FRS_ERR_SYSVOL_IS_BUSY
The file replication service cannot process the request. The system volume is busy with a previous request.
FRS_ERR_SYSVOL_IS_BUSY is Win32 error 8015 (0x00001F4F) in legacy File Replication Service (FRS).
What to verify
Verify whether no earlier SYSVOL promotion, population, demotion, or recovery request is still active. Check current SYSVOL operation and owner, start time and progress events, and management request IDs.
Likely causes
- a previous request is still processing.
- an administration tool submitted duplicate operations.
- the service is completing recovery.
- state cleanup after timeout has not finished.
Troubleshooting steps
- Collect current SYSVOL operation and owner.
- Record start time and progress events.
- Correlate management request IDs with the File Replication Service event log, Service Control Manager, Directory Service and Netlogon events, RPC diagnostics, and replica-set state.
Handling, retry, and recovery
Wait for or diagnose the existing operation, query final state, and do not force a second conflicting SYSVOL transition.
Related errors
FRS_ERR_INVALID_API_SEQUENCE indicates a bad call order; this code reports a valid request blocked by an already active SYSVOL operation
Example
An automation job times out locally and submits the same populate request again. Tracking the original operation shows it is still active, so the duplicate request is suppressed.
