Host006

Purpose

host006.hackeriet.no is a Proxmox VE hypervisor in the klynge001 cluster.

For inventory details, use the NetBox/IPAM entry host006 (device ID 75). NetBox is the source of truth for device model, rack/location, cabling, IP assignments, tenant, and current inventory state.

Emergency Access

Normal access:

ssh root@host006.hackeriet.no
Proxmox web UI: https://host006.hackeriet.no:8006/ or https://10.10.50.26:8006/

Access notes:

Proxmox access requires Hackeriet VPN/internal connectivity.
The Proxmox HTTPS certificate may have issues; browser/curl certificate warnings can be expected until fixed.
If DNS or public routing is confusing, NetBox currently documents the management address as 10.10.50.26/24.

Credentials

Do not paste secrets into the wiki.

Relevant hackeriet/pass entries:

root@host006.hackeriet.no.gpg
host006-backup-age-key.gpg

Keep decrypted values out of the wiki.

Operating System

Observed over SSH on 2026-05-20:

OS: Debian GNU/Linux 12 (bookworm)
Kernel: 6.8.12-9-pve
Proxmox VE: pve-manager/8.3.5

Treat this as emergency orientation only. Live state may differ.

Cluster

Observed over SSH on 2026-05-20:

Cluster: klynge001
Local node IP: 10.10.50.26
Quorum: yes
Observed members: 10.10.50.26 and 10.10.50.27
Expected votes: 3
Total votes observed: 2

If cluster state matters during an incident, verify it live with pvecm status.

Network

NetBox and LibreNMS currently agree on the physical uplink:

NetBox interface: host006 / LAN
NetBox cable: #38
Switch: pit-sw
Switch port: GigabitEthernet0/30

Observed host-level bridges include:

vmbr50 for infra hosts / management, address 10.10.50.26/24
vmbr130 for server network / public-facing VM traffic
vmbr3 for Hackeriet wired network

Do not treat this page as the source of truth for network inventory. Use NetBox for that.

Host-Level Backups

The host has a Proxmox vzdump backup job named backup-5b87a3ab-9074.

Observed configuration on 2026-05-20:

Schedule: sun 03:00
Storage: local
Mode: snapshot
Compression: zstd
Retention: keep-last=1
Mail: failure notifications to backupmail@hackeriet.no

Recent observed failure pattern:

Some backups fail with vma_queue_write: write error - Broken pipe.
Root filesystem and local Proxmox storage were nearly full during observation.

Do not delete backups or ISOs without operator approval.

Known Issues To Check

Root filesystem pressure: / was observed at 94% used on 2026-05-20.
Local Proxmox storage: local was observed at 88.33% used on 2026-05-20.
Failed service observed: munin-node.service.
ACME renewal failures for host006.hackeriet.no were seen in Proxmox logs/config during earlier investigation.

Useful Paths

Paths commonly useful during incident response:

/etc/pve/jobs.cfg
/etc/vzdump.conf
/var/log/vzdump
/var/lib/vz/dump
/var/lib/vz/template/iso
/etc/network/interfaces
/etc/pve/nodes/host006/config

Checks During Incidents

Basic host checks:

hostname -f
pveversion
pvecm status
systemctl --failed
df -h -x tmpfs -x devtmpfs
pvesm status
ip -br addr show scope global

Backup checks:

sed -n '1,220p' /etc/pve/jobs.cfg
sed -n '1,220p' /etc/vzdump.conf
find /var/log/vzdump -maxdepth 1 -type f -printf '%TY-%Tm-%Td %TH:%TM %p\n' | sort | tail -20
find /var/lib/vz/dump -maxdepth 1 -type f -printf '%TY-%Tm-%Td %TH:%TM %10s %f\n' | sort

Service checks:

systemctl status pve-cluster pvedaemon pveproxy pvestatd pvescheduler
systemctl status pve-firewall proxmox-firewall corosync
systemctl status munin-node
journalctl -u munin-node --since "1 hour ago"
