I have got a 10 disk (16 TB) RAID-6 array (AVAGO MegaRAID SAS 9380-8e) in a Supermicro JBOD enclosure. The controller started beeping today and one disk is blinking red/blue. I entered the AVAGO control software and 9 of the disks are shown as "Online", while one of them is shown as "Rebuild" with a Progress of 20%.
My question is: What does it mean that the disk is rebuilding? I expected that I would have to swap the failed disk before anything can be rebuild.
Thanks for your help! Gregor
