About this task
The Volumes screen displays filesystems along with their properties.
The filesystems table columns
- Name - the name of the filesystem
- Pool - the pool that the filesystem belongs to
- Thin - indicates whether the filesystem can use the pool's virtual capacity
- Mapped - indicates whether the filesystem is mapped to a host or cluster
- Size - specified upon filesystem creation and seen by the host SCSI initiator
- Used - the physical space that is allocated to the filesystem and was actually written into
- Tree allocated - the sum of the allocated properties of the filesystem’s descendants. The value of this property is zero (0) if there are no descendants
If the filesystem is THICK the system will always allocate the entire size.
If the filesystem is THIN the system will allocate per 64KB written that are not zero.
For example, 1GB thin filesystem might show host wrote 1GB in the Used column and the Allocated column can be anywhere between zero – 1GB. In this example if the host wrote just zeros the Allocated will be zero.
- Write protected - States whether the host can write into the filesystem
- Creation date - Date and time of the creation of the filesystem
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 – GB. For example, 1000.00 GB
- GB – Same as G.
- GiB – Gibibyte. For example, 931.32 GiB.
- T – TB. For example, 1.000 TB.
- TB – same as T.
- TiB – Tebibyte. See GiB above. For example, 0.909 TiB.
- Block –512 bytes. For example, 1907349.
- Click the Volumes & FS icon on the toolbar on the left.
- Click the Filesystems tab.
The Filesystems screen opens.
