ERROR_VOLMGR_NO_VALID_LOG_COPIES
Interpret the state transition: volmgr no valid log copies
ERROR_VOLMGR_NO_VALID_LOG_COPIES has unsigned value 0xC0380058. In the volmgr layer, it rejects a specific contract because no disk in the pack contains a configuration-log copy that passes sequence and integrity checks for it. Diagnosis of this result should follow dynamic-disk pack identity, quorum and replicated configuration log through one controlled state transition.
Dynamic volumes are represented as packs containing disks and volumes; each volume has one or more plexes, and each plex is assembled from members and extents. Indices and counts are relative to the submitted layout generation, while configuration logs are replicated across participating dynamic disks for it. This object model determines which identifiers, counts and ownership state are meaningful.
Keep the first result attached to its request parameters and object generation. Cleanup failures or a later drive-letter change are secondary evidence, not replacements for the original boundary while diagnosing this result.
Record geometry, identity and ownership
| Storage diagnostic field | Value |
|---|---|
| Closest comparison | ERROR_VOLMGR_PACK_HAS_QUORUM |
| Owning object | dynamic-disk pack identity, quorum and replicated configuration log |
| Rejected invariant | no disk in the pack contains a configuration-log copy that passes sequence and integrity checks |
| Identity and generation | pack GUID and name, online state, primary flag, disk inventory, configuration-log sequence numbers, quorum view and failing transaction ID |
| Narrow experiment | enumerate configuration-log copies and sequence numbers, restore one healthy writable disk in a lab pack, and repeat the commit |
Keep this HRESULT as the primary result if rollback or cleanup reports another code; those later values describe recovery, not the first rejected invariant while diagnosing this result.
Separate validation from capability
- serialize the failing request and the enumeration from which its identifiers came.
- Preserve pack GUID and name, online state, primary flag, disk inventory, configuration-log sequence numbers, quorum view and failing transaction ID while every handle is still valid.
- Repeat the operation using this controlled change: enumerate configuration-log copies and sequence numbers, restore one healthy writable disk in a lab pack, and repeat the commit.
- Close and reacquire the relevant objects, then run once more to test lifecycle correctness after this result.
A useful diagnostic fork is ERROR_VOLMGR_PACK_HAS_QUORUM versus it. This code concerns no disk in the pack contains a configuration-log copy that passes sequence and integrity checks; the alternate code should remain observable after the fix, proving the application did not suppress the entire subsystem.
Mechanism-specific note
Dynamic-disk configuration is replicated, and sequence plus integrity decide which copy is authoritative. Inventory every participating disk and record the newest readable sequence before repair while diagnosing it. Sector-level edits or copying a log from another pack can destroy the GUID and generation relationships that allow supported recovery to select a consistent configuration.
Verification after correction
Repair the pack configuration through supported dynamic-disk management, preserving GUIDs and the newest valid log sequence; avoid sector-level edits to replicated metadata for it. Apply the change through the supported storage API, then close and reacquire affected objects before retrying.
- The controlled A/B case changes only the invariant responsible for it.
- No unrelated disk, cluster owner, tier policy or virtual-disk backing file is altered to hide it.
- Health, synchronization or job state reaches a terminal value consistent with the repaired the operation.
- Telemetry includes both symbolic names when it or
ERROR_VOLMGR_PACK_HAS_QUORUMoccurs again.
Before responding to it with destructive cleanup, prove which object owns the failure. Changing every disk or provider at once prevents a meaningful regression test.
