Volume kernel states

The volume kernel state indicates the accessibility of the volume. The volume kernel state allows a volume to have an offline (DISABLED), maintenance (DETACHED), or online (ENABLED) mode of operation.


  Note   No user intervention is required to set these states; they are maintained internally. On a system that is operating properly, all volumes are ENABLED.


The following volume kernel states are defined:

DETACHED volume kernel state

Maintenance is being performed on the volume. The volume cannot be read from or written to, but certain plex operations and ioctl function calls are accepted.

DISABLED volume kernel state

The volume is offline and cannot be accessed.

ENABLED volume kernel state

The volume is online and can be read from or written to.
