STATUS_VOLMGR_NO_VALID_LOG_COPIES
None of the pack metadata log copies can be accepted as valid
STATUS_VOLMGR_NO_VALID_LOG_COPIES is an LDM metadata failure. Dynamic disks maintain a database describing volume types, offsets, memberships, and related configuration, and Microsoft documents that this configuration is replicated across dynamic disks.
The error says the pack has no valid log copies, so recovery cannot simply choose another healthy replica. Linux kernel documentation independently describes the Windows LDM format as a journalled database, which helps explain why a log-copy validity failure is distinct from an ordinary file-system error inside a volume.
Preserve all pack disks before attempting destructive repair. Compare which disks are readable and whether their LDM regions can be examined; a single missing drive may matter if the remaining replicas are also corrupted or incomplete.
What to inspect
- Collect System and storage events for the time when the pack configuration became unreadable or inconsistent.
- Keep every available dynamic disk from the pack together so metadata copies can be compared during recovery.
- For forensic inspection, use read-only tools or disk images before initializing, cleaning, or converting the affected disks.
