As I correctly understand this is a known issue with deduplicated volumes (in version 6.0), namely that the erased space on the deduped vol could`t be reclaimed.
We are still playing with this ancient version of the sofware in our non-productive environment. I only found a workaround suggesting remigration spdata to a new/temporary file on an "external" physical drive , which allows you to get rid of the trash in the spdata file. The dedupe disk was configured for 5TB - appearing currently as 6,45TB file in the windows filesystem - and unfortunately there is no physical space to expand the affacted volume.
My question Is, if is there any update on this issue yet (a new tool and/or an other better workaround ...)? This time we cant upgrade to V8.
thanks,
tomas.
