- conductor 9y agoHAMMER does support replication but it doesn't have erasure coding. If you are using a recent Linux Kernel I can suggest you to use dm-integrity [0] (optionally with dm-crypt) with your favorite filesystem. It's not erasure coding but it can help detecting silent data corruption on the disk. [0] https://old.lwn.net/Articles/721738/ https://old.lwn.net/Articles/721738/
- Veratyr 9y agoHmm, it does seem like it should be possible to put mdadm on top of dm-integrity devices, I might try that out.
