MSFT_DfsrVolumeConfig class
This class stores the per-volume settings for each volume on the system that hosts one or more replicated folders.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

| ResetDBClone | Stops the current database export or import operation and returns the database to its previous state. |
| ResumeReplication | Resumes replication for the volume. |
Properties
The MSFT_DfsrVolumeConfig class has these properties.
-
ClusterDiskResName
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: DisplayName ("Clustered Volume Physical Disk Resource Name")
If the volume is a cluster shared volume, this property specifies the physical disk resource name.
-
-
DatabasePath
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (2600), DisplayName ("Database Path")
The full path to the database. This database contains metadata about the files and folders in the replicated folder.
-
-
IsClustered
-
-
Data type: boolean
-
Access type: Read-only
-
Qualifiers: DisplayName ("Is a clustered Volume")
This property is TRUE if the volume is a cluster shared volume; it is FALSE if it is a local volume.
-
-
LastChangeNumber
-
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: MinValue ("1"), DisplayName ("Last Change Number")
The configuration sequence number. This value is incremented each time the volume configuration changes.
-
-
LastChangeSource
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: DisplayName ("Last Change Source")
Information about the originator of the last configuration change. The originator is the name of the domain controller that provided the configuration information.
-
-
LastChangeTime
-
-
Data type: datetime
-
Access type: Read-only
-
Qualifiers: DisplayName ("Last Change Time")
The time stamp of the last configuration change.
-
-
MaxJetSessions
-
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: MinValue ("16"), DisplayName ("Maximum number of Jet Sessions")
The maximum number of concurrent Jet database sessions for this volume. Every volume has its own database, and therefore this parameter is defined per-volume.
-
-
MinNtfsJournalSizeInMb
-
-
Data type: uint32
-
Access type: Read/write
-
Qualifiers: MinValue ("4"), MaxValue ("10000"), Units ("MB"), DisplayName ("Minimum USN Journal Size in MB")
The minimum size of the journal to allocate on the volume, in megabytes. If no journal exists, the DFSR creates a new journal with the specified size; otherwise, it increases the existing journal size to this minimum size. The DFSR does not change the existing journal size if it is already larger than the new minimum size.
-
-
SerialNumber
-
-
Data type: uint64
-
Access type: Read-only
-
Qualifiers: DisplayName ("Volume Serial Number")
The volume serial number.
-
-
UsnCheckPoint
-
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: MinValue ("1"), DisplayName ("Usn Check Point")
The number of journal updates to accumulate before committing a transaction.
-
-
VolumeGuid
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: key, MaxLen (36), MinLen (36), DisplayName ("Volume GUID")
The unique volume identifier.
-
-
VolumePath
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: DisplayName ("Volume Path")
The volume path name.
This string has one of the following formats: "\\.\drive:" or "\\?\volume{GUID}".
