volume

Manages volumes, snapshots and mirrors.

Fields

The following table lists the data fields that provide information about each volume. Each field has two names:

  • Field name - displayed in the output of the volume list command and used to specify the columns displayed using the columns parameter
  • Short name - used to specify the columns displayed using the columns parameter

The short name is also used when specifying rows with a filter, for example when specifying a set of volumes about which to get information.

Field Name Short Name Description
accesstime va A value that can be used to determine when this volume was accessed.
actualreplication arf The actual current replication factor by percentage of the volume, as a zero-based array of integers from 0 to 100. For each position in the array, the value is the percentage of the volume that is replicated index number of times. Example: arf=5,10,85 means that 5% is not replicated, 10% is replicated once, 85% is replicated twice.
advisoryquota aqt The advisory quota for the volume, in MB. A value of 0 indicates there are no soft or advisory quotas for this volume.
AdvisoryQuotaExceededAlarm aqa Alarm raised if the volume size is more than the value configured for the advisory quota.
aename aen The accounting entity (AE) name.
aetype aet The type of accounting entity (AE). Value can be:
  • 0 - user
  • 1 - group
allowGrant ag Specifies whether a parent volume grants permission for a child volume to inherit its properties. Value can be true or false.
allowReadforExecute re When set to true(1), allows execution of SUID binaries with only their executable bit set, on a FUSE filesystem. This parameter works in conjunction with the fuse.mount.setuid FUSE option. For more information, see Configuring the HPE Ezmeral Data Fabric FUSE-Based POSIX Client
AlmostFullTopologyAlarm afta Timestamp when Topology Almost Full alarm was raised.
atimeTrackingStartTime atimeinterval Indicates the time at which atimeUpdateInterval is enabled.
aTimeTrackingStartTime is updated to the current time in the following cases:
  • Just started tracking atime, which means that the atimeUpdate frequency was previously zero
  • If the value of atimeUpdate frequency is decreased
  • If the value of atimeUpdate frequency is increased and atime has not been tracked for the duration of the new frequency value
For more information, see Tuning Last Access Time.
atimeUpdateInterval atst Defines the frequency at which the last file access time is updated. For more information, see Tuning Last Access Time.
audited ea Indicates whether 1 or not (0) auditing is enabled for the volume. See Enabling Auditing for the steps to enable auditing on a volume and on directories, files, and tables in that volume.
auditVolume av Indicates whether (1) or not volume accommodates audit logs.

coalesceInterval ci The interval of time in minutes during which only the first instance of an operation on a node is recorded in audit logs, if auditing is enabled. Subsequent identical operations performed on the same node are ignored during the interval. Setting this field to a larger number helps prevent audit logs from growing quickly.

creator on Name of the user that created the volume.
creatorcontainerid ccid ID for the container.
