Storage Layout

Overview
Centerpoint uses a three-tier storage strategy:
Local NVMe — fast system and application data storage
Ceph OSD block devices — two NVMe drives contributing to a distributed Ceph
cluster for object/block storage across the homelab
NFS mounts from UnRAID — bulk media and data storage from the NAS server at
192.168.1.119
Local NVMe Drives
System Drive — 
nvme1n1 (1.8 TB)
The primary system disk, GPT-partitioned with LVM.

1.8 TB
/
Root filesystem
Current usage: 520 GB used / 1.3 TB free
This drive holds the OS, all Docker image layers (
/var/lib/docker), container
volumes, and the compose project files under 
/home/jeeves/docker/.
Ceph OSD — 
nvme0n1 (931.5 GB)
Configured as a Ceph OSD block device under LVM management.
Mounted at 
/media/jeeves/1TB_Vol2.
The volume appears nearly empty at the filesystem level because Ceph manages the
block device directly — actual utilised capacity is tracked by the Ceph cluster,
not the OS mount point.
Ceph OSD — 
nvme2n1 (931.5 GB)
Second Ceph OSD block device, LVM-managed.
Mounted at 
/media/jeeves/1TB_Vol1. Shows ~115 GB used at the OS level; the
remainder is managed by Ceph.
Both Ceph OSD drives contribute to a distributed storage pool shared across the
homelab. Ceph provides replication and data protection at the cluster level rather
than at the individual host level.
NFS Mounts — UnRAID (
192.168.1.119)
UnRAID at 
192.168.1.119 hosts a 38 TB storage pool (~32 TB in use) and exports
three NFS shares, auto-mounted on Centerpoint at boot.

These paths are bind-mounted into media containers — the media files themselves
are never stored locally on Centerpoint.
Notes / Gotchas
If UnRAID is offline or rebooting, NFS mounts will stall and any container with
a bind mount into 
/mnt/* will hang or fail to start until the mount recovers.
Docker named volumes (databases, config state, etc.) all reside on the system
NVMe under 
/var/lib/docker/volumes/ — these are not automatically backed up
to UnRAID.
The Ceph cluster should be monitored independently; degraded OSD status does not
surface through Docker or the OS mounts in any obvious way.
