Skydick

skydick is the multi-user data-pool and monitoring host at 10.0.1.1.

Services

Data pool (SMB / NFS / iSCSI)

The full user guide and admin runbook live in DATAPOOL.md.

That document covers:

• what users need before they can use the pool
• what admins must provision for LDAP, ZFS, NFS, and SMB
• one-time SMB bootstrap versus normal LDAP password changes
• share paths for SMB and NFS
• per-user dataset layout
• verification and troubleshooting

InfluxDB (fleet monitoring)

InfluxDB v2 runs as a native NixOS service (services.influxdb2), declared in
modules/influxdb.nix. It stores time-series data for the entire fleet.

• Data path: /var/lib/influxdb2 → bind-mounted from ZFS dataset dick/system/influxdb
  (recordsize=128K, zstd compression, 500G quota)
• API: http://10.0.1.1:8086
• Organization: door1
• Buckets: door1 (door1 host + iDRAC + IoT sensors), skydick (skydick host metrics)
• Retention: infinite (ZFS handles the storage)
• Auth: operator token in agenix (secrets/influxdb-token.age), same token
  used by Telegraf on both skydick and door1
• InfluxQL v1 compat: enabled via DBRP mapping (door1 database → door1 bucket),
  used by Grafana dashboards that predate the Flux migration

ZFS dataset

# Created once (already done):
zfs create -o recordsize=128K -o mountpoint=/srv/system/influxdb \
  -o quota=500G dick/system/influxdb
chown influxdb:influxdb /srv/system/influxdb

# Check:
zfs list -o name,used,avail,compressratio dick/system/influxdb

Grafana connection

Grafana runs on door1 (Docker) and queries skydick over 10GbE. Three datasources:

Telegraf

Declared in modules/monitoring.nix. Collects host metrics and writes to the
local InfluxDB. The influxUrl option defaults to http://10.0.1.1:8086 but
skydick overrides it to http://127.0.0.1:8086 for local writes.
