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:
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.
The volume is offline and cannot be accessed.
The volume is online and can be read from or written to.
