ERROR_QUERY_STORAGE_ERROR
Locate the rejected storage invariant: query storage error
ERROR_QUERY_STORAGE_ERROR (0x803A0001) is emitted by the storage path when the storage provider returned a subsystem-specific failure while answering a management query, so the outer HRESULT lacks the lower-level provider detail while diagnosing this result. The deciding object for it is Windows Storage Management provider request and returned extended status, so the first investigation belongs there rather than in a generic “disk failure” bucket.
Windows Storage Management providers can return an outer management HRESULT plus a more precise extended error while diagnosing this result. The extended provider status, target object identity and correlated storage event are the useful evidence when the outer query result is generic. This object model determines which identifiers, counts and ownership state are meaningful while diagnosing it.
A useful record contains more than the final UI symptom: retain the first failing call, target identity, topology and state transition before management software rescans the disks.
Evidence to preserve before repair
| Storage diagnostic field | Value |
|---|---|
| Owning object | Windows Storage Management provider request and returned extended status |
| Rejected invariant | the storage provider returned a subsystem-specific failure while answering a management query, so the outer HRESULT lacks the lower-level provider detail |
| Identity and generation | storage subsystem UniqueId, provider name and version, original CIM/API operation, extended error object, target object IDs and correlated storage events |
| Narrow experiment | repeat the same query directly against the provider, capture its extended error object, and compare it with a query for a known healthy storage object |
| Closest comparison | ERROR_VOLMGR_STRUCTURE_SIZE_INVALID |
Do not overwrite this result with a close, detach or rollback error. Preserve the causal order so the original storage contract remains visible.
One-variable reproduction
- Before changing state for it, freeze the failing generation and save storage subsystem UniqueId, provider name and version, original CIM/API operation, extended error object, target object IDs and correlated storage events.
- Exercise this exact comparison for it: repeat the same query directly against the provider, capture its extended error object, and compare it with a query for a known healthy storage object for it.
- During the result comparison, keep image bytes, unrelated disks, provider policy and cluster topology fixed.
- After the test, record the next return value and the durable object state; crossing the boundary should expose a later result rather than silently retrying while diagnosing this result.
A useful diagnostic fork is ERROR_VOLMGR_STRUCTURE_SIZE_INVALID versus it. This code concerns the storage provider returned a subsystem-specific failure while answering a management query, so the outer HRESULT lacks the lower-level provider detail; the alternate code should remain observable after the fix, proving the application did not suppress the entire subsystem while diagnosing it.
Mechanism-specific note
The outer management layer has intentionally collapsed a provider-specific failure for it. Retrieve the extended error object, provider return code and target UniqueId in the same call context. Without that information, retries and remediation are guesses because hardware, clustering and software providers can all surface this wrapper.
Repair without rewriting unrelated metadata
Retrieve the provider-specific extended error, repair that concrete subsystem condition and rerun the original storage query without suppressing the lower-level status while diagnosing it. Apply the change through the supported storage API, then close and reacquire affected objects before retrying.
- The original request now reaches success or a documented later status with the intended layout and access mode while diagnosing it.
- A new enumeration reports internally consistent IDs, counts, geometry and ownership for the object corrected after it.
- The passing state survives the lifecycle transition relevant to it, such as reopen, remount, owner change or detach/attach for it.
- The application still distinguishes it from
ERROR_VOLMGR_STRUCTURE_SIZE_INVALIDand has no unbounded retry loop.
A reboot, blanket disk conversion or deletion of storage metadata is not a justified first response to it; it changes multiple invariants and can erase the evidence needed to identify the defect.
