Question about upgraded to larger hard drives

I have a MyCloud EX4100 configured as raid 5

I had 4x 1TB hard drives in it. When I looked at the storage raid volume it read:
Volume_1 Raid 5 2.94TB.

I upgraded the hard drives to 4x 2TB. I changed 1 hard drive at a time and just rebuilt the raid until all 4 were done.

I forget exactly what it said, but I selected to expand the unused space and it created a second volume. Now when I look at the storage raid volume it reads:
Volume _1 Raid 5 2.94TB
Volume_2 Spanning 3.94TB

However I just want one 1 Raid_5 volume to use all of the space. Is there anyway I can get ride of the volume 2 and expand volume 1 to use all the available space ?

Hi eddie4,

Maybe you should try contacting WD’s Technical Support about this.

ok thanks I will create a support case

What was the ultimate outcome of this?

I had to copy everything off, reformat then copy everything back on
