Can you send in your logs (see the Sending Logs link in my sig)?
Do you use snapshots?
What kind of LUNs do you have? Thick LUNs are recommended and when you create these the space is taken up instantly. Whether the LUN is empty or full it takes up the same amount of space (unless you are using snapshots in which case as changes are made over time even more space will be consumed until the snapshots are deleted).

Thanks. Not using snapshots. iSCSI LUNs are all thick and LUNs total capacity is 27.25 TB of a 36TB ReadyNAS. Still only have 1.9 TB available. Logs on their way momentarily.

Your email did not have the logs zip attached to it.

When you create a thick LUN the space for the full capacity of the LUN is consumed. So deleting a LUN and creating a new one with the same space won't end up freeing up space.
