CLUSPROP_PARTITION_INFO

The CLUSPROP_PARTITION_INFO structure contains information relevant to storage class resources that is used in a value list and consists of:

• A CLUSPROP_VALUE structure describing the format, type, and length of the partition information.
• A CLUS_PARTITION_INFO structure.

An example of a storage class resource is the Physical Disk resource. To promote clarity, the individual members of these two structures are included in the CLUSPROP_PARTITION_INFO definition.

The CLUSPROP_PARTITION_INFO structure is defined in CLUSAPI.H.

typedef struct _CLUSPROP_PARTITION_INFO {
    CLUSPROP_SYNTAX           Syntax;
    DWORD                     cbLength;
    DWORD                     dwFlags;
    WCHAR                     szDeviceName[MAX_PATH];
    WCHAR                     szVolumeLabel[MAX_PATH];
    DWORD                     dwSerialNumber;
    DWORD                     rgdwMaximumComponentLength[2];
    DWORD                     dwFileSystemFlags;
    WCHAR                     szFileSystem[32];
} CLUSPROP_PARTITION_INFO, *PCLUSPROP_PARTITION_INFO;
 

Members

Syntax

Member of the CLUSPROP_VALUE structure describing the format and type of the partition information.

cbLength

Member of the CLUSPROP_VALUE structure indicating the count of bytes in the partition information data. The count does not include the data in the Syntax or cbLength members.

dwFlags

Member of the CLUS_PARTITION_INFO structure that describes the disk. One of the following flags is valid:

Partition flag value	Description
CLUSPROP_PIFLAG_STICKY	The drive letter is sticky.
CLUSPROP_PIFLAG_REMOVABLE	The disk is removable.
CLUSPROP_PIFLAG_USABLE	The disk is formatted with a file system that is usable by the Cluster Service.

szDeviceName

Member of the CLUS_PARTITION_INFO structure that describes the device name for the disk, such as C:. No backslashes are included.

szVolumeLabel

Member of the CLUS_PARTITION_INFO structure that describes the volume label for the disk.

dwSerialNumber

Member of the CLUS_PARTITION_INFO structure that describes the serial number of the disk volume.

rgdwMaximumComponentLength

Member of the CLUS_PARTITION_INFO structure that describes the maximum length, in characters, of a file name component supported by the specified file system. A file name component is that portion of a file name between backslashes.

dwFileSystemFlags

Member of the CLUS_PARTITION_INFO structure that describes the file system. One or more of the following flags are valid:

Flag	Description
FS_CASE_IS_PRESERVED	The file system preserves the case of file names when it places a name on disk.
FS_CASE_SENSITIVE	The file system supports case-sensitive file names.
FS_UNICODE_STORED_ON_DISK	The file system supports Unicode in file names as they appear on disk.
FS_PERSISTENT_ACLS	The file system preserves and enforces Access Control Lists (ACLs).

szFileSystem

Member of the CLUS_PARTITION_INFO structure that describes the name of the file system such as FAT, HPFS, or NTFS.
