ERROR_LOG_RESIZE_INVALID_SIZE
A TxF resource-manager log resize request violates the accepted sizing parameters
ERROR_LOG_RESIZE_INVALID_SIZE is a Transactional NTFS (TxF) file-system status. TxF resource managers use logging for transactional recovery. The TxF control interface exposes FSCTL_TXFS_MODIFY_RM and the TXFS_MODIFY_RM structure to change log parameters for a secondary resource manager and to specify growth or container settings. This error means the requested log size itself is unacceptable for the resource manager; it is not the same as a later failure to allocate disk space for valid log growth.
Capture the complete TXFS_MODIFY_RM structure and its flags before DeviceIoControl is issued. Check whether size fields are being interpreted as bytes, containers, or percentages according to the selected flags and whether mutually exclusive growth modes were combined. Query the RM state first so the requested value can be compared with its current configuration. Do not diagnose this as generic CLFS corruption unless separate log-sector or metadata errors are also present.
What to inspect
- Log the TXFS_MODIFY_RM flags and every sizing field exactly as submitted.
- Verify that growth increment units match the flag selecting containers or percentage.
- Use FSCTL_TXFS_QUERY_RM_INFORMATION to compare the requested change with current RM state.
