Optimize unused space in RAID5 due to bigger HDD in spare parts change

  • 772

I have started with 3x250 GB SATA array, but the old HDDs failed one by one and when the spare parts came they where bigger disk inside and I recently ended up with 3 HDDs of 500 GB.

enter image description here

I see reported unused space 698.6GB, can I optimize the present configuration?

    Sure, this is an easy process...

    Once the rebuild is done, you can either use the "Unused Space" to create another Logical Drive (e.g. Logical Drive 3), or you can Extend Logical Drive 2 to utilize the extra space.

    Once this is done, you'll see a larger block device available to your operating system.

    • If this is Windows, the free space will be available and you'll need to extend it in the Disk Management console.
    • If this is Linux, you'll need to make fdisk partition changes (or LVM craziness) in order to use the new space.
