Class reference

Subclass of CIM_LocalFileSystem

Base class for nonpersistent filesystems of this system, such as tmpfs, cgroups, procfs etc.

Local properties

uint32 MaxFileNameLength

Integer indicating the maximum length of a file name within the FileSystem. 0 indicates that there is no limit on file name length.

boolean CasePreserved

Indicates that the case of file names are preserved.

boolean CaseSensitive

Indicates that case sensitive file names are supported.

uint16[] OperationalStatus

Indicates the current statuses of the element. Various operational statuses are defined. Many of the enumeration’s values are self-explanatory. However, a few are not and are described here in more detail.

“Stressed” indicates that the element is functioning, but needs attention. Examples of “Stressed” states are overload, overheated, and so on.

“Predictive Failure” indicates that an element is functioning nominally but predicting a failure in the near future.

“In Service” describes an element being configured, maintained, cleaned, or otherwise administered.

“No Contact” indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it.

“Lost Communication” indicates that the ManagedSystem Element is known to exist and has been contacted successfully in the past, but is currently unreachable.

“Stopped” and “Aborted” are similar, although the former implies a clean and orderly stop, while the latter implies an abrupt stop where the state and configuration of the element might need to be updated.

“Dormant” indicates that the element is inactive or quiesced.

“Supporting Entity in Error” indicates that this element might be “OK” but that another element, on which it is dependent, is in error. An example is a network service or endpoint that cannot function due to lower-layer networking problems.

“Completed” indicates that the element has completed its operation. This value should be combined with either OK, Error, or Degraded so that a client can tell if the complete operation Completed with OK (passed), Completed with Error (failed), or Completed with Degraded (the operation finished, but it did not complete OK or did not report an error).

“Power Mode” indicates that the element has additional power model information contained in the Associated PowerManagementService association.

“Relocating” indicates the element is being relocated.

OperationalStatus replaces the Status property on ManagedSystemElement to provide a consistent approach to enumerations, to address implementation needs for an array property, and to provide a migration path from today’s environment to the future. This change was not made earlier because it required the deprecated qualifier. Due to the widespread use of the existing Status property in management applications, it is strongly recommended that providers or instrumentation provide both the Status and OperationalStatus properties. Further, the first value of OperationalStatus should contain the primary status for the element. When instrumented, Status (because it is single-valued) should also provide the primary status of the element.

uint64 FileSystemSize

The FileSystemSize property stores the total size of the File System in bytes. If unknown, enter 0.

uint16 IsFixedSize

Indicates whether the File size is fixed at creation time (value = 1) - the file size is fixed, (value = 2) - the file is not a fixed size. The default (value = 0) indicates that this information is not specified. If the File size is not fixed, the ResizeIncrement property should specify the growth increment, in bytes.

0 Not Specified
1 Fixed Size
2 Not Fixed Size

string Name

Unique identifier of the filesystem on computer system.

uint64 BlockSize

FileSystems can read/write data in blocks which are defined independently of the underlying StorageExtents. This property captures the FileSystem’s block size for data storage and retrieval.

string Root

Path name or other information defining the root of the FileSystem.

uint16 PersistenceType

An enumerated value representing the FileSystem’s perception of its own persistence characteristics. This property would typically be set at the time the FileSystem is instantiated and would not be changed by external actions. A value of “Persistent” indicates that the FileSystem is persistent, will be preserved through an orderly shutdown and should be protected. A value of “Temporary” indicates that the FileSystem is non-persistent, should not be protected and may not survive a shutdown. A value of “External” indicates that the FileSystem is controlled outside of the scope of the operating environment and may need to be protected by specialized means. A value of “Other” is provided to allow for additional persistence types, to be described in the OtherPersistenceType attribute, and is expected to be rarely, if ever, used. A value of “Unknown” indicates that the persistence of the FileSystem can not be determined.

2 Persistent
3 Temporary
4 External

string FileSystemType

String describing the type of FileSystem and therefore, its conventions. For example, “NTFS” or “S5” may be listed as well as any additional information on the FileSystem’s implementation. Since various flavors of FileSystems (like S5) exist, this property is defined as a string.

boolean ReadOnly

Indicates that the FileSystem is designated as read only.

uint64 AvailableSpace

AvailableSpace indicates the total amount of free space for the FileSystem, in bytes. If unknown, enter 0.
