So I recently bought 4 new 3TB drives to upgrade my Pegasus R4 from 4TB (3TB RAID 5) to 12TB (9TB RAID 5).

I followed along to a couple tutorials online and I replaced each drive, and had Promise Utility rebuild the RAID 5 each time. 4 Drives later, all the data is still on the drive and functional like normal.

Tutorial: eclecticlight.co/2016/02/11/keeping-your...ise-pegasus-r4-raid/

The Promise App shows the drive as 12TB with 9TB Logical Drive. Ok, thats correct...but the problem is the OS X Finder doesn't show the new storage space. It's still just showing 3TB...how can I get my system to recognize the new, larger drives that are now installed so I can utilize the extra space?

I think tis something to do with resizing the disk in Disk Utility, but I don't see any option for that anywhere so if you could, please point me i the right direction.

Thanks!

If I select the drive in Disk Utility and click on Partition, it shows me a screen where I can change the partition size, I think...? If I change it to 9TB it shows the pie chart as one partition - I'm thinking this might be correct, but not sure...

Thoughts?

Okay so just in case anyone runs in this in the future just changing the "size" on the partition page does work as far as reclaiming the "free space" section of the drive. Once you do this, the drive will show up as the whole of the available space in the Finder.
