# mergerfs

6 Hacker News commenters recommended mergerfs and 1 criticized it, November 2025 to November 2026. It was recommended in 5 of 13 months.

**Verdict:** Pools separate disks into one mount point, often with SnapRAID; people praise its flexibility and low maintenance. Caveat: it fights you if you want explicit disk placement.
