NS_I_REBUILD_DISK
NS_I_REBUILD_DISK — 0x400D005F
Treat this code as a record of administrator-triggered disk rebuild: in the operation that returned it, an administrator explicitly requested reconstruction of a content disk.
The contract behind the code
Rebuild events form a stateful sequence with one owner, an initial disk condition, reconstruction sources, progress, and a terminal result. In the context of administrator-triggered disk rebuild, preserve the entire sequence and the pre-rebuild identity data; repeated starts can destroy the evidence that distinguishes source loss from destination failure. Locate the first component changing state in this condition and distinguish later summary errors.
Important boundary. This event confirms the command was issued, not that reconstruction started safely or completed successfully. Record the exact constant and returning API.
Diagnostic worksheet
| Record before retry | Use in verification |
|---|---|
| Administrator source, disk identity, reason, and pre-request disk state | Ties the message to one server object and one transition instead of a later retry. |
| Available rebuild sources, free capacity, control-block version, and filesystem health | Separates configuration or identity from storage, parser, network, or lifecycle state. |
| Whether a rebuild was already active or the disk was serving content | Provides a stable before/after comparison for the proposed correction. |
| Subsequent started, progress, finished, or aborted events | Shows whether the status is expected information, a warning, or the first failure in the event sequence. |
Preserve the smallest reproducible evidence set and redact client content, credentials, and private network details before sharing it.
Useful comparisons
- Validate the disk identity and source set before issuing the request in a test environment. Retain a known-good stream, session, or server object so a broad restart is not mistaken for repair of the reported failure.
- Compare an operator request with an automatically initiated rebuild. Record the first server event, object state, or return value that changes.
- Ensure a duplicate request does not create concurrent rebuild owners. Keep media bytes, server identity, and unrelated publishing-point settings fixed.
Do not use repeated reconnects as the main test; a later success can belong to a new session, publishing-point generation, server owner, completed background operation, or different media path.
Read the result in context
| Observed comparison | Interpretation |
|---|---|
| A known-good object succeeds through the same component | The platform path exists; concentrate on the production object, identity, metadata, or state captured above. |
| The control fails at the same first operation | Preserve server, storage, plug-in, topology, and network evidence before modifying media or publishing-point data. |
| The status changes after one deliberate adjustment | The diagnostic boundary moved; the replacement status now describes the next contract to investigate. |
A defensible fix
Correction: Remove the root storage or metadata problem, then initiate a single supported rebuild with enough source data and capacity. Keep the original server configuration, event sequence, object inventory, input hash, and topology snapshot so the change can be reversed and explained.
Accept the repair only when the command produces one rebuild sequence ending in completion and post-rebuild validation. Repeat the original supported operation under the original identity and object state; a simplified media file, replacement server, new session, or different client is useful comparison evidence but not final regression proof.
