Hardware-offloaded erasure coding with DOCA Erasure Coding (Reed-Solomon, doca_ec) on a BlueField DPU, ConnectX NIC, or host: generating parity for data blocks, rebuilding lost blocks from the survivors, and refreshing parity after a change. Trigger on "one data block changed, how do I refresh parity without re-encoding", "a disk failed and 2 parity blocks are gone, can I rebuild", "RAID-6 resilience across 12 disks", "my doca_ec_task_create returns NOT_PERMITTED", or…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# DOCA Erasure Coding ## Examples - **"A disk failed; can I rebuild from parity?"** — this is in scope if the layout is Reed-Solomon N+K. Query `doca_ec_cap_*` before sizing recover. - **"One data block changed; refresh parity without re-encoding."** — use the update task. Do not route this to replication or network FEC. ## Quick answer: capability check and sample choice Before writing code, query the device: `doca_ec_cap_task_create_is_supported`, `doca_ec_cap_task_update_is_supported` or `doca_ec_cap_task_recover_is_supported` for the task you need, then `doca_ec_cap_get_max_block_size` and `doca_ec_cap_get_max_buf_list_len` to size blocks. Start from the shipped sample for that task under `/opt/mellanox/doca/samples/doca_erasure_coding/` (copy it; never edit the installed one). Use the update task to refresh parity for a changed block instead of re-encoding everything. ## Instructions Follow Loading order below. Open the tasks companion for configure / recover / debug. Open the capabilities companion for create / recover / update and matrix policy. Do not open every companion file. **Where to start:** This skill assumes DOCA is already installed and …

How to install
mdr add nvidia/skills/doca-erasure-coding@sha256:1d2bca11e4580b70The line at the top of this page pins the label git:20261022.a4cf47e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
