Can't expand volume...

Can't expand volume, despite free space.

Hello, I am running a raid 1+0 with 2 sets of 4 disks, each 2TB.
I had 3 volumes:
A - 500GB
B - 3 TB
C - 4.5 TB

I no longer needed A, so deleted it. As expected, this left 125GB free on each of the individual disks in the array.
I was expecting that I could then resize the two remaining volumes to take advantage of the free space, per the guide:

"You can expand a volume to use up all the available space on the disks it is using. The volume is limited only by the available space on the disk with the least amount of free space."

However when attempting to resize either of the remaining volumes, the max size is the same as the current size.

Why can't I expand my volumes to use the available space?

I am running SoftRaid 5.6.1 and MacOS 10.12.6. There are no errors on any of the disks.

Thanks, John

The problem is the volume you deleted is at the beginning of the disk. SoftRAID does not support moving data around the disk to resize, or breaking out partitions into pieces.

Only the last volume can be resized.

In your scenario, if you deleted volume C, then you could resize B to 7.5TB.

Thanks for the info and prompt reply!

It would be helpful if this limitation were mentioned in the guide as the current wording seems misleading: " only by the available space..."
