Storage
EasyNAS storage is built on Btrfs: pools span disks with a chosen RAID profile, and volumes (Btrfs subvolumes) are the units you share, snapshot, and quota.
Disks
Storage → Disk lists every drive with model, capacity, and status:
- System — the disk EasyNAS runs from (protected)
- Used — part of a filesystem
- Free — available for a new filesystem
- Failed — SMART problems detected
Disk health (SMART self-test results and Btrfs error counters) is surfaced on the dashboard.
File systems (pools)
Storage → File System → Create:
| Option | Choices | Notes |
|---|---|---|
| Disks | 1..n free disks | |
| RAID profile | JBOD (single), RAID 0, 1, 10, 5, 6 | RAID 5/6 require 3/4+ disks |
| Compression | none, fast (lzo), better (zlib) | transparent, per-pool |
| Mount options | read-write / read-only |
Existing pools can be mounted/unmounted, renamed, grown by adding devices, and monitored (usage, health, degraded-array warnings).
Volumes
Storage → Volume manages subvolumes on a pool: create, delete, set the owner (user/group), and take snapshots.
Where your data lives
Pools are mounted under /mnt/<pool> and volumes at /mnt/<pool>/<volume> — these
are the paths sharing protocols export.
