crcontrol --dsstat will show you the actual used space of the de-dupes internals
After that an images on media report against your disk pool will tell you everything that is on the de-dupe storage
If you have OpsCenter the reports there will also give you a good idea of what is going on along with de-dupe rates.
Do bear in mind that a 90% used de-dupe pool may just need properly processing to trim it down - i have seen many sites where they are almost out of disk space but it just needs the queue processing many time to get the internal cleanup operations to run through and make more available space - and we are talking in terms of TB's of space that can be freed up.
Lets see your dsstat out put and also crcontrol --queueinfo to get a better idea of where you currently stand
Hope this helps

This tech note say 7.0.1 but is valid for 7.x as well
