Host006

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.

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.

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.

• Cluster: klynge001
• Local node IP: 10.10.50.26
• Quorum: yes
• Observed members: 10.10.50.26 and 10.10.50.27

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

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.

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.

• 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.

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

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"
