This is probably fragmented space on your DMX that you can not reclaim. I too lost about 2.5TB due to fragmentation.

I have these rather simple CLI commands I run and kick the ouput to a file.  First command displays device created but not on a channel; the second displays configured and unconfigured space on each drive.  Depending on the space available on each disk then you can determine if you can create more volumes.  One trick to use smaller amounts of uncofigured space is to create raid-5 volumes as they use less space per disk since they are spread over more disk drives than tradiitional raid-1 volumes.

symdev -sid XXXX list -noport > XXXXdata.txt
symdev -sid XXXX list -da all -space >> XXXXdata.txt
