java.lang.Object

java.lang.Enum<StorageVolume.VolumeState>

org.apache.hadoop.ozone.container.common.volume.StorageVolume.VolumeState

All Implemented Interfaces:

Serializable, Comparable<StorageVolume.VolumeState>

Enclosing class:

StorageVolume

public static enum StorageVolume.VolumeState
extends Enum<StorageVolume.VolumeState>

VolumeState represents the different states a StorageVolume can be in. NORMAL => Volume can be used for storage FAILED => Volume has failed due and can no longer be used for storing containers. NON_EXISTENT => Volume Root dir does not exist INCONSISTENT => Volume Root dir is not empty but VERSION file is missing or Volume Root dir is not a directory NOT_FORMATTED => Volume Root exists but not formatted(no VERSION file) NOT_INITIALIZED => VERSION file exists but has not been verified for correctness.
