FsRtlBalanceReads function (ntifs.h)
The FsRtlBalanceReads routine signals to a fault-tolerant disk driver that it is now safe to start balancing reads from a mirrored drive.
Syntax
NTSTATUS FsRtlBalanceReads(
[in] PDEVICE_OBJECT TargetDevice
);
Parameters
[in] TargetDevice
A pointer to the device object from which the device starts the balanced read.
Return value
FsRtlBalanceReads returns STATUS_INVALID_DEVICE_REQUEST if the device is not a mirror.
Remarks
FsRtlBalanceReads signals to a fault-tolerant disk driver that it is safe to start balancing reads from a mirrored drive. A file system typically calls FsRtlBalanceReads for a newly mounted volume once it has determined that the volume is clean.
