Operational Knowledge Base (auto-updated)

PVE Node Quick Reference

• nl-pve01 (94GB, ZFS): Chronically oversubscribed (80% RAM, 7 VMs + 57 LXC). No swap. CHECK FIRST on multi-host NL alert bursts.
• nl-pve02 (16GB, ext4/LVM): VM-based. 8GB swap, swappiness=10. Healthy.
• nl-pve03 (125GB, ZFS): No swap. High RAM (86%). CGC LXC here (8GB).
• gr-pve01 (94GB, ZFS): 8GB swapfile on NVMe, swappiness=10. 83% RAM.
• gr-pve02 (31GB): GR iSCSI server. ZFS ssd-pool RAID1, LIO targetcli, 15 targets, VLAN 188. SeaweedFS migrated to NFS on sdc.

IoT Pacemaker Cluster (NL)

• 3-node: nlcl01iot01 (VMID 666), nl-iot02, nlcl01iotarb01
• Resources: HA, Mosquitto, Zigbee2MQTT, ESPHome, Node-RED (group failover)
• On failure: Pacemaker fences and migrates. DO NOT failback automatically.
• SSH: ssh -i ~/.ssh/one_key root@nlcl01iotXX
