About this task
The Datasets window displays the properties of InfiniBox filesystems.
- Name - the name of the filesystem.
- Pool - the pool that the filesystem belongs to.
- Size - the size specified during filesystem creation or the latest filesystem modification, and seen by the NFS client.
- This is the maximum amount of data the filesystem can occupy.
- The minimum size is 1 GB.
- Thin - indicates whether the system allocates only the physical disk space needed after data reduction ('Thin'), or allocates the entire filesystem size ('Thick').
- Allocated - the physical disk space allocated to the filesystem.
If the filesystem is Thick, the system allocates the entire filesystem size.
- For example, for a 1GB thick filesystem, Size would be 1GB and Allocated would be 1GB.
If the filesystem is Thin, the system allocates only the physical disk space needed after data reduction.
Data reduction can include zero-elimination and compression.
For example, for a 1GB thin filesystem, Size would be 1GB and Allocated would be between zero – 1GB. If the host wrote just zeros, Allocated would be zero.
- Snapshots - the sum of the allocated physical space of all the filesystem’s descendants. The value of this property is zero (0) if there are no descendants.
- Used - the total amount of the filesystem, in 64KB sections, that contains any written data.
This includes zeroes written for zero-elimination.
- At creation, snapshots have the same Used value as the source filesystem.
Important note: For filesystems that do not perform space reclamation, the Used value can report much higher values than actually used by the host.
- Compression - indicates if compression is enabled for data reduction.
- Data Reduction - the ratio between the data written to the system and the capacity it consumes after compression.
- Mapped/Exported -
- For Unix security style filesystems, indicates if the filesystem is accessible via an export.
- For Windows security style filesystems, indicates if the filesystem is accessible via a share.
- Write Protected - indicates if the host can write into the filesystem.
- Lock State - indicates if the snapshot is locked. Refer to Locking a snapshot.
Note: This setting is sometimes referred to as 'secure lock'.
- Lock Expiry Date - when the locked snapshot will be unlocked.
- Replicated - indicates if the filesystem is replicated asynchronously or synchronously for the purpose of continuous availability or disaster recovery. 'Yes' indicates either a source or a target InfiniBox.
- Serial - the filesystem's serial number.
- Not useful information for filesystems.
- Creation Date - Date and time of the creation of the filesystem.
- Updated At - Date and time of the latest filesystem modification.
- Snapshot Directory Name - the name of the folder in which NFS clients can access the contents of the snapshot.
- Snapshot Directory Accessible - indicates if the .snapshot folder is available for NFS clients.
- SSD Enabled - indicates if the filesystem can use the system's SSD cache.
Note: This setting is sometimes referred to as 'flash cache', 'flash enabled', or 'SSD cache'.
- In the GUI, click the Datasets icon in the left toolbar, and click the Filesystems tab.
In the right-most column of the table heading, click the Settings icon, and select the properties to be included in the table.
The selected data is displayed in the table.
- You can customize the table display. Your changes remain in effect until you click a different icon in the left toolbar.
- Drag a column heading to reposition its column.
- Drag a vertical separator in the heading row to resize the preceding column.
- Click a filter icon in a column heading to apply one or more filters.
- Click the arrow next to a column name to reorder the table entries.
- Click a filesystem to open a detailed view of its capacity counters and other properties.
Specifying the capacity units
Use the unit argument to specify the way the capacity fields of the output are displayed. Available units are:
- B – Byte. For example, 1000000192512
- G – Gigabyte. For example, 1000.00 G
- GB – same as G.
- GiB – Gibibyte. For example, 931.32 GiB
- T – Terabyte. For example, 1.000 T
- TB – same as T.
- TiB – Tebibyte. See GiB above. For example, 0.909 TiB
