RAIDar LED Descriptions 

The first LED column represents the global error status informing you if the ReadyNAS 
device is in normal operating mode, or if it is in a warning or failure condition. 

The other column displays device-specific information, allowing you to view exactly what 
devices might need attention. 

Some LEDs are valid only for disk and volume

LED

Description

Not present

Off: No disk or device is attached.

Normal

Green: Device is in normal operating mode.

Warning or Dead

Amber: The device has failed or is in a state where it 

needs attention.

Inactive spare

This disk is a spare disk on standby.  If a disk fails, this 
disk will automatically take over.

Awaiting resync 

Green: This disk is waiting to resync to the RAID volume. 

Blinking Green: The disk is in the process of resyncing.  

During the resync process, the volume is in degraded 
mode, which means performance is affected by the 
resync process, and another disk failure in the volume will 
render it dead.

Life support mode

The volume has encountered multiple disk failures and is 
in the state of being marked dead.  

However, the ReadyNAS has blocked it from being 
marked dead in case someone accidentally pulled out the 
wrong disk during runtime.  

If the wrong disk was pulled out, shut down the 
ReadyNAS immediately, reconnect the disk, and power 
on the ReadyNAS.  If you reconnect the disk during 
runtime, the ReadyNAS will mark it as a newly added disk 
and you will no longer be able to access the data on it.

Background task active

Blue: The unit is running a lengthy background task, such 
as a system update.
