Info

•For each callback object that is registered in the list of callback objects, call the callback object'sIVdsAdviseSink::OnNotify (Opnum 3) method by using a VDS_NOTIFICATION structure thathas the following attributes:•The objectType member is VDS_NTT_VOLUME.•The Volume member is a VDS_VOLUME_NOTIFICATION with the following attributes:•ulEvent is VDS_NF_VOLUME_MODIFY.•volumeId is the VDS_OBJECT_ID of this volume object.•If VDS_FSOF_COMPRESSION is specified and the file system being formatted supportscompression, compress the file system after formatting is complete.•Set the return code in the async object to an HRESULT indicating failure or success.•If the server tried to compress the file systems after formatting but failed, the return codeMUST be set to VDS_S_VOLUME_COMPRESS_FAILED (HRESULT of 0x00042443).•If the task completed successfully, set the percentage-completed value in the async object to100.•Set the signal state in the async object to TRUE.3.4.5.2.34.3 IVdsVolumeMF3::OfflineVolume (Opnum 5)The OfflineVolume method offlines a volume. An offline volume will fail data IO. The volume maybe opened for configuration.HRESULT OfflineVolume();This method has no parameters.Return Values: The method MUST return zero or a non-error HRESULT (as specified in [MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.When the server receives this message, it MUST put the volume into the offline state.3.4.5.2.35 IVdsVolumeShrink Methods3.4.5.2.35.1 IVdsVolumeShrink::QueryMaxReclaimableBytes (Opnum 3)The QueryMaxReclaimableBytes method retrieves the maximum number of bytes that can bereclaimed from the current volume.HRESULT QueryMaxReclaimableBytes([out] ULONGLONG* pullMaxNumberOfReclaimableBytes);pullMaxNumberOfReclaimableBytes: A pointer to a variable that, if the operation issuccessfully completed, receives the maximum number of bytes that can be reclaimed from[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011262 / 360
the current volume. This number is always a multiple of the file system cluster size, which isin turn a multiple of the disk sector size.Return Values: The method MUST return zero or a non-error HRESULT (as specified in [MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.When the server receives this message, it MUST validate the following parameter:•Verify that pullMaxNumberOfReclaimableBytes is not NULL.The server MUST set values that pullMaxNumberOfReclaimableBytes references with themaximum number of bytes that can be reclaimed from the volume and then return an HRESULTindicating failure or success.3.4.5.2.35.2 IVdsVolumeShrink::Shrink (Opnum 4)The Shrink method shrinks the volume and all plexes, and then returns the released extents. TheShrink method compacts the files toward the beginning of the volume, creating free space at theend of the volume. The Shrink method also truncates the file system, reducing its size, and thentruncates the partition or dynamic volume.HRESULT Shrink([in] ULONGLONG ullDesiredNumberOfReclaimableBytes,[in] ULONGLONG ullMinNumberOfReclaimableBytes,[out] IVdsAsync** ppAsync);ullDesiredNumberOfReclaimableBytes: The desired number of bytes to be reclaimed fromthe volume. The method SHOULD attempt to reclaim the desired number of bytes as specifiedby this parameter. If it is unable to do so, it SHOULD attempt to reclaim a size smaller thanullDesiredNumberOfReclaimableBytes but greater than or equal toullMinNumberOfReclaimableBytes. Additionally ullMinNumberOfReclaimableBytesMUST be at least 1048576 bytes (1 MB). The actual number of bytes reclaimed is always amultiple of the file system cluster size, which is in turn a multiple of the disk sector size.ullMinNumberOfReclaimableBytes: The minimum number of bytes to be reclaimed from thevolume. If the method cannot reclaim at least the minimum number of bytes as specified bythis parameter, the method MUST fail and MUST NOT reclaim any bytes.ppAsync: A pointer to an IVdsAsync interface that, if the operation is successfully completed,receives the IVdsAsync interface to monitor and control this operation. Callers MUST releasethe interface when they are done with it.Return Values: The method MUST return zero or a non-error HRESULT (as specified in [MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.When the server receives this message, it MUST validate the following parameter:•Verify that ppAsync is not NULL.•Verify that ullDesiredNumberOfReclaimableBytes is not zero.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011263 / 360
