab/: source lab.env && lab_ssh ${PVE1_IP} pvecm status
|
||
|
|
\`\`\`
|
||
|
|
|
||
|
|
## Shared storage (visible on both nodes)
|
||
|
|
- **lab-nfs** — NFS from \`${STORE_IP}:/srv/nfs\` (content: images, iso, vztmpl, backup, rootdir)
|
||
|
|
- **lab-lvm** — shared LVM volume group \`pve_shared\` on the iSCSI LUN
|
||
|
|
- Storage VM iSCSI target: \`${ISCSI_IQN}\` (portal ${STORE_IP}:3260)
|
||
|
|
|
||
|
