Something is holding on to the volume.

Did you try this terminal command?

sudo diskutil unmount force disk#

Get the disk# from SoftRAID, expand the volume tile, the disk identifier is the disk#

You can also run lsof to try to see what is using the volume:

It is in the form:

sudo lsof /Volumes/myDrive

Might give you a clue

Hi I'm running SoftRAID 6.2.1 and I recently had to reformat my volume. It mounts and copies fine, but it won't unmount. I tried unmounting from the Apple UI, but nothing happens other than the occasional whirling rainbow beachball of doom. I then tried using SoftRAID, which did almost nothing, as well. It says it's "unmounting" but nothing has happened for 30 minutes. I've had this issue before on my older volume and older OSs, but I was able to force eject. Now even that is not an option. Any ideas?
