About this task

The Volumes screen displays volumes along with their properties.

The volumes table columns

Columns that are displayed by default:

  • Name - the name of the volume
  • Pool - the pool that the volume belongs to
  • Consistency group - the consistency group that the volume belongs to 
    • N/A - indicates that the volume does not belong to a consistency group
  • Thin - indicates whether the volume can use the pool's virtual capacity
  • Mapped - indicates whether the volume is mapped to a host or cluster
  • Size - specified upon volume creation and seen by the host SCSI initiator
  • Used - Used - the sum of bytes that is considered to be in use by the volume
    1. For a THIN volume - the Used value is equal to Allocated

    2. Snapshots at the creation have the same Used value as the source volume

    3. Important Note: for filesystems that do not perform space reclamation and for volumes that are being repurposed, the Used value can report much higher values than actual used by the host

  • Allocated - the sum of the allocated properties of the volume’s descendants. 
    • The value of this property is zero (0) if there are no descendants
    • If the volume is THICK the system will always allocate the entire size. 

    • If the volume is THIN the system will allocate the amount of capacity that is actually in use for user data. 

  • Write protected - states whether the host can write into the volume
  • Creation date - Date and time of the creation of the volume

Columns that are not displayed by default, but can be added to the table:

  • Replication Role - for a replicated volume, this column indicated whether the volume is a source or a target
  • Serial  - the volume's serial number
  • Data Reduction Ration - the ratio between the pre-compressed volume capacity to the compressed volume capacity

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.

The volume capacity counters

Click a volume to open its detailed view. At the top left side of the view you can find the volume's capacity counters.

  1. Size - specified upon volume creation and seen by the host SCSI initiator
  2. Used - the physical capacity that is allocated to the volume and was actually written into
  3. Free - the amount of the volume size that is not in use 
  4. Allocated - the capacity that is allocated for the volume
    • If the volume is THICK the system will always allocate the entire size. 

    • If the volume is THIN the system will allocate the amount of capacity that is actually in use for user data. 

  5. Tree Allocated - the sum of the allocated properties of the volume’s descendants. The value of this property is zero (0) if there are no descendants

InfiniShell instructions

  • Run: vol.query.

GUI instructions

  • Click the Volumes & FS icon on the toolbar on the left.
    The Volumes screen opens, displaying the system's volumes.
