mergerfs is a FUSE-based union filesystem that logically merges multiple filesystem paths into a single mount point. It offers configurable file placement policies, hard link support, xattrs, and POSIX ACLs for managing storage across many commodity drives.
Use cases
- merge multiple hard drives into one mount point
- pool JBOD disks without RAID
- combine filesystems for a Plex or Jellyfin media library
- add or remove drives from a pooled storage volume
- present a single directory view over scattered data paths
When to choose
- you want to pool disks of different sizes and filesystem types without RAID
- you need runtime-configurable file placement policies
- you want near-native IO passthrough performance
- you run a home media server on heterogeneous storage
When to avoid
- you need redundancy or parity protection (use SnapRAID or RAID)
- you need read/write overlay with whiteouts like OverlayFS
- you need files split/striped across devices
- you are on a non-Linux platform without FUSE support
