REBUILDING THE RAID 5 ARRAY 

If one of the disk drives from the RAID 5 array fails, you need to replace the failed drive 
with a new one and then rebuild the array to re-generate the lost data on the newly 
added drive. 

The LEDs for each disk drive in the array indicate the general state of the corresponding 
disk.  

 

A blue light indicates the disk is powered up properly, while a blank LED indicates the 
disk is not working. 

You can also verify the health of the array by clicking the Ubuntu search icon and then 
entering “disks” in the search bar.

 

 

The 

Disks

 window shows the degraded state of the array.
