BSD Distributions & High-Security/Storage Networking
DragonFly BSD and Hammer2
Hammer2 is DragonFly BSD's clustered filesystem, designed around crash resilience, snapshots, and multi-master replication. It stores metadata in a way that supports fast recovery and consistent replication across nodes. The trade-off is a small community and limited production tooling compared with ZFS.
ประเด็นสำคัญ
- Evaluate cluster replication behavior with realistic latency between nodes.
- Test crash recovery by cutting power during writes, not just during idle operation.
- Plan snapshot retention and pruning from the start, since snapshots consume space.
- Benchmark small-file and metadata-heavy workloads, which stress filesystems differently than streaming I/O.
- Confirm backup tooling understands Hammer2 snapshots and replication state.
- Keep a tested restore procedure independent of the cluster.
- Monitor replication lag and divergence as first-class alerts.
- Accept the support risk and document exit paths before production use.
คำถามที่พบบ่อย
Is Hammer2 ready for production?
It is used in production by some teams, but the community and tooling are much smaller than ZFS.
How does it compare with ZFS?
Hammer2 emphasizes clustering and crash recovery. ZFS has broader adoption, tooling, and features.
Does replication require identical hardware?
No, but capacity and performance should be comparable to avoid lag.
What is the biggest risk?
Limited ecosystem support if something goes wrong under pressure.
