I am doing "poweroff" after exiting vi. Are there any other processes that might be keeping the drive open?

I'm trying to follow the steps outlined by Joonas but I'm running into a problem when I try to check the file system on my disk before resizing the partition. I'm getting an error message saying /dev/md2 is in use. Is there any way to tell what process(es) are using it? Edit: I did some more investigation. I haven't used…
